Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The encoder assembly in articulated robots has a complex assembly process due to its multiple components, which complicates the assembly steps.
Innovation Solution
A joint module design that integrates a hollow shaft, speed reducer assembly, motor assembly, and encoder assembly, where the encoder assembly includes an encoder mounting base, outer ring, middle ring, inner ring, input and output code wheels, and encoder read head, allowing for simultaneous assembly of these components by sleeving and connecting them on the hollow shaft and motor assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the encoder assembly includes multiple components assembled in sequence, then the encoder assembly can be completed with all necessary functional elements, but the assembly steps become complicated and time-consuming
Solution Approach 1:
The patent merges multiple encoder components (inner ring, middle ring, outer ring, input code wheel, output code wheel, and encoder read head) into a single integrated encoder assembly that can be assembled simultaneously on the hollow shaft, rather than assembling them separately in sequence. This combining approach reduces assembly steps while maintaining all necessary functional elements.
Solution Approach 2:
The encoder components are pre-configured and positioned on the hollow shaft during the initial assembly process, before final assembly is completed. The inner ring, middle ring, and outer ring are sleeved and connected to the hollow shaft in advance, with the code wheels and read head pre-positioned, enabling simultaneous assembly rather than sequential assembly.
2Manufacturing precision
If multiple encoder components are assembled in sequence, then each component can be properly positioned and connected, but the assembly time and production efficiency are reduced
Solution Approach 1:
The patent combines the assembly of multiple encoder components into a single simultaneous assembly operation. The inner ring, middle ring, outer ring, input code wheel, output code wheel, and encoder read head are all assembled together on the hollow shaft in one process, maintaining positioning accuracy through the integrated structure while significantly improving assembly efficiency.
Solution Approach 2:
The encoder components are nested within each other on the hollow shaft, with the inner ring closest to the hollow shaft, followed by the middle ring, then the outer ring, and the code wheels and read head positioned within this nested structure. This nesting arrangement allows all components to be assembled simultaneously while maintaining precise relative positioning.
3Adaptability or versatility
If the encoder assembly uses multiple separate components, then the design can be flexible and adaptable, but the assembly procedure becomes more complex
Solution Approach 1:
The patent merges the multiple encoder components into an integrated assembly that maintains design flexibility through the modular structure of the inner ring, middle ring, and outer ring configuration, while simplifying the assembly procedure by enabling simultaneous assembly on the hollow shaft rather than requiring complex sequential assembly steps.
