Solution Overview
Problem
Conventional work support systems struggle to provide highly accurate support for users working in passages, such as elevator shafts, due to differences between the actual and designed environments, leading to difficulties in maintaining precise work positions and tool handling.
Innovation Solution
A work support device equipped with a measurement unit to assess the in-passage structure and an irradiation control unit to emit light indicating a corrected work position, combined with a support arm for tool handling, allowing for precise positioning and reduced user workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional work support systems are used, then basic work support is provided, but high accuracy positioning is difficult due to differences between actual and designed passage structures
Solution Approach 1:
The system performs preliminary measurement of the actual passage structure using a measurement unit before work begins. The measured actual passage structure data is stored and used to pre-correct work position information, so that when work proceeds, the positioning is already adapted to the actual conditions rather than relying on predetermined designed structure data alone.
Solution Approach 2:
The system establishes a feedback loop where the measurement unit continuously measures the actual passage structure, the correction unit compares measured data with predetermined data to calculate deviations, and the work position information is updated based on these corrections. This closed-loop feedback ensures continuous adaptation to actual passage conditions.
2Ease of operation
If automated robot systems are used in passages, then work can be performed without human intervention, but flexibility to handle unexpected on-site conditions is reduced
Solution Approach 1:
The system enables users to perform work independently with high accuracy by providing them with corrected work position information that automatically adapts to actual passage conditions. The measurement and correction functions serve the user directly, eliminating the need for complex automated robot systems while maintaining adaptability to on-site conditions.
3Productivity
If predetermined designed structure data is used for work positioning, then work can proceed according to plan, but accuracy is compromised when actual passage structure differs from design
Solution Approach 1:
The system performs preliminary measurement of the actual passage structure before work begins and pre-corrects work position information based on the measured data. This allows work to proceed efficiently with accurate positioning from the start, rather than requiring continuous adjustments during work execution.
Solution Approach 2:
The system dynamically changes the work position parameters by correcting predetermined work position information using measured actual passage structure data. The correction unit calculates position deviations and updates work position coordinates, transforming the positioning parameters to match actual conditions while maintaining work efficiency.

AI summary
According to an embodiment, a work support device includes a measurement unit and an irradiation control unit. The measurement unit measures an in-passage structure of a passage inside of which a user can work. The irradiation control unit controls an irradiation unit 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.
