Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional encoders use multiple components connected through fixing clips and elements, then the encoder can be assembled, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent merges the bracket and bearing attaching portion into a single integrated component processed as one workpiece. This eliminates the need for separate fixing clips and elements, reducing the total number of components and simplifying the assembly process while maintaining structural integrity and alignment precision.
2Manufacturing precision
If multiple components are used in conventional encoders, then the encoder can be assembled, but assembly position accuracy deteriorates due to component deviations
Solution Approach 1:
The bracket and bearing attaching portion are merged into a single component processed as one workpiece, eliminating cumulative deviations that occur when multiple separate components are assembled together. This ensures identical rotation center axes and precise alignment between the optical coded disc and optical sensing assembly.
3Ease of manufacture
If conventional encoders use multiple fixing elements, then components can be connected, but the assembly process becomes complicated
Solution Approach 1:
The patent combines the bracket and bearing attaching portion into one integrated component, eliminating the need for multiple fixing clips and elements. This simplifies the manufacturing process and reduces assembly time while ensuring precise alignment through single-workpiece processing.
