Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual maintenance work is performed by workers, then flexibility and adaptability in handling various maintenance tasks are improved, but consistency and reliability of work quality deteriorate
Solution Approach 1:
The robot performs maintenance work autonomously without continuous human intervention. The control unit automatically controls the robot to execute maintenance operations based on predetermined conditions, enabling the system to serve itself and eliminate variability introduced by manual operations.
Solution Approach 2:
The system changes the operational parameters from manual control to automated robotic control. By transforming the maintenance execution from human-operated to robot-operated, the system maintains adaptability through programmable instructions while ensuring consistent quality through standardized automated processes.
2Reliability
If a robot is introduced to support maintenance work, then consistency in work quality is improved, but device complexity increases
Solution Approach 1:
The robot is designed with multi-functionality to perform various maintenance tasks including cleaning, inspection, and repair operations. By consolidating multiple maintenance functions into a single robotic system, the patent reduces overall system complexity compared to having separate specialized equipment for each task while maintaining consistent quality across different maintenance operations.
Solution Approach 2:
The measurement unit continuously monitors maintenance work quality and provides feedback to the control unit. When the measurement result indicates unsatisfactory quality, the control unit automatically executes additional operations to correct the issue, creating a closed-loop control system that ensures quality consistency without requiring complex manual intervention protocols.
3Reliability
If additional operations are performed to ensure work quality, then reliability of maintenance outcome is improved, but productivity decreases
Solution Approach 1:
The measurement unit provides real-time feedback on maintenance work quality, enabling the control unit to make immediate decisions about whether additional operations are needed. This feedback mechanism ensures that additional operations are performed only when necessary to meet quality standards, avoiding unnecessary rework that would reduce productivity while maintaining reliable quality outcomes.
Solution Approach 2:
The patent replaces manual mechanical operations with automated robotic operations. The robot can perform additional maintenance operations more quickly and consistently than manual workers, so even when multiple operations are required to achieve quality standards, the overall productivity is maintained or improved due to the faster execution capability of the robotic system.

AI summary
To ensure consistency in quality of maintenance work, a maintenance work support system including a work robot for performing maintenance work for each work item includes: a measurement unit configured to measure a measurement-target part specified for a target work item every time maintenance work for the work item is performed; a determination unit configured to determine whether or not a measurement result measured by the measurement unit satisfies a work quality set for the work item; and a control unit configured to, when it is determined that the work quality is not satisfied, control an additional operation for the maintenance work for the work item to be performed until the determination unit determines that the work quality is satisfied.
