Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic systems face complexity in managing and controlling multiple driving units within a single device, requiring cumbersome ID assignment and management, especially when transitioning between devices with single and multiple driving units, leading to increased software complexity and maintenance challenges.
Innovation Solution
A module and method for linking driving units in a robot system that uses a communication unit, control unit, and device information unit to manage and control multiple driving units individually through unique identifiers, allowing direct access to control tables without requiring special conversion processes, enabling efficient management and control of multiple driving units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving units are added to one device, then the functionality and capability of the device are improved, but the complexity of managing and controlling the driving units increases
Solution Approach 1:
The patent segments the identification and management system by introducing a two-level ID structure: device ID for the overall device and driving unit ID for individual driving units. This segmentation allows each driving unit to be independently identified and managed within the device, resolving the complexity issue while maintaining the ability to handle multiple driving units.
Solution Approach 2:
The patent adds another dimension to the identification system by incorporating driving unit ID as a secondary level beneath the device ID. This dimensional expansion transforms the flat single-ID system into a hierarchical two-level system, enabling precise identification of individual driving units within a device without increasing overall system complexity.
2Measurement precision
If separate ID assignment methods are used for devices with single and multiple driving units, then precise control of driving units is achieved, but the software implementation complexity increases
Solution Approach 1:
The patent creates a universal identification system using the device ID - driving unit ID structure that works for both devices with single driving units and devices with multiple driving units. This universal approach eliminates the need for separate ID assignment methods, allowing the same system to handle different device configurations uniformly, thereby reducing software implementation complexity.
3Ease of operation
If device ID is used to access driving unit information, then simple access method is maintained, but the ability to individually manage multiple driving units is lost
Solution Approach 1:
The patent segments the identification process into two clear steps: first accessing the device using device ID, then accessing the specific driving unit using driving unit ID. This segmentation maintains the simplicity of device-level access while enabling precise driving unit-level information retrieval, preventing loss of specific driving unit information.
Solution Approach 2:
The patent adds another dimension to the access hierarchy by introducing driving unit ID as a secondary identification level. This dimensional addition allows the system to maintain simple device-level access through device ID while simultaneously enabling precise driving unit information retrieval through the extended driving unit ID, thus preserving both accessibility and information integrity.
