Solution Overview
Problem
Conventional lighting devices, such as ceiling lamps and standing work lights, often fail to provide sufficient illumination in dimly lit areas, like automobile engine bays, and rely on disposable batteries that require frequent replacement, which is inconvenient.
Innovation Solution
A portable, rechargeable lighting apparatus with an elongated housing, extendable rods, hooks, and a rechargeable battery, featuring LEDs and a photoluminescent coating for extended illumination, along with a charging port for power replenishment, allowing for adjustable and hands-free lighting in dark environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting devices (ceiling lamps, standing work lights) are used, then they provide stable illumination, but they cannot adequately illuminate dimly lit regions and lack portability
Solution Approach 1:
The lighting system is divided into a stationary base unit and a portable handheld unit. The base unit contains the rechargeable battery and charging port, while the handheld unit contains the LEDs and photoluminescent coating. This segmentation allows the portable unit to be lightweight and easy to operate in dimly lit regions, while the stationary base provides recharging capability.
Solution Approach 2:
A rechargeable battery serves as an intermediary energy storage device between the AC power source (via charging port) and the LED light sources. This allows the lighting apparatus to store energy and operate portably without direct connection to power sources, resolving the contradiction between stable illumination and portability.
2Ease of operation
If single-use disposable batteries are used, then they are convenient to use, but they require frequent replacement and maintenance of backup batteries
Solution Approach 1:
Instead of discarding depleted disposable batteries, the system recovers energy by providing a charging port on the base unit that can recharge the battery in the handheld lighting apparatus. This eliminates the need for frequent battery replacement and maintenance of backup batteries, while maintaining operational convenience.
Solution Approach 2:
The lighting apparatus is designed to be self-recharging through the charging port that accepts power from external sources. The battery automatically recharges when connected, eliminating the need for user intervention to replace batteries, thus reducing time loss while maintaining ease of operation.
3Ease of operation
If the lighting apparatus is made portable with battery power, then it enables mobility, but it requires frequent battery replacements or recharging
Solution Approach 1:
The system performs preliminary charging action by providing a charging port on the base unit that can recharge the battery before it is fully depleted. This preliminary recharging capability extends the operational duration of the portable lighting apparatus, allowing it to remain mobile and operational for longer periods without requiring battery replacement.
4Duration of action of moving object
If photoluminescent coating is added to extend illumination duration, then it provides prolonged light emission, but it adds to the device complexity
Solution Approach 1:
The photoluminescent coating is merged with the housing surface of the handheld lighting apparatus. This coating absorbs light during the day or from LED illumination and re-emits it during darkness, extending illumination duration without requiring separate components or complex mechanisms. The coating integrates seamlessly with the existing structure, minimizing added complexity.
