Vehicle Monitor Base Assembly With Stopper-Guided Cover Edge Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base assemblies for vehicle periphery monitoring devices face challenges in restricting the edge of the cover from moving with respect to the base, which affects the appearance and functionality of the device.
Innovation Solution
The base assembly includes a base, gasket, and cover with specific stopper parts designed to restrict the vertical edge of the cover from moving, utilizing a combination of horizontal and vertical edge parts and protrusions to prevent movement, ensuring the cover remains fixed in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cover is attached to the base without stopper parts, then the device complexity is reduced, but the edge of the cover moves with respect to the base, spoiling the appearance
Solution Approach 1:
The stopper parts are integrally formed with the base and cover through injection molding, allowing the components to self-restrict movement without additional fastening mechanisms. The stopper protrusions and stopper grooves automatically engage to prevent edge displacement, eliminating the need for separate retaining elements.
Solution Approach 2:
Instead of providing uniform fastening across the entire cover-base interface, stopper parts are strategically placed only at the edge portions where movement occurs. This localized approach prevents edge displacement while maintaining simplicity in the central attachment areas.
2Stability of the object's composition
If stopper parts are added to restrict edge movement, then the edge position stability is improved, but the device complexity increases
Solution Approach 1:
The stopper parts are merged with the base and cover as integral components formed through injection molding. The stopper protrusions are formed directly on the base, and the stopper grooves are formed directly on the cover, combining multiple functions into single components without requiring separate parts or assembly steps.
Solution Approach 2:
The stopper structures serve dual purposes: the protrusions and grooves simultaneously provide positioning and preventing edge displacement. The design allows the components to self-restrict movement through their own geometric features without requiring additional fastening mechanisms or assembly operations.
3Adaptability or versatility
If the dimensions between the base and cover are increased for design flexibility, then the adaptability is improved, but the edge of the cover becomes more prone to movement
Solution Approach 1:
The attachment interface is segmented into multiple independent stopper pairs distributed around the perimeter. This segmentation allows each stopper to independently control edge position, enabling larger overall dimensions while maintaining stability through distributed constraint points rather than a single rigid connection.
