Fixing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object holder assemblies are heavy due to the casting process used in their manufacture, which affects their usability and installation.
Innovation Solution
A fixing device comprising a metal shell body with a through groove and plastic connecting members that reduce weight and simplify installation by using a hollow shell body made from sheet metal and plastic connecting members with specific groove and hook configurations for secure attachment to a wall and object holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the base seat is formed via a casting process, then the structural strength is improved, but the weight of the object holder becomes relatively heavy
Solution Approach 1:
The invention uses a composite structure combining metal shell body with plastic connecting members and fixing members. The metal shell body (first material) provides structural strength, while the plastic components (second material) reduce overall weight. This composite material approach resolves the contradiction between strength and weight by strategically assigning materials to different functional parts.
Solution Approach 2:
The object holder is divided into multiple segments: the metal shell body and separate plastic connecting members. This segmentation allows each part to be optimized independently - the shell body maintains structural integrity while the plastic connecting members minimize weight, thereby resolving the strength-weight contradiction.
2Weight of moving object
If a metal shell body with through groove and plastic connecting members is used, then the weight of the fixing device is reduced, but the manufacturing complexity increases
Solution Approach 1:
The fixing device is segmented into modular components (metal shell body, plastic connecting members, fixing members) that can be manufactured separately using optimized processes for each material, then assembled. This reduces overall manufacturing complexity despite the multi-material design.
Solution Approach 2:
The plastic connecting members serve multiple functions: structural connection, weight reduction, and integration with both the metal shell body and the object holder. This multi-functionality reduces the number of separate components needed, simplifying the overall manufacturing process.
3Ease of operation
If the connecting portion is inserted into the groove portion, then the assembly ease is improved, but the connection strength may be compromised
Solution Approach 1:
The connecting portion is nested within the groove portion, creating an interlocking relationship. The groove has a receiving space that accommodates the connecting portion, providing both easy insertion (assembly ease) and secure retention (connection strength) through the nested configuration.
Solution Approach 2:
The groove portion is designed with specific local characteristics - a receiving space with defined dimensions and features - that locally enhance the connection between the connecting portion and the shell body. This localized design ensures both ease of assembly and adequate connection strength at the critical interface.

AI summary
A fixing device includes a fixing member adapted to be mounted on a wall, a hollow shell body made of metal and being formed with a through groove, and plastic first and second connecting members. The through groove has a first groove portion extending in a first direction, and a second groove portion extending in a second direction that is substantially perpendicular to the first direction. The first connecting member is securely connected to the fixing member, and has a linking portion inserted into the first groove portion. The second connecting member has a connecting portion inserted into the second groove portion and connected to the linking portion, and is adapted for connection with an object holder.
