Detachable Hinge Structure With Integrated Shaft and Angle Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hinge structures require multiple independent components, leading to high manufacturing costs and complex assembly processes due to the need for a separate shaft and metal plates, which complicates the manufacturing and installation of the hinge mechanism.
Innovation Solution
A hinge structure where the shaft is integrally formed with one component and received within a bushing, allowing for rotational freedom and simplified assembly by using a connection member and limiting member to control the detachable and non-detachable states, reducing the overall element count and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge is formed with a shaft and two metal plates with bushings as separate components, then the hinge provides stable rotation function, but the manufacturing cost increases and assembly time increases
Solution Approach 1:
The patent combines the shaft and one metal plate into a single integrated component, reducing the total number of parts from three (shaft, two metal plates) to two (integrated component, one metal plate). This merging maintains the rotational function while simplifying the overall structure and reducing assembly complexity.
Solution Approach 2:
The integrated component serves multiple functions simultaneously: it provides the rotational shaft function, acts as one of the mounting plates, and includes the limiting member for positioning. This multi-functionality reduces the need for separate components while maintaining structural integrity and operational reliability.
2Ease of manufacture
If the shaft and two metal plates are manufactured independently, then each component can be produced separately, but the manufacturing cost increases and assembly process becomes complex
Solution Approach 1:
By integrating the shaft and one metal plate into a single component, the patent reduces the number of assembly operations required. Instead of assembling three separate components (shaft, plate1, plate2), the system now requires assembling only two components (integrated component, plate2), thereby improving assembly speed and productivity.
Solution Approach 2:
The shaft and metal plate are pre-integrated into a single component during manufacturing, performing the assembly action in advance. This preliminary integration eliminates the need for separate assembly steps during final product assembly, thereby improving overall manufacturing efficiency and productivity.
3Reliability
If the shaft is mounted between two bushings, then the rotation is supported, but the assembly and disassembly time increases
Solution Approach 1:
The patent extracts one bushing from the system by integrating its function directly into the metal plate structure. Instead of having separate bushings that need to be assembled around the shaft, the plate itself provides the bearing surface and positioning, eliminating the need for separate bushing components and reducing assembly time.
Solution Approach 2:
The bushing function is merged with the metal plate by incorporating the bearing surface and positioning features directly into the plate structure. This integration eliminates the need for separate bushing components, thereby reducing the number of assembly steps and decreasing overall assembly time while maintaining rotational support functionality.

AI summary
A hinge structure and a casing using the same are provided. The hinge structure includes a first component and a second component. The first component includes a shaft and a connection member, wherein the shaft is fixed on the connection member. The second component includes a bushing and a limiting member, wherein the shaft is received in the bushing, the limiting member is disposed on the bushing, and the first component is detachably installed on the second component through the limiting member.
