Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors are used to provide driving force to the shuffling mechanism, then the shuffling functionality is enhanced, but power consumption increases
Solution Approach 1:
The patent combines multiple motor functions into a single motor by integrating a brake mechanism and transmission gears. The single motor provides driving force while the brake and gear system enable bidirectional rotation and controlled stopping, eliminating the need for multiple motors and reducing power consumption.
Solution Approach 2:
The single motor is designed to perform multiple functions: driving the shuffling wheel in both directions, controlling start and stop operations, and working in conjunction with the brake mechanism to hold the wheel in position. This multi-functionality replaces what would traditionally require multiple dedicated motors.
2Ease of operation
If multiple motors and complex mechanisms are used, then shuffling control is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple control functions into a unified mechanism. The brake mechanism and transmission gears work together with a single motor to achieve bidirectional rotation and precise control, simplifying the overall system while maintaining operational capability.
Solution Approach 2:
The transmission gear acts as an intermediary between the single motor and the shuffling wheel, enabling the motor to control the wheel's rotation direction and speed. This intermediate mechanism simplifies the direct connection that would otherwise require multiple motors.
3Power
If complex structure with multiple motors is used, then driving capability is enhanced, but reliability decreases due to potential malfunctions
Solution Approach 1:
By combining multiple motor functions into a single motor with integrated brake and transmission systems, the patent reduces the total number of moving parts and potential failure points. The simplified structure with fewer components inherently improves reliability while maintaining sufficient driving capability.
Solution Approach 2:
The brake mechanism automatically holds the shuffling wheel in position when stationary, eliminating the need for continuous motor power or complex control systems to maintain position. This self-holding capability reduces power consumption and eliminates potential malfunction sources related to continuous control.
