Trailer Connection Housing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for trailer vehicles require complex and costly individual mounting of multiple connections, leading to increased assembly effort and manufacturing costs.
Innovation Solution
A connection arrangement where multiple connections (electrical and pneumatic) are integrated onto a single housing unit, with the housing itself forming part of the connections, reducing the number of elements needed and allowing for easier assembly and reduced manufacturing costs by using fastening means like bores or threads, and optionally molded components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple connections are mounted individually on metal carriers, then each connection can be separately installed and maintained, but the assembly complexity and manufacturing costs increase significantly
Solution Approach 1:
The patent combines multiple separate connections (electrical sockets, pneumatic coupling heads) into a single integrated housing unit. This merging reduces the number of separate mounting operations required and simplifies the overall assembly process, directly addressing the technical contradiction by reducing assembly effort while managing device complexity through functional integration.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support, houses electrical connections, accommodates pneumatic connections, and provides mounting interfaces. This multi-functionality allows a single component to replace what would traditionally require multiple separate elements, thereby reducing assembly complexity while maintaining the necessary functionality of each connection type.
2Productivity
If connections are mounted individually on separate carriers, then each connection can be independently accessed, but the installation time and labor costs increase
Solution Approach 1:
By merging multiple connections into a single housing unit, the patent enables all connections to be installed simultaneously in one operation rather than requiring separate mounting operations for each connection. This directly improves assembly speed and reduces the time loss associated with multiple individual installation steps.
Solution Approach 2:
The connections are pre-integrated into the housing during manufacturing, so that during installation, the entire assembly of connections arrives pre-configured and ready for mounting. This preliminary integration eliminates the need for on-site assembly of individual connections, thereby reducing installation time and improving productivity.
3Ease of manufacture
If multiple separate mounting elements are used, then each connection can be securely fixed, but the manufacturing costs and material usage increase
Solution Approach 1:
The patent merges multiple separate mounting elements into a single housing structure, reducing the total quantity of components required. This consolidation directly reduces manufacturing costs by eliminating the need to source, stock, and assemble multiple separate mounting elements, while still providing secure fixation for all connections through the integrated housing design.
