Disposable Elastomer Coil Reducing Transport Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transporting and processing elastomer strands are inefficient due to the use of heavy, durable materials that increase transport costs and require costly return trips for empty coils, limiting the utilization of transport space and material resilience.
Innovation Solution
A device utilizing lighter materials like foam, cardboard, and recycled plastic for the coil and packaging, with a form-fit and force-fit connection between the ring element, coil core, and end wall parts, allowing for easier disposal and reduced material costs, while maintaining transport and production safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy durable materials are used for the coil, then transport safety and production reliability are improved, but transport costs increase and return trips are required
Solution Approach 1:
The coil is divided into multiple functional parts with different material requirements: the ring element (connection component) is made of durable material for reliability, while the coil core and end pieces (bulk components) are made of lightweight disposable material to reduce weight and cost
Solution Approach 2:
Different parts of the coil have different material properties tailored to their specific functions: the ring element requires high strength for connection reliability, while the coil core and end pieces can use lightweight materials since they only need to hold the elastomer strand
2Weight of moving object
If lightweight disposable materials are used for the coil, then transport costs are reduced and disposal is simplified, but transport and production safety may be compromised
Solution Approach 1:
The coil structure is segmented into critical connection parts (ring element) and non-critical bulk parts (coil core, end pieces), allowing lightweight materials to be used where safety is not compromised while maintaining overall reliability through durable connection components
Solution Approach 2:
The coil uses a composite construction combining different material types: durable material for the ring element and lightweight disposable material for the coil core and end pieces, optimizing both weight and reliability
3Loss of substance
If the coil is designed for return trips to the manufacturer, then material utilization is improved, but transport volume efficiency decreases
Solution Approach 1:
The coil is designed as a disposable component made primarily of lightweight cardboard and foam materials, eliminating the need for return trips and allowing optimal transport volume utilization, with only the small ring element requiring recycling
