Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat assemblies are not environmentally friendly and are difficult to disassemble for recycling, lacking structural soundness and comfort.
Innovation Solution
A vehicle seat assembly comprising a structural layer, a soy-based foam cushion layer, and a comfort pad, all secured with a trim material that allows for easy separation and recycling, using materials like expanded polyolefin and soy-based polyurethane foam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional base construction polymers are mixed and joined in a difficult-to-disassemble manner, then structural strength and durability are improved, but environmental friendliness and recyclability deteriorate
Solution Approach 1:
The seat assembly is divided into distinct layers (structural layer, cushion layer, trim material) that can be easily separated for recycling. Each layer maintains its integrity while allowing disassembly, resolving the contradiction between structural strength and recyclability.
Solution Approach 2:
The patent uses composite material construction with a structural layer made of recyclable polymers, a cushion layer of foam material, and a trim material layer. These composite layers are designed to work together structurally while being separable for environmental recycling purposes.
2Stability of the object's composition
If conventional seat assemblies use difficult-to-disassemble construction, then structural soundness is improved, but ease of disassembly for recycling deteriorates
Solution Approach 1:
The seat assembly is segmented into distinct functional layers (structural layer, cushion layer, trim material) that are easily separable. This segmentation maintains structural soundness during use while enabling simple disassembly for recycling by pulling the trim material over the cushion composite.
3Object-affected harmful factors
If environmentally friendly materials are used with easy separation design, then recyclability is improved, but structural strength and comfort may deteriorate
Solution Approach 1:
The patent employs composite materials where the structural layer provides necessary strength and support, the cushion layer provides comfort, and the trim material provides durability. This composite structure achieves both structural integrity and environmental friendliness through material selection and layered design.
Solution Approach 2:
By segmenting the seat into functional layers with distinct materials optimized for their specific purposes, the design maintains structural strength in the structural layer while enabling easy recycling through simple separation of layers.
