Movable-Plate Robot Assembly for Compact Fastener Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly robot systems are large in size, which limits the reachable area of the robot arm, and miniaturization is demanded without compromising this area.
Innovation Solution
A robot system comprising a transport vehicle, a movable plate, a robot, and a fastener supplier, where the robot is located on the movable plate and the fastener supplier is integrated on the plate, allowing the robot to extend its reach without increasing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the robot system is miniaturized, then the size of the robot system is reduced, but the reachable area of the robot arm distal end is narrowed
Solution Approach 1:
The movable plate enables the robot to reach areas outside the transport vehicle by moving in the horizontal direction, effectively extending the reachable area without increasing the robot's physical size. This dimensional movement resolves the contradiction between miniaturization and reachable area.
Solution Approach 2:
The movable plate is configured to move in a predetermined direction, transforming the static robot system into a dynamic one. This allows the robot arm distal end to reach a broader area by combining the robot's arm extension with the plate's translational movement, maintaining large reachable area while keeping compact size.
2Volume of moving object
If components are integrated on the movable plate, then the robot system can be miniaturized, but the device complexity increases
Solution Approach 1:
The fastener supplier is integrated on the movable plate together with the robot, combining multiple functions into a single mobile unit. This merging reduces the overall system size while the modular integration keeps complexity manageable.
Solution Approach 2:
The movable plate serves multiple functions: it supports the robot, enables horizontal movement to extend reachable area, and carries the fastener supplier. This multi-functionality reduces the need for separate components, miniaturizing the system while organizing complexity through unified design.

AI summary
A robot system includes: a transport vehicle; a movable plate that is located on the transport vehicle and moves in a predetermined direction; a robot that is located on the movable plate, includes an arm, and fastens a fastener, and a first fastener supplier that is located on the movable plate and supplies the fastener to a distal end of the arm.
