Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment clips for spoiler systems often fail to securely hold pins due to poor design, leading to squeak and rattle issues, vibration-induced deformation, and potential breakage, which compromises driving comfort and vehicle stability.
Innovation Solution
An attachment clip with flexible side walls and an elastic element, such as a sponge, that provides a positive fit for the pin, absorbing vibrations and preventing movement, while a U-shaped design with additional structural features enhances stiffness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic attachment clip is used to hold the pin, then the spoiler system can be assembled, but the pin cannot be held tightly leading to movement and clearance
Solution Approach 1:
An elastic element is integrated into the attachment clip to provide beforehand cushioning for the pin. This elastic element absorbs vibrations and prevents clearance formation before harmful squeak and rattle noises can occur, thereby improving pin holding stability and eliminating noise issues.
Solution Approach 2:
The attachment clip combines plastic material with an elastic element to create a composite structure. This composite design integrates the structural properties of plastic with the vibration-absorbing properties of the elastic element, simultaneously achieving secure pin holding and noise reduction.
2Ease of manufacture
If the plastic attachment clip is designed with simple structure, then manufacturing is easy, but it cannot absorb vibrations during vehicle travelling
Solution Approach 1:
The elastic element is pre-integrated into the attachment clip structure to provide vibration absorption before vibration damage can occur. This beforehand cushioning protects the pin and surrounding components from vibration-induced deformation and micro cracks during vehicle travelling.
Solution Approach 2:
The elastic element acts as an intermediary between the rigid plastic clip and the pin, mediating the transmission of vibrations. It absorbs and dampens vibrations before they can transmit to the pin and cause harmful effects, while maintaining the simplicity of the overall attachment mechanism.
3Ease of operation
If the attachment clip is made of flexible plastic material, then it can be easily assembled, but it deforms due to applied forces from repeated operations
Solution Approach 1:
The combination of plastic and elastic element creates a composite attachment clip that maintains the ease of assembly of plastic while adding vibration absorption and structural reinforcement. This composite structure prevents deformation from repeated operations.
Solution Approach 2:
The elastic element introduces a curved, flexible component into the attachment mechanism that can deform elastically under load and return to its original shape. This curvature allows the structure to accommodate repeated assembly operations without permanent deformation or failure.
4Device complexity
If the attachment clip has basic design, then device complexity is low, but micro cracks grow causing plastic parts to split
Solution Approach 1:
The elastic element provides beforehand cushioning that absorbs vibrations before they can create stress concentrations that lead to micro crack formation. This prevents the progressive damage that would otherwise cause part splitting while maintaining relatively simple overall design.
Solution Approach 2:
The introduction of the elastic element changes the mechanical parameters of the attachment clip, specifically adding vibration damping capability and improving stress distribution. This parameter change enhances part integrity without significantly increasing design complexity.
