Solution Overview
Problem
Conventional scalar-type transfer apparatuses become larger and more complex due to the need for multiple motors to control multiple hands, complicating their operation and control.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple motors are used to drive multiple hands independently, then each hand can be controlled individually, but the apparatus becomes larger and control becomes more complicated
Solution Approach 1:
Multiple hands are driven by a single motor through a mechanical transmission system. The first and second hands are connected to the motor via pulleys and belts, allowing one motor to simultaneously control the rotation of both hands, thereby reducing the total number of motors and simplifying the control structure
Solution Approach 2:
A pulley system acts as an intermediary mechanism between the motor and the hands. The pulleys transmit and distribute the rotational motion from the single motor to multiple hands, enabling individual control of each hand without requiring separate motors for each
2Adaptability or versatility
If multiple motors are used to drive multiple hands, then independent control is achieved, but the apparatus size increases
Solution Approach 1:
The motor function is merged into a single unit that serves multiple hands. By combining the driving function of multiple motors into one motor with a transmission system, the overall apparatus volume is reduced while maintaining the capability for independent hand control
Solution Approach 2:
A single motor is designed to perform multiple functions by driving multiple hands simultaneously. The motor serves as a universal driving source that can control different hands independently through the transmission mechanism, eliminating the need for multiple dedicated motors
3Ease of operation
If multiple motors are used for multiple hands, then precise individual control is possible, but the control system becomes more complicated
Solution Approach 1:
The control complexity is extracted from the motor level and shifted to the transmission mechanism level. By taking out the individual motor control requirement and replacing it with a mechanical transmission system, the control system becomes simpler while maintaining precise individual hand control capability
Solution Approach 2:
The transmission mechanism automatically distributes the motor's rotational output to multiple hands without requiring complex electronic control systems. The mechanical system self-regulates the motion distribution, reducing the burden on the control system
