Front-to-Frame Fastening Structure for Stable High Front Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for connecting fronts to frames, particularly those with high overall heights, face stability issues and are often limited to specific frame types, making them unreliable and difficult to mount securely.
Innovation Solution
A fastening device with at least two vertically arranged fastening units that connect the front and frame at multiple interfaces, featuring operative connection means such as coupling members and adjustable elements, allowing for secure attachment and easy detachment, regardless of frame type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single central hanging element is used to connect the front to the frame, then the device is simple in structure, but stability problems arise when connecting high fronts to the frame
Solution Approach 1:
The fastening device is divided into multiple fastening units (at least two) arranged vertically along the front height. Each fastening unit independently connects the front to the frame at different vertical positions, distributing the mechanical load and significantly improving connection stability for high fronts while maintaining reasonable structural complexity through modular design
2Reliability
If fastening units are arranged at multiple vertical positions, then connection stability is improved, but the number of fastening operations increases
Solution Approach 1:
Multiple fastening units are mechanically coupled through coupling members (such as coupling rods) that connect the fastening elements across different vertical positions. This allows a single fastening operation to simultaneously engage multiple fastening units, achieving stable multi-point connection while minimizing the time and effort required for installation
3Ease of manufacture
If the fastening device is designed for specific frame types, then the fastening mechanism can be optimized, but adaptability to different frame types is reduced
Solution Approach 1:
The fastening device incorporates adjustable fastening units with coupling members that can accommodate various frame geometries and mounting positions. The modular design with standardized interfaces allows the same fastening mechanism to be adapted to different frame types (hollow chamber frames, solid frames, etc.) while maintaining optimized fastening performance through adjustable positioning and universal coupling principles
