Biodegradable Lanyard Link with Integrated Folding Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lanyard strap and link devices are complex and costly, with limited biodegradability, leading to environmental concerns when disposed of in large quantities.
Innovation Solution
A one-piece, foldable lanyard strap and link device made from biodegradable polymers, featuring a lateral tab with living hinges and prongs for securing the lanyard ends, and a vertical tab for securing the name tag envelope, allowing for easy assembly and secure attachment without the need for complex clamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex multi-component lanyard devices are used, then secure attachment is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functional components (link, clamps, folding mechanisms) into a single integrated one-piece structure made from polymer material. This merging eliminates the need for separate components while maintaining the secure attachment function through integrated folding clamps that lock the lanyard in place.
Solution Approach 2:
The one-piece device performs multiple functions: it acts as a link connector, incorporates folding clamps for securing the lanyard, and includes integrated fastening mechanisms. This multi-functionality replaces what would traditionally require multiple separate components, reducing overall device complexity.
2Reliability
If traditional lanyard devices are used, then securement function is achieved, but environmental impact increases due to non-biodegradable materials
Solution Approach 1:
The patent changes the material parameter from traditional non-biodegradable materials to biodegradable polymer materials. This parameter change maintains the mechanical functionality and securement capability of the device while eliminating the environmental harm associated with persistent waste from conventional lanyard devices.
3Strength
If thick polymer material is used for the link, then structural strength is achieved, but ease of folding and manipulation decreases
Solution Approach 1:
The patent optimizes the thickness parameter of the polymer material to achieve a balance between structural strength and foldability. The thickness is sufficient to provide the necessary strength for securing the lanyard but thin enough to allow easy folding and manipulation of the clamps and links during assembly and use.
