Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for vehicle components, such as exciters, face challenges in achieving reliable and efficient vibration transfer while meeting acoustic, durability, and operational requirements, including visibility, structural interference, and ease of installation and servicing.
Innovation Solution
A mounting system comprising a locking mount with a base and collar, secured to the interior surface of a vehicle body panel using a structural patch, which allows for positive contact with the exciter, enabling efficient vibration transfer and acoustic performance without visible attachments or structural interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting system is designed to achieve reliable vibration transfer, then acoustic performance is improved, but the complexity of the mounting system increases
Solution Approach 1:
The mounting system is divided into distinct functional components: a mounting plate for attachment to the body panel, a locking mechanism with cam tab and flange engagement for secure positioning, and a structural patch for reinforcement. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability for vibration transfer.
Solution Approach 2:
The mounting system transitions from a simple surface attachment to a three-dimensional locked engagement. The collar extends outward from the mounting plate, and the flange with lip engages the cam tab in a perpendicular direction, creating a multi-dimensional connection that enhances vibration transfer reliability without proportionally increasing complexity.
2Object-affected harmful factors
If the mounting system uses visible attachments on the exterior surface, then structural interference is reduced, but aesthetic appearance deteriorates
Solution Approach 1:
The critical structural engagement features (locking mechanism, cam tab engagement) are extracted and positioned on the interior surface of the body panel. The exterior surface only requires a small mounting plate, eliminating the need for visible exterior attachments while maintaining structural interference-free design.
Solution Approach 2:
Instead of mounting components from the exterior surface, the system inverts the mounting approach by attaching the mounting plate to the interior surface. This reversal allows the locking mechanism to engage from inside the panel, keeping all substantial attachments hidden from exterior view while maintaining structural integrity.
3Ease of operation
If the mounting system is designed for easy installation and servicing, then ease of operation is improved, but mounting reliability may deteriorate
Solution Approach 1:
The locking mechanism incorporates a dynamic cam tab that can be engaged and disengaged through rotational motion. During installation, the cam tab is inserted and rotated to lock the flange in place. For servicing, the same rotational motion releases the lock. This dynamic mechanism provides both ease of operation and reliable mounting through positive mechanical engagement.
Solution Approach 2:
The mounting system is designed to be self-locating and self-locking. The flange with lip automatically engages the cam tab when properly positioned, and the structural patch self-adheres to reinforce the mounting area. This self-service design simplifies installation while ensuring reliable mounting without requiring complex adjustment procedures.
