Headlamp Washer Fixing Assembly Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp washer fixing assemblies require additional fastening elements and complex installation processes, increasing production costs and reducing recyclability, while also facing issues with durability and vibration resistance over time.
Innovation Solution
A fixing assembly that uses snap-in lugs and a cantilevered support structure, eliminating the need for additional fastening elements and installation steps, and ensuring durable maintenance by transmitting forces and vibrations directly to the vehicle body through a support leg and connecting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional fastening elements (screws, clips, welds) are used to secure the headlamp washer support, then the fixing strength and vibration resistance are improved, but the device complexity and installation steps increase
Solution Approach 1:
The support structure is merged with the base structure to form an integrated cantilevered assembly. The support and base are designed as a single structural unit that eliminates the need for separate fastening elements, while maintaining fixing strength through the integrated design and bearing zones.
Solution Approach 2:
Traditional fastening elements (screws, clips, welds) are extracted/removed from the assembly. The invention achieves fixing without these additional components by using the cantilevered support structure with bearing zones that directly interface with the bodywork opening.
2Reliability
If additional fastening elements and installation steps are used, then the fixing reliability is improved, but the productivity and manufacturing efficiency decrease
Solution Approach 1:
The support and base are pre-configured with integrated bearing zones and geometric features during manufacturing. This preliminary action ensures that during installation, the structure automatically positions itself correctly against the bodywork opening without requiring additional fastening steps, maintaining reliability while improving productivity.
3Stability of the object's composition
If permanent fastening means (welds, glue) are used, then the vibration resistance is improved, but the recyclability and ease of disassembly worsen
Solution Approach 1:
The fixing system transitions from static permanent connections (welds, glue) to a dynamic mechanical interface using the cantilevered support with bearing zones. This allows the structure to accommodate vibrations through natural movement while maintaining stability, and enables easy disassembly for recycling without permanent damage.
4Ease of manufacture
If the support structure is simplified to eliminate fastening elements, then the ease of manufacture is improved, but the ability to resist vibrations and maintain position worsens
Solution Approach 1:
The support structure incorporates locally optimized bearing zones at specific contact points with the bodywork opening. These localized features concentrate the load-bearing functionality where needed, maintaining position maintenance capability while keeping the overall structure simple and easy to manufacture without complex fastening elements.
