विषय: जन उपयोगी शोध
संबन्धित विभाग : वैज्ञानिक तथा औद्योगिक अनुसंधान परिषद्
मैं आपका ध्यान निम्नांकित शोध बिन्दुओं पर आकर्षित करना चाहता हूँ। यह छोटे छोटे सुधार कई मानों में कुछ महत्त्वपूर्ण बदलाव लाने की क्षमता रखते हैं। मुझे आशा है की अन्य बड़े बड़े शोधों के साथ राष्ट्र की सेवा करने के साथ जन साधारण की जीवन उन्नत करने के लिए आप इन मुद्दों पर भी उचित ध्यान देंगे:
Area 1 Road Side Dust: Pollution in or country has touched astronomical heights, and is impacting all of us in an extremely adverse manner. One of the aspects is shortage of landfill sites. One specific item which is channelsied to landfill sites is dust collected from road side. Due to non-utilisation of this dust for road/building construction or some other purpose the same gets its way to landfill. As the dust is very fine, even after dumping it would still cause pollution by flowing along with wind.
A substantial quantity of such dust is collected from road side daily in cities. Besides occupying space, the accumulated dust dumped in the landfill can also cause the land to become unusable for any other purpose by making it barren. It is evident that research in the field of utilizing this natural resource for amy productive purpose or as a substitute of any natural resource is needed. (Photo attached).
Area 2 Re-use of Inter-Locking tiles: Nowadays, environment-friendly interlocking tiles are commonly used for pavements. These tiles are typically made from ash produced by power plants or other factories. They are solid and capable of withstanding significant loads. Municipalities often replace these tiles once they reach the end of their predetermined lifespan, mainly due to the wear and tear on the top surface. The surface loses its glossy finish because of the friction caused by pedestrian and vehicle movement.
However, even after they become rough, these retired tiles can still be repurposed for applications where a rough surface is either acceptable or even preferred. For example, they could be used as a substitute for bricks in building construction. This would create a complementary solution, benefiting both activities and serving a dual purpose. Reusing these tiles would reduce the amount of waste generated, while also preventing soil degradation by eliminating the need to dig for raw materials to produce new bricks. Additionally, repurposing the tiles would help conserve the environment by reducing the significant heat generated during the brick manufacturing process.
Further research could be conducted to develop suitable models of interlocking tiles that, after their initial use, can serve as viable substitutes for bricks in construction.
Area 3 Cleaning Trees: With the rising pollution levels in Delhi, tree and plant leaves have become hotspots for dust accumulation, which, when disturbed by the wind, contributes further to the growing pollution. As a result, cleaning trees has been included as a key action under the Graded Response Action Plan (GRAP). Currently, fire tenders are deployed to perform this task on roads, but the water nozzles used by these fire tenders are not well-suited for the job. These nozzles are inefficient for cleaning tree leaves with high-pressure water, consuming large amounts of water while achieving minimal results. This approach may not be sustainable in the long term, as it could place undue strain on already scarce water resources.
Given the growing pollution, tree cleaning is likely to become a regular task. Additionally, trees with clean, dust-free leaves are visually more appealing. Therefore, there is a need to develop a more effective and efficient water discharge system specifically designed for cleaning tree leaves. This could help address both the environmental and aesthetic concerns in a sustainable manner.
Area 4 Dustbins: Typically, people prefer not to touch a dustbin when disposing of garbage. However, Indian Railways (IR) has taken a different approach. While most dustbins commonly use foot pressure to open the lid, IR is installing bins in premium trains where the lid must be manually pulled up to dispose of waste. This design is impractical and unhygienic. It should be reconsidered and replaced with a more user-friendly and sanitary alternative. A new, more efficient design that allows for touchless disposal should be developed to enhance convenience and cleanliness.
