Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with hinge mechanisms face challenges in providing a stable rotating shaft that can be easily tested and adjusted under various conditions to ensure optimal performance.
Innovation Solution
The electronic device incorporates a hinge mechanism with a fixed member, elastic piece assembly, rotating shaft, and locking assembly, where the locking assembly drives the elastic piece assembly to clamp the rotating shaft with adjustable clamping forces, allowing for flexible adjustment of torque and rotational stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the rotating shaft is tightly clamped to ensure stability, then the rotational stability is improved, but the adjustment and testing flexibility deteriorates
Solution Approach 1:
The hinge mechanism employs a dynamic clamping system where the elastic piece can be positioned at different locations along the rotating shaft through the locking assembly. This allows the clamping force to be dynamically adjusted - tighter for stability during operation, and looser or repositioned for adjustment and testing, resolving the contradiction between rotational stability and adjustment flexibility
Solution Approach 2:
The system changes the parameter of clamping force by allowing the locking assembly to engage the elastic piece at different positions. By varying the position of the elastic piece relative to the rotating shaft, the clamping force parameter can be adjusted to meet different operational requirements, enabling both stable operation and flexible testing
2Reliability
If the entire display module or pivot shaft is replaced during testing or repairs, then the reliability is improved, but the ease of repair and manufacturing cost deteriorates
Solution Approach 1:
The hinge mechanism is segmented into independent components - the rotating shaft, elastic piece, locking assembly, and fixed member. This segmentation allows the rotating shaft to be independently replaced or adjusted without affecting the entire display module, improving ease of repair while maintaining reliability through dedicated replacement of only the faulty component
Solution Approach 2:
The rotating shaft is extracted as a separate, independently replaceable component from the display module assembly. The locking assembly and elastic piece can be adjusted or replaced independently to fix hinge mechanism issues, eliminating the need to replace the entire display module and reducing both repair complexity and manufacturing costs

Function Achieved in This Case
This solution enables quick and convenient adjustment of the clamping force on the rotating shaft, facilitating precise calibration of the hinge mechanism's torque, reducing the need for replacing the entire display module or pivot shaft during testing or repairs, and improving the stability and usability of the device.
Implementation Method 1
the elastic piece assembly moves toward the rotating shaft and clamps the rotating shaft, wherein the elastic piece assembly applies a first clamping force to the rotating shaft

AI summary
An electronic device is provided, including a base, a display module, and a hinge mechanism. The hinge mechanism connects the base and the display module, and includes a fixed member, an elastic piece assembly, a rotating shaft, and a locking assembly. The fixed member is fixed to the base, and the elastic piece assembly is disposed on the fixed member and has a through slot. The rotating shaft is disposed through the fixed member and the elastic piece assembly, and is connected to the display module. The locking assembly is disposed through the elastic piece assembly. When the locking assembly is locked into the through slot in a first direction, the locking assembly drives the elastic piece assembly to move toward and clamps the rotating shaft, wherein the elastic piece assembly applies a first clamping force to the rotating shaft.
