Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional drilling robots use large excavation devices with multiple drill bits for various scenarios, then drilling capability and versatility are improved, but device size, energy consumption, and cost increase
Solution Approach 1:
The patent applies multi-functionality by integrating both movement and drilling functions into a single screw propeller structure. The four screw propeller barrels can simultaneously function as propulsion mechanisms for moving across terrain and as drilling tools for geological exploration, eliminating the need for separate drill bits and reducing overall device size while maintaining versatility
Solution Approach 2:
The patent merges the movement function and drilling function into a unified screw propeller mechanism. The rotating screw propellers generate thrust for movement while also capable of penetrating and drilling into terrain, combining two previously separate functions into one integrated system that reduces device complexity and size
2Adaptability or versatility
If conventional drilling robots are equipped with various types of drill bits for different drilling scenarios, then adaptability to different terrains is improved, but portability and device simplicity deteriorate
Solution Approach 1:
The screw propeller barrels serve as universal tools that can adapt to different terrain types (soil, sand, snow, ice) through their rotating helical structure, eliminating the need for multiple specialized drill bits. The same structure that propels the robot forward also performs drilling functions across various terrains
Solution Approach 2:
The patent employs dynamic adjustment capabilities where the orientation and pitch of the screw propeller barrels can be modified during operation to adapt to different terrain conditions, allowing a single dynamic structure to replace multiple static drill bit configurations
3Speed
If drilling robots use traditional wheel or crawler movement mechanisms, then movement capability is improved, but device size and energy consumption increase
Solution Approach 1:
The patent combines movement and drilling into a single screw propeller mechanism, where the same rotating structure that drills into terrain also generates propulsive force for movement. This eliminates the need for separate wheel or crawler systems, reducing energy consumption and device size while maintaining movement capability
