Pivoting Lever Device for Direction-Dependent Torque Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting levers in motor vehicles transmit torque in all directions equally due to their one-piece design, making direction-dependent torque transmission unfavorable when only one-directional torque is desired.
Innovation Solution
A pivoting lever device with two swivel arms connected by a joint, where each end face is divided into sections aligned at an obtuse angle, allowing for direction-dependent torque transmission by varying the clearance angle between the sections to control movement transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-piece pivoting lever design is used, then the structure is simple and manufacturing is easy, but direction-dependent torque transmission is not possible
Solution Approach 1:
The pivoting lever is divided into two separate pivoting arms (first pivoting arm and second pivoting arm) connected by a joint. Each arm has end faces divided into sections that can be independently configured. This segmentation enables direction-dependent torque transmission while maintaining manufacturing feasibility through modular assembly.
2Adaptability or versatility
If sections of pivoting arms are aligned at an obtuse angle with clearance, then direction-dependent torque transmission is enabled, but the structure becomes more complex
Solution Approach 1:
The sections of the pivoting arms are configured with asymmetric angular relationships. On one side of the joint, sections are aligned at an obtuse angle with clearance, while on the other side, different angular configurations are possible. This asymmetric design enables direction-dependent torque transmission while maintaining structural simplicity through geometric configuration rather than additional components.
