Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-way clutches and overrunning clutches lack the ability to transmit rotary kinetic energy in both rotational directions, limiting their functionality in applications requiring bidirectional energy transfer.
Innovation Solution
A clutch actuated by initial limit-torque sliding damping, featuring a relay transmission structure assembly with a relay coupling structure and a limit-torque sliding damping device, which enables bidirectional energy transfer by generating a damping effect to drive the passive side of the relay output coupling structure, and a recovering actuation spring to manage the coupling and releasing states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-way clutch or overrunning clutch is used, then the structure is simple and easy to manufacture, but the clutch cannot transmit rotary kinetic energy in both rotational directions
Solution Approach 1:
The clutch device is divided into multiple functional segments: a relay coupling structure with active and passive sides, a limit-torque sliding damping device, and a recovering actuation spring. Each segment performs a specific function, allowing the system to achieve bidirectional energy transfer through coordinated action of these segmented components rather than a single complex mechanism.
Solution Approach 2:
The relay coupling structure acts as an intermediary between the prime mover and the load, enabling bidirectional energy transfer. The active side of the relay coupling structure receives input from the prime mover, while the passive side transmits output to the load, with the limit-torque sliding damping device and recovering actuation spring mediating the torque transmission and control between these sides.
2Adaptability or versatility
If a relay transmission structure assembly with limit-torque sliding damping device is added to enable bidirectional transmission, then the clutch can transmit rotary kinetic energy in both directions, but the device complexity increases
Solution Approach 1:
The relay coupling structure serves multiple functions: it transmits torque bidirectionally, controls engagement and disengagement, and works with the limit-torque sliding damping device to provide both motion transmission and damping. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while achieving bidirectional energy transfer.
Solution Approach 2:
The clutch device employs dynamic elements including the limit-torque sliding damping device that provides variable damping based on operating conditions, and the recovering actuation spring that dynamically adjusts the engagement state. These dynamic characteristics allow the system to adapt to different operational requirements without requiring multiple fixed-configuration mechanisms.
3Ease of operation
If the limit-torque sliding damping device is rotated in the first rotation direction, then the damping effect is generated to drive the passive side of relay output coupling structure, but the conventional clutch cannot link when the passive side is driven in the opposite direction
Solution Approach 1:
The relay coupling structure employs asymmetric design where the active side and passive side have different functional characteristics. The active side is optimized for receiving input from the prime mover in the first rotation direction, while the passive side is designed to transmit output and can be driven in reverse directions. This asymmetric configuration enables bidirectional operation while maintaining optimal performance in the primary transmission direction.
