Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional drive mechanism with transmission components is used, then the structure is simpler to manufacture, but transmission errors increase and reliability decreases
Solution Approach 1:
The patent removes intermediate transmission components (gears, belts, couplings) from the drive mechanism, directly connecting the motor output shaft to the rotary shaft. This extraction of transmission elements eliminates the sources of transmission error while maintaining a relatively simple overall structure through direct coupling.
Solution Approach 2:
The patent replaces traditional mechanical transmission systems with a direct-drive configuration, where the motor's rotor is directly coupled to the rotary shaft. This substitution eliminates mechanical transmission errors associated with gears and belts, achieving higher reliability through a simplified direct connection.
2Volume of moving object
If components are densely packed to optimize space layout, then volume is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent merges multiple components into integrated assemblies. The motor, encoder, and rotary shaft are combined into a unified direct-drive assembly, reducing the overall volume while managing precision requirements through integrated design rather than dense packing of separate components.
Solution Approach 2:
The patent employs nested arrangements where the encoder is mounted on the motor shaft, and the rotary shaft is positioned within the motor assembly. This nesting approach optimizes space utilization while maintaining manufacturable tolerances through hierarchical integration.
3Reliability
If a direct drive mechanism is used, then transmission error is minimized, but the motor and encoder assembly becomes more complex
Solution Approach 1:
The patent extracts the intermediate transmission elements that would otherwise be needed to achieve accurate rotation, using instead a direct-drive motor-encoder-shaft assembly. This extraction simplifies the overall rotation control while maintaining high accuracy through direct coupling.
4Strength
If aluminum alloy framework is used for fixed and protected components, then durability and water-resistance are enhanced, but manufacturing complexity increases
Solution Approach 1:
The aluminum alloy framework serves multiple functions simultaneously: it provides structural strength and durability, offers IP65 water-resistant protection, and acts as the mounting structure for all internal components. This multi-functionality reduces the need for separate protective housings and mounting brackets, simplifying overall manufacturing.
