Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the motor and control unit are arranged in a direction along the rotational shaft, then the spatial arrangement is achieved, but mounting errors accumulate and position accuracy deteriorates
Solution Approach 1:
The patent merges the control unit mounting flange and relay terminal into a single integrally formed connection part. This integration eliminates the need for separate mounting and electrical connection operations, thereby preventing the accumulation of mounting errors and maintaining position accuracy while achieving the required spatial arrangement along the rotational shaft direction.
Solution Approach 2:
The connection part serves multiple functions simultaneously: it provides mechanical mounting for the control unit through the ring-shaped flange and establishes electrical connections through the integrated relay terminal. This multi-functionality reduces the number of separate components and operations, preventing error accumulation while achieving precise spatial arrangement.
2Strength
If separate mounting surfaces are used for motor and control unit, then mechanical connection is achieved, but electrical connection precision deteriorates due to accumulated mounting errors
Solution Approach 1:
The patent combines the mechanical mounting function (control unit mounting flange) and electrical connection function (relay terminal) into a single integrally formed connection part. This ensures that both mechanical and electrical connections are established simultaneously with a single positioning reference, preventing the accumulation of mounting errors that would otherwise affect electrical connection precision.
3Adaptability or versatility
If multiple separate components are used for connection, then flexibility is achieved, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent integrates multiple separate components (control unit mounting flange and relay terminal) into a single connection part. This reduction in the number of parts simplifies assembly while the integral design maintains the necessary flexibility for both mechanical mounting and electrical connection functions.
Solution Approach 2:
The single connection part performs multiple functions: mechanical mounting of the control unit and electrical connection via the relay terminal. This multi-functionality eliminates the need for separate components while maintaining the flexibility required for both mounting and electrical connection operations.
