Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot arm is used to automatically unlock the storage, then the unlocking function is achieved, but the device becomes large and complex
Solution Approach 1:
The patent extracts the essential function of automatic unlocking from the complex robot arm system and implements it using a simplified key-based mechanism. The key unit with rotation driving unit and key movement mechanism contains only the necessary components to perform unlocking, eliminating unnecessary robot arm structures while maintaining automatic operation capability.
Solution Approach 2:
The patent replaces the complex robotic mechanical system with a simpler key-based mechanical system. Instead of using a robot arm with sensors and control systems, the invention uses a key that rotates and moves to engage with the lock, achieving automatic unlocking through a more straightforward mechanical interaction.
2Extent of automation
If a robot arm is used to automatically unlock the storage, then the unlocking function is achieved, but the device size increases
Solution Approach 1:
The patent extracts the essential function of automatic unlocking from the complex robot arm system and implements it using a simplified key-based mechanism. The key unit with rotation driving unit and key movement mechanism contains only the necessary components to perform unlocking, eliminating unnecessary robot arm structures while maintaining automatic operation capability.
3Ease of operation
If a key movement mechanism with elastic biasing member is used, then the key can be moved between spaced and locking/unlocking positions, but the mechanism becomes more complex
Solution Approach 1:
The elastic biasing member automatically returns the key unit to its initial spaced position after unlocking, without requiring additional actuators or control systems. The spring-based mechanism self-regulates the key's position, providing automatic reset functionality that simplifies the overall system while ensuring reliable operation.

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 solution allows for a compact and simplified mechanism to automatically lock and unlock storage containers, reducing the size and complexity of the system.
Implementation Method 1
a first elastic biasing member that is interposed between the key unit and the driving force applying member and that normally moves the key unit back and forth integrally with the driving force applying member while moving the key unit back and forth relative to the driving force applying member when the key unit is subjected to an external force opposite to a direction of back/forth movement of the driving force applying member
