Mounting Structure With Deformable Restrictions For Component Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting structures for mounting components require high accuracy in the holding portion to prevent the component from falling, which can be complex and costly to achieve.
Innovation Solution
A mounting structure with a cylindrical portion and radially enlarged portion, featuring a communication portion with restrictions that allow the cylindrical portion to be inserted into a bolt through hole, and lightening portions for easy deformation, eliminating the need for high accuracy in the holding portion and reducing weight by integrating moldable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the holding portion uses a simple structure without lightening portions, then the structure is easier to manufacture, but the mounting component cannot be securely held and may fall
Solution Approach 1:
The lightening portions are strategically positioned only in specific regions of the holding portion where material removal facilitates deformation of the restrictions, rather than uniformly thinning the entire structure. This localized approach enables easy deformation of the restrictions to secure the mounting component while maintaining structural integrity elsewhere, resolving the contradiction between ease of manufacture and holding reliability.
2Reliability
If the holding portion requires high accuracy to prevent falling, then the mounting component is securely held, but the manufacturing cost and complexity increase
Solution Approach 1:
The restrictions are designed as deformable elements that dynamically adapt to the mounting component during insertion. The lightening portions enable the restrictions to elastically deform and grip the component, providing secure holding through dynamic interaction rather than relying on high static manufacturing precision. This transforms the holding mechanism from precision-dependent to deformation-dependent, resolving the contradiction between reliability and manufacturing precision requirements.
3Reliability
If the holding portion structure is complex to prevent falling, then the mounting component is securely held, but the device complexity increases
Solution Approach 1:
The lightening portions are integrated directly into the holding portion as a unified structure, combining the functions of structural support and deformation facilitation in a single component. This merging eliminates the need for separate deformation-facilitating elements or complex assembly mechanisms, achieving secure holding through the integrated lightening portions while maintaining simplicity in the overall device structure, thus resolving the contradiction between reliability and device complexity.

AI summary
A mounting structure for a mounting component is provided with a first member 10 that has a holding portion 40 holding a mounting component 30 and to which a second member is mounted by the mounting component 30, the mounting component 30 having a radially enlarged portion 32 radially enlarged at one end of a cylindrical portion 31. The holding portion 40 has: a housing space 45 for the mounting component 30, which is formed with a side wall portion 42 upstanding from a base portion 11, and a seat portion 44 being continuous with the top of the side wall portion 42 and having a bolt through hole 43 into which a bolt is inserted; and a mounting component insertion hole 46 that is provided in the side wall portion 42 for inserting the mounting component 30 into the housing space 45. The bolt through hole 43 is of such size as to abut on the peripheral surface of the cylindrical portion 31 of the mounting component 30, and provided with: a communication portion 47 that provides communication between the bolt through hole 43 and the mounting component insertion hole 46, for allowing passage of the cylindrical portion 31 of the mounting component 30 into the bolt through hole 43; and restrictions 48 that form a narrow portion in the communication portion 47, the narrow portion being narrower than the outer dimension of the cylindrical portion 31 of the mounting component 30. Thus there is provided a mounting structure for a mounting component, wherein a holding portion need not necessarily have a higher accuracy.
