Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-free lighting solutions, such as those integrated into headgear or eyeglasses, are often expensive and bulky, making them undesirable for hands-free illumination needs.
Innovation Solution
Compact light button devices with a stepped housing configuration and a switch mechanism that allows for on/off configurations using a coin cell battery and LED light source, enabling secure attachment to a surface and selective energization of the light source, thus providing inexpensive and versatile lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light sources are mounted to headgear or eyeglasses for hands-free lighting, then hands-free illumination is achieved, but the device becomes expensive and bulky
Solution Approach 1:
The invention divides the lighting system into a small, simple button-shaped unit that can be independently attached to surfaces, separating it from complex headgear or eyeglasses. This segmented approach allows hands-free lighting without the bulk and cost of integrating lights into wearable items.
Solution Approach 2:
The patent transitions from wearable integration (3D complex structure on body) to surface mounting (2D attachment on various surfaces). By changing the dimensional approach from body-worn to surface-attached, the device achieves hands-free operation without the bulkiness of traditional solutions.
2Illumination intensity
If conventional flashlights are used for task illumination, then focused light is provided, but the device must be held and becomes cumbersome
Solution Approach 1:
The invention extracts the essential lighting function from the cumbersome flashlight body, creating a minimal button-shaped device. By taking out only the necessary components (light source, battery, switch) and eliminating the need for a handle or complex housing, the device provides illumination without requiring it to be held.
Solution Approach 2:
The button device is designed to be attached to surfaces where it can illuminate tasks autonomously without human handling. The push-button switch enables self-operated control, and the surface mounting allows the device to serve itself in providing hands-free illumination.
3Ease of operation
If hands-free lighting is implemented through wearable devices, then illumination is provided, but storage space requirements increase
Solution Approach 1:
By segmenting the lighting function into a small button unit, the invention dramatically reduces the volume required for storage compared to wearable devices. The compact button shape with minimal components allows it to fit in small spaces without the bulk of headgear or eyeglass integration.
Solution Approach 2:
The button device is designed as a simple, inexpensive unit with a coin cell battery that can be easily replaced. This disposable-like approach allows for compact design without the need for durable, space-consuming wearable structures, as the device can be economically replaced rather than maintained.
