Hinge Clutch With Adjustable Torque Wedge Adjuster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinged devices with clutch systems face challenges in smoothly transitioning between rotation and locking positions, often resulting in inefficient user control and potential mechanical failures due to inadequate torque management and backlash in the clutch mechanism.
Innovation Solution
A clutch system incorporating a gear assembly with planet gears, a clutch assembly interposed between the gears, and a wedge adjuster mechanism that allows for adjustable torque settings, enabling seamless rotation locking and unlocking, while minimizing backlash through adjustable compression and tooth configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a clutch system is used to lock and unlock the hinge, then the hinge can maintain fixed positions, but the transition between rotation and locking positions is not smooth
Solution Approach 1:
A clutch assembly is introduced as an intermediary mechanism between the display assembly and base assembly. The clutch includes clutch elements that can engage to lock the hinge at specific angles or disengage to allow free rotation, providing smooth transitions between locked and unlocked states without direct mechanical coupling
2Reliability
If a clutch mechanism is used for locking, then the hinge can be secured, but mechanical failures occur due to inadequate torque management and backlash
Solution Approach 1:
The clutch assembly allows adjustment of engagement parameters including torque thresholds and engagement force. By modifying these parameters, the system can adapt to different operating conditions and load requirements, preventing mechanical failure from excessive torque or improper engagement while maintaining reliable locking when needed
Solution Approach 2:
The clutch mechanism transitions from static locking to dynamic control, allowing the hinge to smoothly transition between locked and unlocked states. The clutch elements can engage and disengage under controlled conditions, managing torque dynamically rather than through rigid mechanical constraints that cause backlash and failure
3Ease of manufacture
If torque settings are fixed in the clutch mechanism, then manufacturing is simplified, but user control and torque adjustment are limited
Solution Approach 1:
The clutch assembly incorporates adjustable torque settings that can be modified by users without requiring special tools or complex manufacturing processes. The adjustment mechanism allows the same clutch component to adapt to different torque requirements while maintaining manufacturing simplicity through standardized parts
