Clutch Device with Torque-Release Coupling for Induction Bin Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash bins with electric flip mechanisms are prone to overload due to external forces opening or closing the lid, leading to motor damage and reduced service life.
Innovation Solution
A clutch device with a transmission assembly and reset assembly, featuring a first connector with a bump and a second connector with a groove, and an elastic element to stabilize or separate the connectors based on torque input, preventing overload rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor is directly connected to the lid through the transmission assembly, then the lid can be opened and closed automatically, but the motor is prone to overload damage when external forces are applied
Solution Approach 1:
The second connector acts as an intermediary component between the motor and the lid. It includes a groove that can engage with a protrusion on the first connector to transmit torque, but also allows the first connector to rotate independently when excessive torque is applied, thereby protecting the motor from overload damage while maintaining automatic operation capability
Solution Approach 2:
The elastic element changes its compression state based on the torque applied to the system. Under normal operating torque, the elastic element maintains engagement between connectors for torque transmission. When excessive torque is applied, the elastic element compresses, allowing the connectors to disengage and the first connector to rotate independently, thus changing the mechanical coupling parameter to prevent motor damage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents overload damage by allowing no-load rotation when excessive torque is applied, thereby prolonging the service life of the motor and the trash bin.
Implementation Method 1
the reset assembly includes an elastic element, which is configured to drive the second connector to move towards the first connector
