Vehicle Seat Guide Device One-Piece Stop Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat adjustment systems face challenges in individually limiting the maximum adjustment path in both directions without increasing costs, as they often require additional components and complex assembly, which can lead to collisions and discomfort due to fixed adjustment limits.
Innovation Solution
A guide device with a one-piece component, divided into two sections, is introduced, which can be easily integrated into standard ball rail systems to limit adjustment paths in both directions, allowing for flexible adjustment without altering the existing assembly, enabling easy retrofitting and cost-effective customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate components are used to limit adjustment path in both directions, then the adjustment path can be limited in both directions, but the assembly complexity and costs increase significantly
Solution Approach 1:
The patent combines two separate stop-limiting components into a single integrated component that can limit the adjustment path in both forward and backward directions. This one-piece component includes multiple stop surfaces that interact with corresponding stop elements on the rail device, eliminating the need for separate components and reducing assembly complexity while maintaining bidirectional adjustment path limitation capability.
2Ease of manufacture
If standard bought-in parts are used for rail equipment, then costs are reduced, but individual customization of adjustment path limits becomes expensive
Solution Approach 1:
The integrated component is designed with segmented functional areas - different stop surfaces can be positioned at different locations along the component length. This allows the component to be manufactured as a single piece using cost-effective standard processes, while the positioning of stop surfaces can be individually adjusted or selected to meet specific customization requirements for different applications.
Solution Approach 2:
The single component serves multiple functions: it limits adjustment path in both directions, provides multiple stop positions, and can be configured for different customization needs. This multi-functional design allows standard manufacturing methods to be used while still enabling individual customization of adjustment path limits without requiring expensive specialized production.
3Adaptability or versatility
If maximum adjustment path is extended to accommodate all users, then adaptability improves, but collisions with vehicle components occur
Solution Approach 1:
The component proactively prevents harmful collisions by incorporating stop surfaces that limit the adjustment path before the seat can move into positions that would cause collisions with vehicle components such as windows or the steering wheel. This preliminary restriction of movement range eliminates the collision risk while still providing sufficient adjustment range for user comfort.
