Guide Rail Integrated Fastening for Vehicle Adjusting Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjusting devices for vehicle parts require complex and costly assembly processes, including separate fastening brackets that increase material and assembly costs, and complicate the connection process, especially during load conditions like crashes.
Innovation Solution
The use of structurally separated supporting parts welded directly to the guide rail, eliminating the need for screw connections and simplifying assembly by positioning the adjusting mechanism between these supporting parts, which are form-locked and thermally bonded for secure support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening bracket with screw connections is used to connect the adjusting mechanism to the guide rail, then the connection provides secure support under load, but the assembly process becomes complex and costly
Solution Approach 1:
The patent merges the fastening bracket and the guide rail into a single integrated component. The guide rail is designed with built-in supporting parts that directly support the adjusting mechanism, eliminating the need for separate fastening brackets and screw connections. This integration simplifies the assembly process while maintaining connection integrity through the unified structural design.
Solution Approach 2:
The patent extracts the fastening bracket as a separate component and eliminates it from the assembly. Instead, the guide rail itself is designed to provide the supporting function directly through integrated supporting parts, removing the unnecessary intermediate fastening element and simplifying the overall structure.
2Adaptability or versatility
If multiple separate components (fastening bracket, adjusting mechanism, guide rail) are used, then each component can be optimized independently, but the material costs and assembly time increase
Solution Approach 1:
The patent combines the guide rail and fastening bracket functions into a single integrated guide rail structure. The supporting parts are built into the guide rail itself, reducing the number of separate components from three (guide rail, fastening bracket, adjusting mechanism) to two (integrated guide rail, adjusting mechanism), thereby increasing assembly speed while preserving design flexibility.
3Reliability
If conventional fastening brackets are used, then the adjusting mechanism is securely retained, but the overall device weight and material consumption increase
Solution Approach 1:
The patent merges the fastening function into the guide rail structure itself. The supporting parts are integrated into the guide rail, eliminating the need for additional fastening bracket material. This reduces overall material consumption while maintaining retention security through the structurally sound integrated design.
