Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional winches, including single and dual motor types, are limited by the output torque and pulling force, restricting their ability to handle larger loads and operate in risky environments.
Innovation Solution
A winch design that allows for the external connection of a third motor, increasing dynamic power by transmitting power from three motors to a driving device, which enhances the pulling force and rate through a gear system, expanding the winch's application scope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor is used in the winch, then the structure is simple, but the output torque and pulling force are limited
Solution Approach 1:
The patent combines multiple motors (single motor, dual motors, or three motors) into one winch system to increase output torque and pulling force. The merging of multiple power sources allows the winch to handle larger loads while maintaining a relatively simple overall structure through modular motor configurations.
2Force
If dual motors are combined to increase torque, then the pulling force increases, but the device complexity increases
Solution Approach 1:
The patent employs a dynamic motor configuration where the number of active motors can be adjusted based on load requirements. The system can operate with one, two, or three motors depending on the pulling force needed, allowing the device complexity to scale dynamically with the operational demands rather than being fixed at maximum complexity.
Solution Approach 2:
The winch system is segmented into modular motor units that can be independently configured. This segmentation allows the system to activate only the necessary number of motors for each task, reducing unnecessary complexity while maintaining the capability for high pulling force when needed.
3Productivity
If more motors are added to increase dynamic power, then the pulling rate increases, but the energy consumption increases
Solution Approach 1:
The patent applies partial action by activating only the necessary number of motors based on the required pulling rate and load conditions. Instead of always running all three motors at full capacity, the system uses one or two motors for lighter loads and activates the third motor only when maximum pulling rate and power are required, thus optimizing energy consumption while maintaining high productivity capability.

Function Achieved in This Case
The winch with an externally connected third motor provides greater pulling force and faster pulling rates, enabling it to handle larger loads and operate in more demanding environments, while allowing for selective disassembly to conserve power and resources when needed.
Implementation Method 1
driving a driving device 12 disposed at another side to affect. The inside of the driving device 12 would drive a rope wheel 13 for rotating after experiencing the driving and deceleration effect of several planetary gear sets
Data Source
AI summary
A winch capable of externally connecting motor is to selectively assemble and increase an externally connected motor (a third motor) on a winch driven by a set of motors so that a driving device disposed inside a driving device box of the winch is driven by dynamic power supplied from three motor at the same time to provide greater pulling force and faster pulling rate for a rope wheel of the winch, thereby providing wider scope of application. Moreover, the externally connected motor (the third motor) can be disassembled when there is no need such that dynamic power is provided by two motors so as to save power and energy resource.
