Fixing Member Projection Structure for Easier Visual Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing C-shaped fixing members with short boss members make it difficult for operators to visually align and assemble the fixing member with the target member, reducing workability due to the need to change viewing angles during assembly.
Innovation Solution
A fixing member design featuring two holding portions, a joining portion, and a projecting portion that protrudes from the joining portion, allowing easy visibility and assembly, with the projecting portion having a length to penetrate the target member and engagement projections to prevent dislodgment, and optionally including elastic pieces for size variation accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the boss member is made short to simplify the structure, then the structure is simpler, but the operator cannot easily see the positioning portion during assembly
Solution Approach 1:
The projecting portion extends in the axial direction of the pipe, creating a new dimensional arrangement where the positioning feature protrudes beyond the plane of the holding portions. This allows the operator to view and align the boss member from the front without needing to change viewing angles, resolving the contradiction between simple structure and easy assembly.
2Reliability
If the projecting portion is made long to penetrate the target member, then the assembly stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The projecting portion is divided into distinct functional segments: a cylindrical body portion for penetration and positioning, and a tapered leading end portion for easy insertion. This segmentation allows each part to perform its specific function optimally while keeping the overall structure relatively simple and manufacturable.
Solution Approach 2:
Different portions of the projecting portion have different geometric properties tailored to their specific functions. The body portion has a uniform cylindrical shape for stable penetration, while the leading end has a tapered shape for easy insertion. This local differentiation of geometry optimizes performance without requiring complex overall结构设计.
3Strength
If the first maximum diameter of the projecting portion is made larger to increase strength, then the strength is improved, but the ease of insertion into the hole is reduced
Solution Approach 1:
The projecting portion has different diameters at different locations: a larger first maximum diameter at the body portion for strength, and a smaller second maximum diameter at the leading end for easy insertion. This local variation in geometry allows the component to simultaneously satisfy both strength requirements and insertion ease requirements.
Solution Approach 2:
Instead of making the entire projecting portion uniformly thick for strength, the design inverts the approach by making the leading end thinner than the body portion. This counterintuitive design allows easy insertion at the insertion point while maintaining overall structural strength through the thicker body.

AI summary
Provided is a fixing member which is used for fixing a component to a target member. The fixing member includes two holding portions, a joining portion, and a projecting portion. The two holding portions are configured to hold the target member from both sides. The joining portion connects two first ends of the two holding portions. The projecting portion protrudes from the joining portion toward an opening between two second ends of the two holding portions. The two second ends are opposite the two first ends of the two holding portions. The projecting portion has an end close to the opening, and the end protrudes further than at least one of the two second ends of the two holding portions in a direction where the projecting portion protrudes from the joining portion.