Area 5 Akahd Jyoti: बाजार में अखंड ज्योति के दीये उपलब्ध हैं। ये सभी बाती को आगे बढ़ाने के लिए सुसज्जित नहीं हैं। नवरात्रों, जागरण और कई अन्य अवसरों के दौरान लोग कई दिनों / हफ्तों तक अखंड ज्योत जलाते हैं। चूंकि बाती में केवल कुछ घंटों का जीवन होता है, इसलिए इसे आगे बढ़ाना पड़ता है, लेकिन उपयोगकर्ता को आगे बढ़ना मुश्किल लगता है क्योंकि बाती राख में परिवर्तित हो जाती है और इसे पकड़ने और खींचने के लिए कुछ भी नहीं होता है। जिस किसी ने भी पुराने दिनों में मिट्टी के तेल के लैंप देखे हैं, उसे पता होगा कि एक घूमने वाला बटन है जिसके साथ आप बिना किसी परेशानी के बाती को आगे बढ़ा सकते हैं। यहां भी यही प्रणाली लागू की जा सकती है और दीया का एक बेहतर विन्यास पेश किया जा सकता है। वर्तमान डिजाइन के तहत, बाती को आगे बढ़ाना मुश्किल है, व्यावहारिक रूप से ऐसा करने के लिए आपको लो को बंद करके बत्ती को चिमटी से पकड़ कर आगे बढाना पड़ता है.
Area 6 Stick to pick trash: Our markets, roads, and tourist areas are often cluttered with garbage, making it difficult to find a spot free from litter. A significant portion of this waste consists of empty plastic wrappers. Currently, the primary method of cleaning these areas is sweeping, which is both inefficient and labor-intensive. While sweeping may cover the entire area once, the rest of the day is typically spent focusing on picking up the most visible trash, like wrappers, to improve the area’s appearance quickly with minimal effort.
To streamline this process, a specialized tool or stick could be developed to allow workers to efficiently collect litter without bending over. This simple tool could be made available to municipalities, enabling workers to stand while gathering trash, making the task quicker and less strenuous. Such an approach could improve the cleanliness of our public spaces with less manpower and effort. This method could also be valuable in areas where full-fledged sweeping is not possible, such as forests or small hills etc.
Area 7 Light Poles: On roadways, we often see streetlight poles, which are generally quite tall, with some being exceptionally high. Given the advancements in lighting design and efficiency over the years, this traditional standard of pole height requires reconsideration. Low-height poles can be seen giving efficient results in campuses, private housing colonies etc. whereas most agencies in public sector continue to follow outdated standards. The excessive height not only increases costs but also creates challenges related to transportation, installation, and ongoing maintenance. Therefore, it is important to recalibrate these old standards to reflect modern needs and technologies.
Area 8 Hand held mike: It is often observed that journalists and other professionals use handheld microphones during interviews. However, as the microphone position frequently shifts between the speaker and the listener, this movement can lead to interruptions or cuts in sound, especially when the microphone is moved too often. To address this issue, a microphone with two spokes could be developed. One spoke would always face the journalist, while the other would point towards the interviewee. This design would ensure consistent audio capture, reducing disruptions and improving the quality of the interview. (Like
Area 9 RO Design: Improved RO Design: According to the Central Pollution Control Board (CPCB), the use of RO water purifiers for TDS levels below 500 is prohibited. However, despite this regulation, RO purifiers have become omnipresent in households, driven by relentless advertising campaigns that portray them as essential life-saving devices. Non-RO water is often stigmatized as unfit for consumption, creating a widespread misconception.
Within this overarching issue lies a more critical concern with significant health implications. Medical standards dictate that drinking water should ideally have a TDS level around 150; anything below this threshold is deemed hazardous. However, RO machines available in market lack the flexibility for users to adjust the TDS level according to their needs. Technicians typically set the TDS level based on the current water quality, often opting for a very low setting to ensure a sweet taste, which is perceived as desirable. The problem arises when the quality of supplied water fluctuates, as technicians are called repeatedly to reset the TDS level. Moreover, if the quality of supplied water improves, the TDS level in RO water would drop to dangerously low levels, maintaining the sweet taste, without users' awareness, potentially compromising their health.
To address these challenges, it is imperative to develop RO models with enhanced features. CSIR could play a pivotal role in this by spearheading the research and development of RO purifiers that offer adjustable TDS settings, empowering users to tailor water quality to their specific requirements. By bridging this technological gap, we can ensure safe and reliable access to drinking water for all.
