Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex robot systems, operators face a high burden when manually arranging structural members like robot arms, imaging cameras, and lighting systems due to the numerous combinations of positions and orientations required, leading to inefficiencies in setting up optimal working conditions.
Innovation Solution
An information processing apparatus that generates virtual space images and evaluates the arrangement of structural members based on captured images, using a control unit to set and optimize the positions and orientations of the robot arm, imaging unit, and lighting system, reducing the operator's workload by automating the process through a series of steps and calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the degree of freedom of arrangement of structural members is increased to enable complicated work, then the robot system can perform more complex tasks, but the burden on the operator to visually confirm virtual space images increases significantly
Solution Approach 1:
The system performs self-evaluation by automatically calculating evaluation values for different arrangement combinations using the evaluation expression, eliminating the need for operator visual confirmation of all 40000 combinations. The computer system serves itself by autonomously determining optimal arrangements.
Solution Approach 2:
The patent replaces the manual visual confirmation process with an automated computer-based evaluation system that calculates arrangement suitability using predefined evaluation expressions, substituting human cognitive effort with computational analysis.
2Adaptability or versatility
If the number of structural members and their arrangement options are increased to handle complicated work, then the robot system becomes more versatile, but the time required to confirm all combinations of virtual space images increases dramatically
Solution Approach 1:
The computer system autonomously evaluates all arrangement combinations by calculating evaluation values based on the evaluation expression, performing the time-consuming analysis task without human intervention and dramatically reducing the time required compared to manual visual confirmation.
Solution Approach 2:
The patent substitutes manual visual inspection with automated computational evaluation, using the computer's processing power to rapidly calculate and compare evaluation values across all 40000 combinations, reducing confirmation time from potentially days to minutes or seconds.
3Measurement precision
If manual arrangement confirmation of virtual space images is used to ensure proper positioning, then arrangement accuracy can be verified, but the operator burden and complexity of operation increase
Solution Approach 1:
The patent replaces manual visual verification with automated computational evaluation that calculates arrangement suitability using the evaluation expression, maintaining measurement precision through systematic calculation while eliminating the complexity of manual operation.
