Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operators visually determine work positions manually, then they can identify work locations, but it requires time and labor leading to low work efficiency
Solution Approach 1:
The work position indicator projects visible light to mark work positions in advance before the operator arrives. This preliminary marking of positions eliminates the need for operators to search and determine work locations manually, directly reducing the time and labor required while maintaining accurate position identification
Solution Approach 2:
The patent replaces the manual visual determination process with an optical system. The work position indicator uses projected visible light to automatically mark positions, substituting the operator's manual visual search with an automated optical indication system, thereby improving efficiency and reducing time loss
2Measurement precision
If the electric tool operates without position verification, then work can proceed quickly, but accuracy of work position may be compromised
Solution Approach 1:
The tool position detector detects the relative position of the electric tool with respect to the marked work position and provides this information to the tool position decider. This feedback loop allows the system to verify position accuracy before work commences, ensuring precision without significantly delaying the workflow since the verification is automated and rapid
Solution Approach 2:
The tool position decider verifies position accuracy in advance before the electric tool carries out work. This preliminary verification ensures that the tool is correctly positioned on the projected light marker before operation begins, guaranteeing work position accuracy while minimizing time loss through automated pre-checking

AI summary
Work efficiency when work is carried out, by using an electric tool, on a work position of a work site is improved. An electric tool system (1) includes a work position indicator (3), an electric tool (2), a tool position detector (36), and a tool position decider (384). The electric tool (2) is configured to carry out work on the work position (7) indicated by the visible light (8) from the work position indicator (3). The tool position detector (36) is configured to detect a relative position of the electric tool (2) with respect to the work position (7). The tool position decider (384) is configured to decide whether or not the electric tool (2) is set on the work position (7) with reference to a detection result by the tool position detector (36) before the electric tool (2) carries out the work on the work position (7).
