Guide Jig Engagement Structure for Precise Insertion Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide jigs do not effectively engage with engagement partners, lacking a mechanism to securely position and fix the jig with respect to the partner, which is necessary for precise alignment and operation in applications like greasing devices for clutch release mechanisms.
Innovation Solution
A guide jig with an engagement portion featuring multiple projecting portions aligned in the direction of insertion, where gaps between these portions are set to match the thickness of the engagement partner, allowing for secure positioning and fixation, and optionally including notched or inclined surfaces for enhanced engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a guide jig is used to guide insertion direction, then insertion alignment is improved, but the jig cannot be securely fixed to the engagement partner
Solution Approach 1:
The engagement portion is divided into multiple projecting portions (at least two) that are disposed in line in the insertion direction. These segmented projecting portions create multiple engagement points with the engagement partner, providing both alignment guidance and secure fixation through distributed contact points.
Solution Approach 2:
The engagement portion acts as an intermediary mechanism between the guide jig body and the engagement partner. It mediates the connection by providing projecting portions that engage with corresponding features on the engagement partner, enabling both positioning and fixation functions.
2Reliability
If the guide jig includes an engagement portion with projecting portions, then fixation capability is improved, but the structure becomes more complex
Solution Approach 1:
The engagement portion is merged with the guide jig body as an integrated structure. The projecting portions are formed as part of the guide jig body itself, combining the fixation function with the existing jig structure without requiring separate fixation components or mechanisms.
Solution Approach 2:
The engagement portion serves multiple functions simultaneously: it provides fixation stability through the projecting portions engaging with the partner, maintains positioning accuracy by preserving the guide function, and simplifies the overall structure by integrating these functions into a single component design.

AI summary
There is provided a guide jig including a guide jig body and an engagement portion provided on the guide jig body and configured to be engaged with an engagement partner with the guide jig body positioned with respect to the engagement partner. The guide jig body includes a guide through hole provided as a through hole extending toward a relevant portion with the engagement portion engaged with the engagement partner and configured to guide the direction of insertion of an insertion portion to be inserted into the through hole and moved toward the relevant portion. The engagement portion includes at least two projecting portions. The at least two projecting portions are disposed in line in the direction of insertion. A gap between adjacent projecting portions, among the at least two projecting portions, is set to have a length corresponding to the thickness of the engagement partner.
