Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat pitching spring units require a significant space due to their complex configuration, making them difficult to implement effectively in vehicle seating systems.
Innovation Solution
A vehicle seat design utilizing a scissor frame arrangement with a spring element carrier connected to first and second scissor arms, allowing for rotational movement and minimizing structural connections between the arms, thereby simplifying the configuration and enabling efficient pitching and vertical movements while maintaining a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional pitching spring unit is used, then the pitching function is achieved, but the space requirement in X-direction and Y-direction increases significantly
Solution Approach 1:
The patent combines the pitching spring unit with the scissor frame arrangement by integrating the spring element carrier directly into the scissor arm structure. The spring element carrier is connected to the scissor arms at their crossing region, merging the pitching mechanism with the height adjustment mechanism into a single integrated structure that performs both functions without requiring separate space for each system.
Solution Approach 2:
The scissor frame arrangement serves multiple functions: it provides height adjustment capability while simultaneously serving as the mounting structure for the pitching spring unit. The spring element carrier, integrated into the scissor arm crossing region, enables pitching motion while the scissor arms themselves handle vertical displacement, creating a multi-functional system that reduces overall space requirements.
