Adjustable Lighted Purse Liner for Dark-Content Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional purses lack interior lighting, making it difficult to view contents in dark environments or when items are crowded.
Innovation Solution
A lighted bag liner is integrated into the interior of a purse, featuring a flexible lighting material with mini light strings, an on/off switch, and a rechargeable power unit, allowing users to easily illuminate the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional purses are designed to carry many items comfortably, then the purse capacity and comfort are improved, but the ability to view contents in dark locations deteriorates
Solution Approach 1:
A flexible lighted liner is introduced as an intermediary element between the user and the purse contents. The liner contains integrated LED lighting that illuminates the interior space, enabling visibility of items without requiring the user to manually extract or manipulate objects. The liner acts as a mediating illumination layer that conforms to the purse's interior geometry.
Solution Approach 2:
The lighting solution employs a flexible thin film liner that can conform to the irregular interior surfaces of the purse. This flexible membrane structure allows the light source to adapt to various purse shapes and sizes while maintaining close proximity to the contents for effective illumination without adding significant bulk.
2Illumination intensity
If existing lighting devices are mounted within purses, then illumination capability is improved, but the device size and complexity increase
Solution Approach 1:
The patent combines multiple functions into a single integrated liner assembly: the flexible mounting substrate, the LED light sources, the diffusing material, and the power connection points are all merged into one unified component. This eliminates the need for separate mounting brackets, individual light fixture assemblies, and complex wiring harnesses, thereby reducing overall device complexity while maintaining lighting functionality.
3Illumination intensity
If traditional light sources are used in purses, then illumination is provided, but power consumption increases and heat generation occurs
Solution Approach 1:
The patent replaces traditional incandescent or halogen light sources with LED (light-emitting diode) technology. LEDs are solid-state devices that convert electrical energy directly to light with minimal heat generation, substituting the thermal radiation mechanism of traditional bulbs with electroluminescence. This substitution dramatically reduces power consumption and eliminates excessive heat generation while providing sufficient illumination.
Solution Approach 2:
The lighting system incorporates adjustable brightness parameters through controllable LED intensity levels. The system can operate at multiple brightness settings, allowing users to select lower power consumption modes when full illumination is not required. This parameter adjustment capability enables optimization between illumination needs and power conservation, extending battery life while maintaining usability.

AI summary
A lighted bag liner added to an existing purse/bag OR built within the interior (bottom and/or sides) of a new purse. It is on a mesh-netting. When illuminated (i.e., turned on by a switch or phone app), it will help its user see the contents of their purse/bag.
