Purse Illumination with EL Wire and LED Touch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing purse lighting systems are cumbersome, prone to accidental activation, and do not effectively illuminate the interior from the bottom and sides, often using point sources and requiring multiple components, which are not aesthetically pleasing and can lead to battery discharge without user knowledge.
Innovation Solution
A purse illumination system using light-emitting fabrics or electroluminescent wires that provide ambient lighting from the bottom and sides, with touch-sensitive switches and capacitive timing circuits to prevent accidental activation, and can be used both inside and outside the purse for aesthetic and functional purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional point light sources and multiple components are used, then illumination function is provided, but device complexity increases and aesthetic appeal deteriorates
Solution Approach 1:
The patent combines multiple light sources (EL wire and LED) into a single integrated illumination system that can be attached to purses. The EL wire provides continuous ambient lighting while LED components provide targeted illumination, merging different lighting technologies into one unified device that reduces complexity compared to separate traditional lighting systems.
Solution Approach 2:
The illumination device serves multiple functions: it illuminates the purse interior, provides aesthetic lighting effects, and can be attached to various purse types. The system incorporates both EL wire for continuous ambient light and LED components for versatile lighting patterns, making it a multi-functional solution that replaces multiple separate components.
2Ease of operation
If push switches are used for activation, then ease of operation is improved, but reliability deteriorates due to accidental activation
Solution Approach 1:
The patent replaces traditional mechanical push switches with a touch-sensitive electronic switch system. This substitution eliminates the mechanical pressing action that causes accidental activation while maintaining ease of operation through gentle touch. The electronic sensing mechanism provides more reliable activation that cannot be triggered by items within the purse.
3Area of stationary object
If lighting systems are positioned to illuminate from top, then illumination coverage is improved, but device complexity and installation difficulty increase
Solution Approach 1:
Instead of positioning light sources at the top of the purse to illuminate downward, the patent inverts the approach by placing EL wire along the bottom edge and using reflective surfaces to bounce light upward and across the interior. This inversion simplifies positioning while maintaining comprehensive illumination coverage.
Solution Approach 2:
The patent uses reflective surfaces and angled positioning to redirect light in multiple dimensions. By strategically placing EL wire and LED components and using reflective elements, the system achieves comprehensive illumination coverage without requiring complex multi-point positioning, leveraging optical reflection to expand light distribution.
4Power
If heavy traditional lighting systems are used, then illumination power is improved, but weight increases making the purse cumbersome
Solution Approach 1:
The patent changes the power delivery parameters by using high-efficiency EL wire and LED components that provide adequate illumination with minimal power consumption. This allows the lighting system to maintain sufficient illumination power while using a lightweight battery and component assembly that does not significantly increase the purse weight.

AI summary
A purse illumination assembly including a power source, a light emitting portion, a voice-sensitive switch, and a circuit assembly connecting the light emitting portion to the power source through the voice-sensitive switch. The light emitting portion may be a light emitting fabric or may include EL wire alone or in combination with LED lights to provide both lighting and a decorative effect. A driver circuit may be included for driving both the EL wire and the LED lights.
