Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the triaxial chamber cavity is large in size and heavy in weight to simulate deep temperature and horizontal in-situ stress, then the simulated environment accuracy is improved, but the ease of operation deteriorates as multiple operators are required for lifting and lowering
Solution Approach 1:
The patent replaces the manual mechanical lifting system with an automated hoisting system. The hoisting mechanism automatically lifts and lowers the chamber cavity along the guide rod, eliminating the need for multiple operators to manually handle the heavy chamber. This substitution maintains the large size and weight of the chamber for accurate deep underground environment simulation while resolving the operational difficulty.
2Device complexity
If manual lifting is used to install and disassemble the chamber cavity, then the device complexity is reduced, but the reliability deteriorates due to safety risks and potential damage to test piece and equipment
Solution Approach 1:
The patent introduces a hoisting mechanism as an intermediary device between the operators and the chamber cavity. This intermediary automatically performs the lifting and lowering operations, eliminating direct manual handling of the heavy chamber. The guide rod serves as another intermediary that constrains the movement path, ensuring the chamber is positioned accurately and safely without damaging the test piece or equipment.
Solution Approach 2:
The chamber cavity is equipped with self-service features including the guide rod that automatically guides its movement during lifting and lowering, and the coupling device that automatically connects and disconnects from the test pedestal. These self-service mechanisms reduce the need for complex manual operation procedures while improving safety and reliability.
3Ease of operation
If the chamber cavity is lifted manually with operators applying force by hand to maintain balance, then the ease of operation is improved, but the object-generated harmful factors worsen as operators may be injured due to chamber swinging
Solution Approach 1:
The patent replaces the manual balance-maintaining system with an automated hoisting mechanism. The hoist automatically controls the lifting and lowering motion, eliminating the need for operators to apply force by hand to maintain chamber balance. This substitution removes the safety hazards of chamber swinging and operator injury while maintaining ease of operation through automated control.
Solution Approach 2:
The guide rod acts as a beforehand cushioning mechanism that pre-constrains the movement path of the chamber cavity during lifting and lowering. By providing this predetermined guidance path before any potential swinging or instability occurs, the system prevents harmful oscillations and ensures safe operation without requiring manual balance maintenance.
