Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robot arms require a more integrated and cost-effective joint module design to handle heavy loads and complex operations, with existing designs often having separate components that complicate assembly and increase costs.
Innovation Solution
The integrated joint module incorporates a housing, driving assembly, speed reduction assembly, braking assembly, and encoding assembly, where the housing serves as a shell structure for the driving assembly, and the speed reduction and braking assemblies are connected to the output shaft, with the encoding assembly arranged on the braking assembly, simplifying the structure and reducing costs by allowing direct mounting of components.
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 housing of the driving assembly to also serve as the housing for the speed reduction assembly, braking assembly, and encoding assembly. This merging of housing structures reduces the total number of components and simplifies the overall structure while maintaining independent functionality of each assembly, directly addressing the contradiction between independent manufacturability and structural complexity
2Ease of operation
If separate housings are used for each assembly, then each assembly can be independently assembled and tested, but the total number of parts increases and costs rise
Solution Approach 1:
The patent merges multiple separate housings into a single integrated housing structure that accommodates the driving assembly, speed reduction assembly, braking assembly, and encoding assembly. This reduces the quantity of parts while preserving independent assembly capabilities through modular internal configurations
Solution Approach 2:
The integrated housing serves multiple functions simultaneously: it provides structural support for the driving assembly, contains the speed reduction mechanism, supports the braking assembly, and protects the encoding assembly. This multi-functionality reduces the total part count while maintaining operational independence of each subsystem
3Reliability
If traditional separate component design is used, then reliability of individual components can be optimized independently, but assembly complexity and manufacturing costs increase
Solution Approach 1:
The patent combines multiple assembly housings into one integrated structure that maintains distinct functional zones for each assembly (driving, speed reduction, braking, encoding). This allows each component to be optimized for reliability independently while reducing overall assembly complexity through the unified housing structure

Function Achieved in This Case
This design simplifies the joint module's structure, reduces costs, and enhances the robot arm's ability to handle heavy loads and complex operations by providing a more integrated and efficient assembly process.
Implementation Method 1
an area of a cross section of the pair of the 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
