Vehicle Monitoring Base Assembly With Interlocking Cover Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base assemblies for vehicle periphery monitoring devices struggle to effectively restrict the edge of the cover from moving with respect to the base, which can lead to a spoiled appearance and potential mechanical issues.
Innovation Solution
The base assembly incorporates stopper parts on both the cover and base sides, featuring plate parts, abutting edge parts, and protrusions that interlock to prevent vertical edge movement, ensuring stability and appearance integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cover is assembled to the base without additional restraint mechanisms, then the assembly process is simple, but the edge of the cover can move with respect to the base causing appearance degradation
Solution Approach 1:
The restraint function is segmented into multiple independent stopper parts: a first stopper part on the cover and a second stopper part on the base. This segmentation allows each component to be manufactured separately and assembled easily, while collectively providing comprehensive restraint against cover edge movement in multiple directions.
Solution Approach 2:
The stopper parts act as intermediary elements between the cover and base. The first stopper part protrudes from the cover and engages with the second stopper part on the base, creating an intermediate restraint mechanism that prevents direct movement between the cover edge and base while maintaining assembly simplicity.
2Stability of the object's composition
If stopper parts are added to restrict cover edge movement, then the stability and appearance are improved, but the device complexity increases
Solution Approach 1:
The stopper parts are merged with the existing cover and base structures rather than being separate additional components. The first stopper part is formed as an integral part of the cover, and the second stopper part is formed as an integral part of the base, combining the restraint function with the structural components to minimize overall complexity.
Solution Approach 2:
The stopper parts serve multiple functions: they provide restraint against cover edge movement, maintain the appearance of the assembly, and are formed as integral parts of the cover and base during manufacturing. This multi-functionality reduces the need for separate components and simplifies the overall assembly structure.
3Productivity
If the cover edge is allowed to move freely, then the assembly process is fast, but the appearance is spoiled and mechanical issues may occur
Solution Approach 1:
The stopper parts are preliminarily formed as integral parts of the cover and base during their respective manufacturing processes, before assembly. This preliminary formation ensures that the restraint mechanism is already in place and requires no additional assembly steps, maintaining fast assembly speed while preventing appearance degradation.
