Adjustable Firewall Bracket for Wiper and Water Box Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing functional elements like window wipers, water boxes, and electrical connectors on a motor vehicle's transverse heating partition require multiple separate fixing parts and tools, leading to increased manufacturing time, tool requirements, and variability across different vehicle models.
Innovation Solution
A single, elongated fixing support with three integrated fixing elements for the windshield wiper, water box, and electrical connector, featuring adjustable means to align and secure these elements to the heating partition, reducing the need for multiple tools and parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate fixing parts are used for each functional element, then each element can be fixed independently, but the number of fasteners and tools increases, and manufacturing time is extended
Solution Approach 1:
The patent combines multiple separate fixing parts into a single integrated fixing support structure that can simultaneously secure the windscreen wiper, water box, and electrical connector. This merging reduces the total number of fasteners and tools needed while maintaining the ability to fix each functional element independently through dedicated mounting points on the unified structure.
2Adaptability or versatility
If multiple separate fixing parts are used for each functional element, then each element can be fixed independently, but the number of tools required increases
Solution Approach 1:
The fixing support integrates multiple fixing functions into a single structural component with built-in mounting points for each functional element. This eliminates the need for multiple separate tools to install each element individually, as the unified structure can be secured using a single tool or tool set, thereby reducing device complexity while preserving independent fixing capability.
3Adaptability or versatility
If multiple separate fixing parts are used for each functional element, then customization for different vehicle models is possible, but variability across models increases
Solution Approach 1:
The fixing support is designed as a universal multi-functional component that can accommodate different functional elements (windscreen wiper, water box, electrical connector) and adapt to various vehicle models. The standardized design with multiple mounting points allows the same fixing support structure to be used across different models, reducing variability while maintaining the ability to customize configurations for specific vehicle requirements.
4Reliability
If three individual fasteners are manufactured and handled for each vehicle, then each element can be secured separately, but the assembly process becomes time-consuming
Solution Approach 1:
The patent merges three separate fastening operations into a single assembly step by providing an integrated fixing support that secures all three functional elements simultaneously. This reduces the assembly process from handling three individual fasteners to installing one unified component, thereby maintaining secure fixation while significantly reducing assembly time and the number of interventions required.