Area 10 Trolly for broken down vehicle: In case of vehicular breakdowns, traffic police utilize cranes to clear the roadways. However, these cranes are primarily designed to handle vehicles having operational wheels. When faced with situations such as broken axles or tire punctures on large vehicles, there is a lack of appropriate pulling mechanisms available.
As a consequence, traffic congestion resulting from such incidents is a common occurrence, particularly on highways frequented by heavy trucks. Such traffic congestions are a huge loss to the nation and with increase in traffic the number of such incidents is also on rise calling for urgent steps to handle the situation.
Addressing this issue may not be overly complex. The development of a specialized crane capable of extracting vehicles with broken axles is conceivable. Such a solution could involve the implementation of a small trolley positioned beneath the incapacitated vehicle to facilitate the pulling process.
An illustrative example of this concept can be found in the film "Bhuj" starring Ajay Devgan, wherein an Air Force plane with a malfunctioning front wheel makes a successful emergency landing atop a moving ruck.
Area 11 Water Conservation: Given the alarming rate at which potable water is disappearing from our planet, the urgent need to conserve this invaluable resource has reached a critical juncture. Despite the availability of water-efficient aerators in the market for an extended period, their widespread adoption remains lacking. These aerators significantly reduce water consumption without compromising on quality. Installing such aerators on all wash basins and kitchen sink taps could lead to substantial water savings. However, market acceptance of these aerators is low as the model available are not robust and require frequent maintenance. This simple and straightforward method has the potential to greatly contribute to water conservation efforts, and these modifications can be easily implemented on existing taps. To address this issue, further research may be undertaken to improve the design of water-efficient aerators to encourage its market acceptance.
Area 12 Umbrella Design: It is often observed that when providing cover to senior dignitaries, such as the Prime Minister or Governors, the straight rod of the umbrella creates a problem as it does not give full coverage. The umbrella is typically designed to cover only the person holding it or, at most, the person standing adjacent to them, but not someone standing at a distance. To address this issue, a tilt in the straight rod is needed to provide full coverage for the other person as well. A new design could be developed to incorporate this feature, ensuring better coverage and comfort.
Area 13 Dust & Noise: जब भी कार की खिड़की के शीशे बंद होते हैं तो घुटन पैदा होती है, लेकिन जब आप इसे खोलते हैं तो बाहर की धूल और शोर अंदर आता है । इस कारण बाहर मौसम अच्छा होने के उपरांत भी कई दफा एसी चलाना पड़ता है। इसलिए कृपया एक ऐसी प्रणाली तैयार करें जहां एक झिल्ली/जाली को इनलेट में फिट किया जा सके जिससे हवा छन कर आए और कोई घुटन पैदा किए बिना धूल और शोर से छुटकारा पा सके। यह सीधे ईंधन दक्षता में सुधार करेगा और पर्यावरण को बचाने में मदद करेगा।
Area 14 Height Issue: On several occasions, I have noticed that individuals with shorter stature often struggle to find a balance between maintaining proper control over the speed, brake, and clutch pedals while also having a clear view of the road ahead. Many short-statured drivers are barely able to raise their necks enough to get a proper glimpse of the front view. This not only makes driving uncomfortable but also increases the risk of accidents.
To address this, you may consider developing a dummy floor that is about 5-6 inches high. This floor could be equipped with suitable false fittings to raise the height of the brake, clutch, and accelerator pedals. By allowing the driver to raise their seat height, this modification would enable a more comfortable and safer driving experience with a clear view of the road ahead.
Area 15 Pollution: When a vehicle is not used for several days, its pollution levels tend to increase. As a result, during the pollution check renewal process, the Pollution Control Centre often advises running the vehicle for 100 kilometers before expecting a successful test result. This situation is problematic for two main reasons: (i) it seems unnecessary to run the vehicle and contribute further to pollution, and (ii) it is risky to drive with an expired certificate. A solution to this issue should be explored to prevent these inconveniences and ensure both environmental and safety concerns are addressed.

Area 16 Energy savings: The design of traditional gas burners used in a common household may be reviewed to improve fuel efficiency. A significant amount of heat goes waste from all sides of a utensil placed on the fire. The picture below shows how a local hawker is trying to save the heat by
surrounding the flame with a tin cover. Any design improvement in the gas burner used in common household can lead to saving of huge quantity of fuel.
