Solution Overview
Problem
Existing assembly jig positioning systems rely on manual adjustments, which are time-consuming and prone to human error, leading to inefficiencies and potential malfunctions in positioning assembly components.
Innovation Solution
A jig positioning system incorporating a robot arm and a control unit that grips and positions assembly jigs on an assembly table, adjusting their position and orientation based on the shapes of the components, enabling automated and precise placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual adjustments are used for positioning assembly jigs, then the system is simple to operate, but the positioning time is excessive and error-prone
Solution Approach 1:
The patent replaces manual mechanical positioning operations with an automated robot arm system controlled by a control unit. The robot arm mechanically positions the assembly jigs on the assembly table based on component shapes, eliminating manual adjustments and significantly reducing positioning time while maintaining system functionality.
Solution Approach 2:
The system enables the assembly jig positioning process to be self-serviced through automated robot arm operations. The control unit autonomously controls the robot arm to grip and position multiple assembly jigs in sequence according to component shapes, without requiring manual intervention for each positioning operation.
2Adaptability or versatility
If multiple assembly jigs are used for different components, then the adaptability is improved, but the device complexity and handling requirements increase
Solution Approach 1:
The robot arm system is designed to handle multiple different assembly jigs for different assembly components, making the positioning system universal. The control unit can selectively grip and position various types of assembly jigs based on the specific component shapes, enabling one system to perform multiple positioning functions without requiring specialized manual handling for each jig type.
Solution Approach 2:
The robot arm acts as an intermediary between the control unit and the assembly jigs. It gripps the assembly jigs including the assembly jig and transfers them to appropriate positions on the assembly table, simplifying the interaction between the control system and multiple different jig types while maintaining adaptability.
3Productivity
If automated robot arm positioning is implemented, then productivity is improved, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical positioning operations with an automated robot arm system controlled by a control unit. The robot arm mechanically positions the assembly jigs on the assembly table based on component shapes, eliminating manual adjustments and significantly reducing positioning time while maintaining system functionality.
Solution Approach 2:
The system enables the assembly jig positioning process to be self-serviced through automated robot arm operations. The control unit autonomously controls the robot arm to grip and position multiple assembly jigs in sequence according to component shapes, without requiring manual intervention for each positioning operation.

AI summary
A jig positioning system includes a robot arm and a control unit. The robot arm grips an assembly jig designed to be positioned on an assembly table. The control unit controls motion of the robot arm. The control unit causes the robot arm: to grip one or more assembly jigs including the assembly jig that are to be selected in sequence for assembly components; and to adjust position and orientation of each of the one or more assembly jigs in accordance with shapes of the assembly components in course of positioning of the assembly jigs on the one or more assembly table.
