Hinge Assembly With Axial Pressure Adjustment for Stable Fan Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge assemblies in household appliances are cumbersome to install due to the need for precise alignment of connection walls in a groove, and fans suffer from poor stability due to the semi-circular arc-shaped fulcrum used for rotation.
Innovation Solution
A hinge assembly comprising a rotation shaft with a first and second connection member arranged sequentially, allowing for easier assembly and increased rotation angle, along with an adjustment member to adjust axial pressure, enhancing reliability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connection walls are installed in an installation groove of the fixation seat in advance, then the hinge assembly can be assembled, but the assembly process becomes cumbersome and inconvenient
Solution Approach 1:
The hinge assembly is divided into separate modular components: a fixation seat and a connection assembly. The connection assembly includes connection walls that can be independently assembled and then attached to the fixation seat, eliminating the need for precise pre-installation in grooves. This segmentation allows for easier manufacturing and assembly while reducing process complexity.
2Ease of operation
If a semi-circular arc-shaped fulcrum is used for fan head rotation, then the fan head can rotate, but the stability of the fan head becomes poor
Solution Approach 1:
The fulcrum structure is designed with dynamic adjustment capabilities. The connection assembly includes adjustable connection walls that can be positioned and fixed at different locations, allowing the fulcrum to adapt to different operational requirements. This dynamic design enables the fan head to rotate smoothly while maintaining stability through adjustable support points.
3Productivity
If the second connection member is positioned at one side of the first connection member along the axial direction, then the assembly efficiency is improved, but the rotation angle needs to be increased to satisfy different usage scenarios
Solution Approach 1:
The connection members are arranged in both axial and radial dimensions. The second connection member is positioned at one side of the first connection member along the axial direction, while also allowing radial adjustment. This multi-dimensional arrangement enables sequential mounting for improved assembly efficiency while providing sufficient rotation angle through radial positioning adjustments to satisfy different usage scenarios.
