Vehicle Head Unit Mounting Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual insertion of connectors into head units in vehicles is inefficient, leading to increased vehicle weight, potential damage to optical cables, connection errors, and prolonged assembly time due to the need for excess cable length and reliance on human precision.
Innovation Solution
A mounting frame assembly that houses pre-positioned connector assemblies and uses a manually operable lever to apply a pressing force, guiding the head unit into place, ensuring proper connector alignment and connection, with adjustable pins for centering and easy disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion of connectors is used, then assembly flexibility is maintained, but assembly time increases and productivity decreases
Solution Approach 1:
The connector assemblies are pre-positioned in the mounting frame assembly before the head unit is inserted. This preliminary arrangement of connectors eliminates the need for manual insertion during assembly, thereby reducing assembly time and increasing productivity while maintaining flexibility through the modular frame design.
2Ease of operation
If excess cable length is used, then ease of connection is improved, but vehicle weight increases
Solution Approach 1:
The mounting frame assembly pre-positions connector assemblies at their final destinations before head unit installation. This allows cables to be routed optimally without requiring excessive length for manual maneuvering, reducing vehicle weight while maintaining ease of connection through the guided insertion process.
3Manufacturing precision
If manual connector insertion is used, then adaptability is maintained, but connection precision decreases and errors increase
Solution Approach 1:
The mounting frame assembly acts as an intermediary structure that holds connector assemblies in precise positions. The frame's guide structures and the interaction between the first fixing means and second fixing means ensure accurate connector alignment, eliminating human error while maintaining operational simplicity through the lever-based insertion mechanism.
4Volume of moving object
If optical cables are bent with small curvature radius, then space utilization is improved, but cable reliability decreases
Solution Approach 1:
The mounting frame assembly pre-positions connector assemblies with adequate spacing and routing paths that ensure optical cables maintain sufficient bend radius. This preliminary spatial arrangement prevents cable damage while achieving compact space utilization through optimized connector placement within the frame structure.
