Solution Overview
Problem
There is a need for a simple, inexpensive, and efficient method to mount a power relay box of a fan motor assembly in a motor vehicle engine compartment, as existing solutions lack support for the weight of the case in the new designated position.
Innovation Solution
A fixing device with at least one first and second pinching means that act on ribs of the structure, positioned to form an acute angle greater than 30°, preferably a right angle, using staples that deform to create frictional forces for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power relay box is moved to a position close to the fan motor assembly, then the spatial arrangement and accessibility are improved, but there is no structural element available to support the weight of the case
Solution Approach 1:
The fixing device is divided into multiple independent fixing means (at least two) that can be distributed across different structural elements. Each fixing means independently contributes to supporting the weight, distributing the load rather than relying on a single support point. This segmentation allows the device to adapt to positions with limited structural support while maintaining adequate weight-bearing capacity.
Solution Approach 2:
The invention transitions from relying on vertical support (single dimension) to utilizing multiple spatial dimensions for support. By positioning at least two fixing means at different locations and orientations, the device creates a multi-dimensional support structure that can anchor to the structure in various directions, effectively distributing weight across multiple structural elements rather than requiring a single strong support point.
2Strength
If a complex fixing device with multiple support elements is used, then the weight support capacity is improved, but the assembly becomes more complicated and time-consuming
Solution Approach 1:
Multiple fixing means are merged into a single integrated fixing device that acts as one unified component. This consolidation allows the device to provide multi-point support (distributing weight across multiple locations) while maintaining simple installation procedures. The merged structure eliminates the need to install separate support elements individually, reducing assembly complexity despite the increased functional capability.
Solution Approach 2:
The fixing device is designed with multi-functionality, serving both as a mounting mechanism and a weight support structure simultaneously. By integrating multiple fixing means into one device, it performs the dual function of securing the power relay box to the structure while distributing its weight load. This universal design eliminates the need for separate support brackets or additional structural modifications, simplifying the overall assembly process.
3Device complexity
If traditional fixing methods are used without positioning means, then the device structure is simpler, but the assembly precision and orientation are compromised
Solution Approach 1:
Positioning means are integrated into the fixing device to pre-establish the correct spatial relationship and orientation between fixing means and the structure before final attachment. This preliminary positioning action ensures that when the fixing device is installed, the fixing means are already correctly aligned with their target locations on the structure, achieving high assembly precision without requiring complex adjustment procedures or multiple installation steps.
