Decorative Accessory Fixing Structure With Interference-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative accessories face issues of insufficient firmness, complicated installation, limited usage scenarios, and potential damage to items due to the use of elastic buckles and elastic holes for fixation.
Innovation Solution
A fixing structure comprising a connector, mounting shaft, and fixing member with interference fit insertion portions and indentation patterns, made of materials like plastic, zinc alloy, aluminum alloy, and copper, allowing firm fixation without elastic materials, suitable for various usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic buckles and elastic holes are used for fixation, then installation and fixation can be achieved, but the firmness is insufficient and the structure becomes complicated
Solution Approach 1:
The fixation structure is divided into separate components: a connector with first fixing holes, a mounting shaft with insertion portions, and a fixing member with second fixing holes. This segmentation allows each component to perform its specific function independently, achieving firm fixation without requiring complex elastic buckle structures.
Solution Approach 2:
The mounting shaft is inserted through the connector and fixing member, with its insertion portions fitting into the respective fixing holes. This nested arrangement creates a compact, integrated fixation system that eliminates the need for separate elastic buckles and holes, reducing overall structural complexity while maintaining firmness.
2Ease of operation
If elastic holes made of elastic materials are used on items, then installation can be achieved, but the original holes may be damaged and usage scenarios are limited
Solution Approach 1:
The invention extracts the elastic material requirement from the fixation system. Instead of relying on elastic holes in the item (clothes, shoes, bags), the fixation structure uses rigid connector and fixing member components that can be directly attached to the item surface, eliminating the need to create or damage elastic holes in the original item.
Solution Approach 2:
The connector and fixing member act as intermediary components between the decorative accessory and the item. These intermediaries provide the fixation function without requiring direct modification of the item's original holes, thereby avoiding damage while enabling easy installation across various usage scenarios.
3Strength
If elastic buckles and nuts are used for assembly and fixation, then parts can be connected, but the production and machining processes become complicated
Solution Approach 1:
The connector and fixing member are designed as integrated components with built-in fixing holes and insertion portions. This merging of functions into single components eliminates the need for separate elastic buckles and nuts, simplifying both the production process and machining requirements while maintaining strong connection between parts.
Solution Approach 2:
The connector and fixing member serve multiple functions: they provide structural connection, enable decorative accessory attachment, and offer easy installation without requiring specialized elastic materials or complex assembly steps. This multi-functionality reduces production complexity across different application scenarios.
