Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular seat assembly methods require a large number of components and are costly, with complex and labor-intensive assembly processes due to the use of screws, nuts, and hard resin plates.
Innovation Solution
A vehicular seat design featuring a surface skin with a first and second surface skin connected via a soft material, such as an elastomer, where the second surface skin is stitched to the first and has protruding members that fit into holes on the base, reducing the number of components and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws, nuts, and hard resin plates are used to fix the surface skin to the frame, then the attachment strength is improved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The invention merges the attachment function into the surface skin itself by forming protrusions directly on the surface skin that engage with recesses in the frame. This eliminates the need for separate screws, nuts, and hard resin plates, reducing the number of components while maintaining attachment strength through the integrated design.
Solution Approach 2:
The invention changes the material parameter of the surface skin from conventional non-elastic materials to elastic material. This parameter change enables the surface skin to deform during assembly and secure itself to the frame through the elastic protrusions, eliminating the need for multiple fastening components.

This eliminates the need for separate screws, nuts, and hard resin plates, reducing the number of components while maintaining attachment strength through the integrated design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design significantly reduces component count and assembly complexity, lowering costs and making the process easier, while maintaining the shape-retaining properties of the soft material for secure attachment.
Implementation Method 1
The soft material is an elastomer, a soft resin, a molded non-woven cloth, a similar material, or a combination thereof. The elastomer is a rubbery and elastic industrial material.
