Hinger HTR Tube Bracket Spacer Mechanism
Solution Overview
Problem
Current fastening elements for motor vehicle air conditioning systems require additional components to maintain the distance between fluid conduit ends aligned one behind the other, increasing complexity and cost.
Innovation Solution
A fastening element with a U-shaped clamping region and a pivotable spacer connected via a film hinge, allowing the spacer to fill and bridge the clamping region, acting as a spacer between conduit ends aligned perpendicularly, reducing the need for additional components and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an additional spacer component is used to maintain distance between conduit ends, then the distance between conduit ends can be ensured, but the device complexity and cost increase
Solution Approach 1:
The patent integrates the spacer function directly into the fastening element by forming a recess in the clamping region that can receive a spacer component. This merging of functions eliminates the need for separate spacer components when conduits are arranged one behind the other, reducing overall device complexity while maintaining precise spacing control between conduit ends
Solution Approach 2:
The clamping region is segmented into multiple functional zones including the clamping surface and a recess area. This segmentation allows the same fastening element to accommodate different conduit arrangements (side-by-side or one-behind-another) by selectively using the recess for spacing when needed, while maintaining simple clamping functionality when not needed
2Ease of operation
If the mounting direction is parallel to the alignment of conduit ends, then the fastening element can be mounted, but an additional spacer component is required to position the conduit ends
Solution Approach 1:
The fastening element is designed with universal functionality to handle both mounting directions (perpendicular and parallel to conduit alignment) and both conduit arrangements (side-by-side and one-behind-another). The recess in the clamping region provides spacing capability when conduits are arranged one behind the other during parallel mounting, while the same structure serves as a simple clamping region for perpendicular mounting, eliminating the need for different components for different configurations
