Flexible Light Diffuser Casing for Headlamp Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light diffusers for headlamps are cumbersome, complex to install, and often require specific headlamp models, limiting their versatility and practicality for mountain activities, especially when used for diffuse lighting during rest periods.
Innovation Solution
A compact, multifunctional light diffuser box made from thermoplastic polyurethane materials, featuring a separable cavity for headlamp storage and a translucent separator that allows for diffuse light emission, with an elastically deformable envelope for easy lamp operation and a versatile design accommodating different headlamp sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid housing is used for the light diffuser, then the structure provides stability and protection, but the weight and bulk increase, making it inconvenient for mountain activities
Solution Approach 1:
The patent employs a flexible, translucent membrane material to form the housing of the light diffuser. This flexible shell replaces traditional rigid housing structures, providing the necessary protection and structural integrity while significantly reducing weight and bulk. The membrane material maintains its form when inflated or pressurized by the light source, creating a stable yet lightweight structure ideal for mountain activities.
2Reliability
If the housing is made rigid to maintain shape, then structural integrity is improved, but adaptability to different headlamp sizes is reduced
Solution Approach 1:
The patent utilizes a dynamic, flexible membrane housing that can adapt its shape and size. The membrane material allows the housing to conform to different headlamp dimensions while maintaining structural integrity through internal pressure or support structures. This dynamic design enables the same diffuser to accommodate various headlamp models without compromising structural strength.
Solution Approach 2:
The patent changes the physical state or properties of the housing material to achieve adaptability. The membrane material can transition between different states (flaccid when deflated, rigid when pressurized), allowing it to adapt to different headlamp sizes and shapes while maintaining structural integrity during use.
3Illumination intensity
If additional accessories are added to create a light diffuser, then lighting functionality is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the housing structure and light diffusing function into a single integrated component. The translucent membrane material serves dual purposes: it forms the protective housing structure and simultaneously acts as the light diffusing element. This merging eliminates the need for separate diffuser accessories, reducing overall device complexity and simplifying installation.
Solution Approach 2:
The patent designs a universal housing structure that performs multiple functions: protection, light diffusion, and structural support. The translucent membrane material provides both structural integrity and light diffusing properties, making the housing itself a multi-functional component that eliminates the need for additional specialized accessories.
4Quantity of substance
If the storage bag is used as a light diffuser, then storage capacity is maintained, but installation complexity increases due to strap removal and reattachment
Solution Approach 1:
The patent merges the storage bag and light diffuser functions into a single integrated design. The translucent membrane housing serves as both the storage container and the light diffusing structure, eliminating the need for separate components that would require removal and reattachment. The unified design allows users to transition between storage and lighting modes without complex manipulation.

Function Achieved in This Case
The solution provides a lightweight, easy-to-use, and versatile light diffuser that protects the headlamp while offering diffuse lighting without the need for additional accessories, enhancing usability in various mountain activities and reducing bulk and weight.
Implementation Method 1
a light diffuser arranged to receive a light beam emitted by the lamp and to diffuse the beam on the envelope of the housing
Implementation Method 2
The envelope of the first housing is made of an elastically deformable material, so as to allow the switching on and off of the lamp placed in the housing

AI summary
The invention relates to a light-diffusing housing (2) comprising an envelope (3) defining a cavity and having a resealable opening (5) configured to allow the insertion of a headlamp (1) inside the housing (2). A light diffuser is arranged within the housing (2) to receive a beam of light from the headlamp (1) and diffuse said beam onto the envelope (3). The light diffuser is made of a translucent or transparent material so as to allow the beam to pass through it, and the envelope (3) is made of a translucent material. The invention also relates to a method of using the housing (2).
