Clip Connection Structure to Prevent Outer-Inner Member Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structure is prone to detachment when an external force is applied, requiring additional engagement efforts to maintain the connection between the clip and the shaft end washer.
Innovation Solution
A connection structure that includes an engaging member with a holding part attached to the outer member, featuring first and second holding elements, extension parts, and a connection element, which are designed to engage with inner-member and outer-member engaging parts, restraining relative movement and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple clip with two insertion parts is used for connection, then the connection structure is easy to form, but the clip is easily detached when external force is applied
Solution Approach 1:
The holding part is divided into multiple holding elements (first holding element with first and second extension parts, second holding element with third extension part) that engage with corresponding engaging parts on both the outer and inner members. This segmentation creates multiple engagement points that distribute the load and prevent detachment while maintaining ease of assembly through the two-insertion-part structure.
2Ease of operation
If the engaging member is designed to be easily inserted, then workability is improved, but the engaging member cannot maintain connection under external force
Solution Approach 1:
The holding elements are designed with elastic properties that allow them to deform during insertion and then maintain continuous contact pressure against the engaging parts. The extension parts can flex to accommodate assembly variations while establishing firm engagement, and this dynamic behavior enables both easy insertion and strong connection maintenance under external forces.

AI summary
A connection structure is provided, wherein relative movement between outer and inner members is restrained by an engaging member. The engaging member includes first and second bolding elements. A connection part connected to another-side end part of the second holding element is provided in one-side end part of the first holding element. A first extension part is provided in another-side end part of the first holding element The connection part includes second and third extension parts, and a connection element extending substantially parallel to the second holding element. The first holding element and the first and second extension parts are provided such that an angle formed by the first holding element and the second extension part, and an angle formed by the first holding element and the first extension part are smaller than 90°. Use of the connection structure, which is easily formable, restrains the engaging member from being detached.
