Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional work support methods are used in passages, then basic work functions can be performed, but work precision and accuracy deteriorate due to differences between actual and designed work environments
Solution Approach 1:
The system performs preliminary measurement of the actual passage structure before work begins, and pre-calculates corrected work position information based on the difference between actual and designed structures. This allows the irradiation unit to directly indicate accurate work positions without real-time calculation delays.
Solution Approach 2:
The patent introduces an intermediary processing step that calculates corrected work position information by comparing actual passage structure measurements with designed structure data. This intermediary calculation layer translates raw measurement data into actionable corrected position information that compensates for environmental deviations.
2Manufacturing precision
If manual work support without correction is used, then device complexity is low, but work precision deteriorates due to uncorrected position deviations
Solution Approach 1:
The passage structure measurement unit serves multiple functions: it measures the actual passage structure, calculates position deviations, and provides correction data for work position alignment. This multi-functionality reduces the need for separate correction devices, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system implements a feedback loop where the measurement unit continuously monitors actual passage structure, compares it with designed structure, and adjusts work position information accordingly. This automated feedback mechanism maintains high precision without requiring complex manual intervention systems.
3Measurement precision
If automated correction systems are implemented, then work precision improves, but device complexity increases due to additional measurement and correction components
Solution Approach 1:
The patent merges the measurement function and correction function into an integrated system. The passage structure measurement unit is combined with the work position correction logic, and both are coordinated with the irradiation unit to provide a unified work support solution. This merging reduces the need for separate independent systems.

AI summary
According to an arrangement, a work support device 10 includes a measurement unit 23 and an irradiation control unit 32F. The measurement unit 23 measures an in-passage structure of a passage inside of which a user can work. The irradiation control unit 32F controls an irradiation unit 24 to emit light indicative of a work region to a corrected work position obtained by correcting work position information set based on a predetermined designed in-passage structure indicative of an ideal structure in the passage by using a result of the measurement by the measurement unit 23.
