Vehicle Fastening Layout That Avoids Cover Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening devices in motor vehicles, such as those used to secure hoses or cables to an air filter box, often obstruct the cover or become wedged between components due to limited installation space, making mounting and dismounting difficult.
Innovation Solution
A fastening device with a flexibly bendable component and a receiving means that allows the second component to be moved along a joining direction without colliding with the fastening means, ensuring that the receiving portion and fixing means are spaced from the second component by a gap, preventing contact and obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners are located in the joining area of the air filter box, then the fastening function is achieved, but the cover is obstructed during installation or the fastener becomes wedged between the cover and the air filter housing
Solution Approach 1:
The fastening device is extracted from the joining area and relocated to the outer surface of the air filter housing adjacent to the joining region. The receiving means is fixed to the outer surface while the fastening means extends beyond the joining region, separating the fastening function from the joining area to eliminate obstruction during cover installation and removal
Solution Approach 2:
The fastening device transitions from a two-dimensional planar arrangement within the joining area to a three-dimensional configuration where the receiving means is mounted on the outer surface and the fastening means extends beyond the joining region in the direction opposite to the joining direction, creating spatial separation that prevents interference with the cover
2Reliability
If the fastening device is located in the joining area, then the fastening function is achieved, but the installation space is limited and the fastener becomes trapped between components
Solution Approach 1:
The fastening device is extracted from the constrained joining area and repositioned on the outer surface of the air filter housing, eliminating the problem of the fastener becoming trapped between the cover and housing while maintaining the fastening function through the receiving means and fastening means configuration
Solution Approach 2:
The fastening device is segmented into distinct functional components: the receiving means fixed to the outer surface, the fastening means extending beyond the joining region, and the coupling section. This segmentation allows each component to perform its function independently without interference, simplifying the overall installation process
3Reliability
If the receiving portion and fastening means are close to the joining region, then the fastening function is achieved, but the second component collides with the fastening device during mounting
Solution Approach 1:
The receiving means is positioned on the outer surface of the air filter housing with the fastening means extending beyond the joining region in the direction opposite to the joining direction. This three-dimensional positioning creates a gap between the fastening device and the second component during assembly, allowing smooth installation without collision while maintaining effective fastening
