Rigid Window Regulator Assembly for Robotic Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window regulators in vehicles are challenging to install using automated processes due to the flexible nature of their components, which makes it difficult for robots to grasp and position guide rails accurately.
Innovation Solution
A rigid window regulator system with fixed guide rails connected by a cross-brace assembly, allowing for automated installation using robotic arms, and detachable or permanent cross-brace connections for efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional window regulators are designed for manual installation, then they allow for flexible assembly by human operators, but they cannot be efficiently installed by robotic assembly processes
Solution Approach 1:
The window regulator assembly transitions from a flexible, manually-assembled configuration to a rigid, pre-assembled unit that can be gripped and positioned by robotic arms. The cross-brace assembly provides structural rigidity that enables automated handling while maintaining the functional flexibility of the regulator system during operation.
Solution Approach 2:
The window regulator is divided into separable components (guide rails, cross-brace assembly, window pane) that can be pre-assembled into a rigid structure for automated installation, then installed as a complete unit by robotic systems, resolving the contradiction between manual flexibility and automated efficiency.
2Manufacturing precision
If guide rails are made rigid and connected by cross-brace assembly, then precise alignment is achieved for automated installation, but device complexity increases
Solution Approach 1:
Multiple guide rails and cross-brace members are merged into a single rigid assembled unit that provides precise alignment for automated installation. The cross-brace assembly combines structural support and alignment functions into one integrated component, reducing the need for separate alignment mechanisms.
3Stability of the object's composition
If multiple cross-brace members are used to rigidly connect guide rails, then structural stability is improved, but assembly time increases
Solution Approach 1:
The cross-brace assembly and guide rails are pre-assembled into a rigid, stable structure before installation. This preliminary assembly ensures structural stability is achieved in advance, allowing the complete unit to be installed quickly by robotic systems without requiring time-consuming on-site assembly of multiple cross-brace members.
