Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate components are used for driving assembly, speed reduction assembly, braking assembly, and encoding assembly, then each component can be independently manufactured and maintained, but the overall structure becomes complex and costs increase
Solution Approach 1:
The patent combines the driving assembly, speed reduction assembly, braking assembly, and encoding assembly into a single integrated joint module with a unified housing. This merging reduces the number of separate components, simplifies the overall structure, and lowers assembly complexity while maintaining the functional independence of each sub-assembly through modular internal design.
2Reliability
If multiple separate assemblies are used in the robot arm joint, then functional requirements can be met, but the dead weight increases and overall precision decreases
Solution Approach 1:
By integrating multiple assemblies into a single joint module with shared housing and common mounting structures, the patent reduces redundant materials and connection elements. This merging decreases the overall dead weight of the joint module while maintaining all required functions through carefully designed internal arrangements of the driving, speed reduction, braking, and encoding assemblies.
3Ease of repair
If separate components are used for each assembly, then maintenance and replacement can be done individually, but the assembly and integration process becomes time-consuming
Solution Approach 1:
The patent employs modular design within the integrated joint module, where each assembly (driving, speed reduction, braking, encoding) is designed as a distinct functional unit with standardized interfaces. This segmentation allows individual assemblies to be independently manufactured, tested, and replaced when needed, while the unified housing and standardization reduce the overall assembly time during integration.
4Ease of manufacture
If traditional separate component design is used, then each component can be optimized independently, but the overall cost efficiency decreases
Solution Approach 1:
The patent merges multiple assemblies into an integrated joint module that shares common housing, mounting structures, and alignment references. This integration reduces the number of separate manufacturing processes, simplifies quality control, and lowers overall production costs while maintaining the ability to independently optimize each functional assembly through modular internal design and standardized interfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated joint module simplifies the structure of the robot arm, reduces costs, and enhances its ability to handle heavy loads while maintaining precision and reliability.
Implementation Method 1
an area of a cross section of the pair of contact surfaces perpendicular to the axial direction of the output shaft gradually increases or decreases along the axial direction of the output shaft. The base is configured to provide a pressing force to the pair of contact surfaces along the axial direction of the output shaft after being fixed, to allow the rotating shaft to rotate with the output shaft under an action of a friction between the pair of contact surfaces.
