Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parallel robots are limited in their ability to perform the same or substantially the same operation on multiple objects simultaneously, often requiring separate driving and controlling systems for each movable platform, which complicates their structure and functionality, especially when trying to operate on different orientations or planes.
Innovation Solution
A multiple-movable-platform parallel robot construction method that incorporates two or more symmetric movable platforms, each with the same motion pattern, driven by a single set of driving and controlling systems, allowing for symmetrical operations and enhanced versatility, such as walking or profiling tasks after rotation by 180 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple movable platforms are equipped with independent driving and controlling systems, then each platform can operate independently, but the device complexity increases significantly
Solution Approach 1:
The patent merges multiple driving and controlling systems into a single unified system that can control multiple movable platforms simultaneously. The symmetric configuration allows one set of actuators to drive multiple platforms through shared mechanical connections, reducing the total number of independent systems while maintaining the ability to operate multiple objects concurrently.
Solution Approach 2:
The single driving and controlling system is designed with universal capability to control multiple movable platforms. The symmetric structure enables the same actuator system to serve multiple functions by directing power to different platforms as needed, allowing one system to perform the work of multiple independent systems.
2Device complexity
If parallel robots are designed with symmetric movable platforms sharing a single driving system, then the device complexity is reduced, but achieving coordinated motion on different orientations becomes difficult
Solution Approach 1:
While the overall structure maintains symmetry for complexity reduction, the patent incorporates asymmetric elements in the form of reconfigurable end-effectors or tooling attachments on the movable platforms. These asymmetric components can be adjusted or replaced to accommodate different orientations and task requirements, allowing the symmetric base structure to support asymmetric operational needs.
Solution Approach 2:
The patent employs dynamic reconfiguration capabilities where the symmetric movable platforms can change their operational characteristics in real-time. Through dynamic adjustment of platform orientations, actuator configurations, or task assignments, the system adapts to different operational requirements while maintaining the underlying symmetric structure that reduces complexity.
3Ease of operation
If walking parallel robots use two independent parallel mechanisms, then walking action can be achieved, but the robot cannot operate on opposite planes after 180 degree rotation
Solution Approach 1:
The patent merges two independent parallel mechanisms into a single integrated symmetric structure. The walking legs or support mechanisms are configured symmetrically so that the same mechanical system can support walking in multiple orientations. This unified structure eliminates the limitation of independent mechanisms that cannot operate on opposite planes.
Solution Approach 2:
The symmetric parallel mechanism is designed with universal walking capability across different orientations. The same set of actuators and structural elements can produce walking motion whether the robot is oriented in its original position or rotated 180 degrees, providing multi-functional operation on different planes without requiring separate independent mechanisms.
