Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems face challenges in maintaining high accuracy and stability when moved to different locations, as they require time-consuming stabilization and fixing processes, which can lead to vibration issues and increased installation time.
Innovation Solution
A robot system with a moving stand that includes adjustable legs with a holding-force changing portion, allowing the system to dynamically adjust the fixing holding-force between the legs and the floor based on the robot's state, thereby stabilizing the system quickly and reducing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot apparatus is moved to different locations, then the robot can work in multiple places and reduce the number of robot apparatuses needed, but the robot cannot perform work with high accuracy if not stabilized in the new location
Solution Approach 1:
The stand incorporates adjustable legs with holding-force changing portions that can dynamically adjust the fixing strength between the stand and floor. This allows the stand to transition from a mobile state (when moving) to a stabilized state (when working), resolving the contradiction between mobility and work accuracy by making the fixation strength adjustable rather than fixed
Solution Approach 2:
The holding-force changing portion modifies the physical parameter of fixing strength between the stand and floor. By changing this parameter, the system can achieve both mobility (when holding force is reduced) and stability (when holding force is increased), thereby resolving the contradiction between adaptability and manufacturing precision
2Manufacturing precision
If the stand is fixed firmly to the floor using traditional methods (clamps, positioning pins), then the robot can work with high accuracy, but the installation time and stabilization process become time-consuming
Solution Approach 1:
The invention replaces traditional mechanical fixing methods (clamps requiring tightening, positioning pins requiring insertion and securing) with a holding-force changing portion that can rapidly adjust fixation strength. This substitution eliminates time-consuming manual operations while maintaining the necessary stability for high-accuracy work
Solution Approach 2:
The stand is pre-equipped with the holding-force changing portion and adjustable legs, allowing for rapid deployment. When the stand is placed on the floor, the holding force can be quickly adjusted to the required level without needing preliminary preparation or complex installation procedures, thereby reducing installation and stabilization time
3Stability of the object's composition
If the stand uses fixed fixing strength to the floor, then the robot can be stabilized, but the system cannot adapt to different working conditions and robot states
Solution Approach 1:
The holding-force changing portion makes the fixation strength dynamic rather than static. It can adjust the holding force between the stand and floor based on the robot's working state, thereby providing both stability when needed and adaptability when working conditions change
Solution Approach 2:
The system changes the physical parameter of holding force between the stand and floor according to different robot states. This parameter change enables the stand to adapt to various working conditions while maintaining sufficient stability, resolving the contradiction between stability and adaptability
