Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an actuator or complex mechanism is used for detachment of the robot hand, then the detachment function is achieved, but the structure becomes complicated and the number of parts increases
Solution Approach 1:
The patent extracts the detachment function from a complex actuator-based mechanism and implements it through a simple manual operation. The gripping part itself is designed to be movable between a gripping position and a detachment position, allowing the user to simply move the gripping part to detach the robot hand without requiring separate actuators or complex mechanisms.
Solution Approach 2:
The gripping part serves multiple functions: it performs the gripping action on objects and simultaneously serves as the detachment mechanism by being movable between gripping and detachment positions. This multi-functionality eliminates the need for separate actuators dedicated solely to detachment.
2Ease of operation
If a complex mechanism with multiple parts is used, then the detachment function is achieved, but the robot hand becomes expensive
Solution Approach 1:
The patent removes unnecessary actuators and complex mechanisms from the detachment system, retaining only the essential movable gripping part. This reduction in components directly lowers manufacturing costs while preserving the detachment function.
Solution Approach 2:
The design accepts that the gripping part may be a consumable or replaceable component that can be简单地 moved and detached without expensive recovery mechanisms. This approach prioritizes simplicity and low cost over long-term durability of the detachment mechanism.
3Ease of operation
If a complex mechanism with multiple parts is used, then the detachment function is achieved, but the robot hand becomes large in size and heavy in weight
Solution Approach 1:
The patent extracts only the essential element for detachment - the movable gripping part - and eliminates all unnecessary actuators and mechanisms. This minimalistic approach significantly reduces the weight of the robot hand while maintaining the detachment capability.
4Device complexity
If a simplified mechanism is used, then the number of parts is reduced and cost is lowered, but the detachment mechanism must still be reliable
Solution Approach 1:
The gripping part is designed to automatically perform the detachment function through its own movement. When the gripping part is moved to the detachment position, it naturally disengages from the mounting part without requiring additional mechanisms. This self-service approach ensures reliability through simplicity.
Solution Approach 2:
Instead of using a mechanism that actively pushes or pulls to detach, the design inverts the approach by allowing the gripping part's movement to naturally result in detachment. The detachment is achieved through the absence of engagement rather than an active disengagement force.
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
The simplified mechanism reduces the number of parts, makes the robot hand smaller and lighter, and easier to produce, enabling its use in various applications, including home environments, while maintaining effective operation and waterproofing.
Implementation Method 1
a transmission part that includes a magnetic coupling mechanism, and the transmission part may be configured to transmit a driving force of a motor to the gripping part through the magnetic coupling mechanism
