Portable Light Stowable Hanger and Rotatable Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable lights often require complex assembly and disassembly of multiple parts, such as reflectors, lenses, and heat sinks, which can lead to reliability issues and increased costs, and lack flexibility in directing light sources.
Innovation Solution
A portable light design featuring a stowable hanger and rotatable clip, with a light source module that includes a reflector, heat sink, and lens forming an integral unit that can be easily inserted and secured within the light body, allowing for improved assembly and disassembly while providing flexible light direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional lights have light sources mounted in a way that requires assembly of multiple parts (reflector, lens, light source, control circuit board, heat sink), then the light can be adjusted and maintained, but the assembly complexity and disassembly risk increase
Solution Approach 1:
The patent combines multiple light source components (reflector, lens, light source, control circuit board, heat sink) into a single integrated light source module. This merging reduces the number of separate parts that need to be assembled and handled, thereby simplifying the assembly process and reducing the risks associated with complex multi-part assembly while maintaining the functional capabilities of each individual component
2Adaptability or versatility
If conventional lights have fixed light source orientation, then the structure is simpler, but the flexibility in directing light is limited
Solution Approach 1:
The patent introduces a rotatable light source module that can be rotated to different angular positions relative to the light body. This dynamic capability allows the light direction to be adjusted and adapted to various illumination needs while maintaining a relatively simple overall structure, avoiding the need for complex pivoting and rotating mechanisms by using a straightforward rotation interface
3Ease of repair
If conventional lights have permanent light source assembly, then the structural integrity is maintained, but the ease of replacement and maintenance decreases
Solution Approach 1:
The patent segments the light source components into a modular light source module that can be easily removed and replaced as a single unit. This segmentation is achieved through a retention mechanism that secures the module during operation but allows for straightforward removal and reinstallation, thereby facilitating easy maintenance and replacement while maintaining structural integrity through proper retention during use

AI summary
A portable light may comprise: a light body defining at least a part of a passage, a light source supported by the light body, a switch for controlling the light source, and a deployable hanger for hanging the light from an object. The deployable hanger may comprise: a spring finger proximate the passage, and a hanger ring having at least first and second flat surfaces disposed in the passage and engaging the spring finger. The spring finger bears against the first flat surface of the hanger ring for biasing the hanger ring to a first position and bears against the second flat surface of the hanger ring for biasing the hanger ring to a second position.
