Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workers use glasses-type wearable terminals for hands-free operation, then ease of operation is improved, but reliability deteriorates because workers may forget or imperfectly execute steps due to noise or distractions
Solution Approach 1:
The system incorporates feedback mechanisms where sensors detect the completion of work steps and automatically trigger the display of next instructions. This closed-loop feedback ensures workers don't forget steps while maintaining hands-free operation, as the system actively confirms task completion and guides the next action without requiring worker memory or attention.
Solution Approach 2:
The system performs preliminary actions by pre-displaying multiple work instructions in advance and using sensors to detect when previous steps are completed before showing the next instructions. This ensures workers are always prepared for the next step without needing to remember or anticipate actions, improving both ease of operation and reliability.
2Reliability
If workers manually check work completion and next steps, then reliability is improved, but productivity deteriorates due to time lost moving between positions and checking displays
Solution Approach 1:
The system provides self-service functionality where sensors automatically detect work completion and trigger the display of next instructions without requiring workers to manually check or move between positions. The system serves itself by monitoring task completion status and autonomously advancing the instruction sequence, eliminating productivity losses while maintaining reliable work verification.
Solution Approach 2:
The system ensures continuity of useful action by continuously displaying work instructions and automatically advancing to the next step as soon as the current step is detected as complete. This eliminates interruptions and movements between positions, maintaining continuous productive work while ensuring reliable completion verification through sensor feedback.
3Ease of operation
If the system displays all work instructions at once, then ease of operation is improved, but reliability deteriorates because workers may miss important details or forget steps
Solution Approach 1:
The system segments work instructions into discrete, sequential steps that are displayed one at a time or in small groups. Sensors detect completion of each segment and automatically trigger the next segment. This segmentation prevents workers from being overwhelmed by all instructions at once while ensuring reliable execution through focused attention on current steps and automatic progression.
Solution Approach 2:
The instruction display is dynamic rather than static, automatically adapting to sensor-detected work completion. The system transitions from displaying current instructions to displaying next instructions based on real-time sensor feedback. This dynamic behavior ensures workers see only relevant current steps (improving ease of operation) while automatically ensuring all steps are executed (improving reliability).

AI summary
According to one embodiment, a display and a sensor signal acceptor which accepts detection signals from a sensor are provided. A first display controller displays a first instruction for instructing a first work on the display, based on the detection signal which indicates an end of preparation for the first work. And, a second display controller displays a second instruction for instructing a next second work on the display, based on the detection signal which indicates an end of the first work.
