Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat shells for vehicles are difficult to produce and install, and the attachment or replacement of seat cushions is not straightforward, lacking in ease of use and flexibility.
Innovation Solution
A seat shell design featuring a profile element with hollow areas and a web-shaped connecting area, allowing for flexibility and stability while reducing mass, with guide elements for easy cushion attachment and recesses for weight reduction, formed in one piece for efficient production and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a seat shell is constructed with hollow profile areas and connecting areas, then weight is reduced and flexibility is improved, but structural complexity increases
Solution Approach 1:
The profile element is divided into distinct functional areas: hollow profile areas for weight reduction and flexibility, web-shaped connecting areas for structural stability, and guide elements for cushion attachment. This segmentation allows each area to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
Different regions of the profile element have different structural properties tailored to their specific functions. The hollow profile areas provide flexibility and weight reduction where needed, while the web-shaped connecting areas provide rigidity and stability where structural support is required. This local differentiation of structural quality resolves the contradiction between weight reduction and structural complexity.
2Productivity
If the profile element is formed in one piece in the longitudinal direction, then production efficiency is improved and manufacturing complexity is reduced, but the ability to attach and replace seat cushions becomes more difficult
Solution Approach 1:
While the profile element itself is formed as a single piece for production efficiency, the seat cushion is designed as a separate, detachable component. The guide elements in the profile element provide standardized attachment points that enable easy coupling and decoupling of the cushion, thus maintaining productivity while improving ease of operation for cushion replacement.
Solution Approach 2:
The guide elements act as intermediary structures that facilitate the connection between the monolithic profile element and the detachable seat cushion. These guide elements provide a standardized interface that enables easy attachment and replacement of cushions without compromising the integrity of the one-piece profile structure.
3Ease of operation
If guide elements are added to the profile element for cushion attachment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The guide elements are integrated directly into the profile element structure during the extrusion process, merging the attachment function with the structural framework. This combination approach improves ease of cushion attachment while minimizing the increase in device complexity, as the guide elements become an inherent part of the profile element rather than separate additions.
