Hinged Wearable Illumination Device With String Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable illumination devices lack a convenient and secure method to attach to zipper pulls or sliders, and they often fail to provide versatile lighting options and durability for outdoor use.
Innovation Solution
A wearable illumination device with a hinged housing made of soft, durable, and semi-transparent material, featuring a coupling mechanism with a flexible string-like material that allows easy attachment to zipper pulls or sliders, and includes a switch-activated illumination source with multiple modes and weather resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid attachment method is used to secure the illumination device to a zipper pull, then the attachment strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent employs a flexible string-like coupling portion that threads through the zipper pull and illuminating device housing. This flexible element provides sufficient attachment strength to secure the device while allowing easy threading and removal operations, resolving the contradiction between strong attachment and ease of operation.
2Illumination intensity
If the housing is made completely transparent to maximize light output, then the illumination intensity is improved, but the durability and weather resistance deteriorate
Solution Approach 1:
The housing is designed with semi-transparent material rather than completely transparent material. This local quality adjustment allows sufficient light transmission for effective illumination while maintaining the structural integrity and weather resistance needed for outdoor durability, resolving the contradiction between light output and reliability.
3Ease of operation
If the housing material is made soft and flexible to improve ease of operation, then the ease of operation is improved, but the structural strength deteriorates
Solution Approach 1:
The housing combines soft, flexible material properties with sufficient structural strength through composite construction. The material is soft enough to allow compression for switch actuation and easy attachment operations, while maintaining the structural integrity needed to protect internal components and withstand outdoor conditions, resolving the contradiction between ease of operation and structural strength.
