Window Lifter Assembly Reinforcement Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of window lifter assemblies for vehicle windows is complex due to the need for separate mounting of reinforcement members, which complicates the integration of guiding elements and increases the risk of misalignment and assembly errors.
Innovation Solution
A window lifter assembly design where a reinforcement member, made of a different material than the carrier member, is at least partially embedded in the plastic material of the carrier member, forming a form-fit connection that integrates the reinforcement member as an integral part of the carrier, eliminating the need for separate assembly and enhancing structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a separate reinforcement member is mounted to the carrier member, then structural support at the guiding element mounting region is improved, but assembly complexity increases
Solution Approach 1:
The reinforcement member and carrier member are merged into a single integrated component. The reinforcement member is embedded within the carrier member during the molding process, creating a unified structure that provides both structural support and simplifies assembly by eliminating separate mounting operations.
Solution Approach 2:
The reinforcement member is pre-positioned and embedded in the carrier member during the molding process before final assembly. This preliminary integration ensures proper alignment and structural support is already in place, eliminating the need for separate mounting steps and reducing assembly complexity.
2Stability of the object's composition
If a separate reinforcement member with fastening elements is used, then structural integrity is improved, but the risk of misalignment and assembly errors increases
Solution Approach 1:
By merging the reinforcement member and carrier member into a single integrated component during molding, the patent eliminates the interfaces between separate parts. This ensures perfect alignment and structural integrity without the risks of misalignment that accompany separate fastening operations.
Solution Approach 2:
The molding process itself automatically positions and integrates the reinforcement member in the correct location and orientation. The process self-corrects any alignment issues that would occur with manual assembly, ensuring manufacturing precision without requiring additional alignment procedures.
3Adaptability or versatility
If multiple separate components are assembled, then adaptability is improved, but assembly time and productivity are reduced
Solution Approach 1:
The patent combines multiple components (carrier member and reinforcement member) into a single integrated part through embedding during molding. This reduces the number of assembly steps and increases productivity, while the modular design of the integrated component maintains adaptability for different applications.
