Portable Tool Control Unit Dynamic Restriction Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool systems, such as those described in Patent Literature 1, often restrict tool operations when a work target does not conform to a defined working procedure, limiting flexibility for tasks like re-tightening fastening members or performing irregular work.
Innovation Solution
A tool system comprising a portable tool with a driving unit, an image capturing unit, and a control unit that supports work operations by identifying work targets through captured images and enforcing working procedures. The control unit places restrictions on tool operations if the work target does not conform to the procedure but lifts these restrictions when a lifting condition is met, allowing for more flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control unit places restrictions on tool operations when the work target does not conform to the working procedure, then the reliability of the working procedure is improved, but the adaptability of the tool system deteriorates
Solution Approach 1:
The control unit dynamically adjusts the operation restriction state based on detected lifting conditions. When a lifting condition is satisfied (such as specific tool operations or user inputs), the system transitions from a restricted state to an unrestricted state, allowing flexible adaptation while maintaining procedural reliability during normal operation
Solution Approach 2:
The system changes the operational parameters of the tool by switching between restricted and unrestricted operation modes. This parameter change allows the system to maintain strict procedural compliance under normal conditions while enabling exceptional operations when lifting conditions are met
2Manufacturing precision
If the control unit restricts tool operations to enforce working procedures, then the manufacturing precision of work targets is improved, but the ease of operation deteriorates
Solution Approach 1:
The operation restriction is implemented dynamically rather than statically. The system automatically adjusts its control level based on whether lifting conditions are satisfied, providing precise control during standard operations while enabling flexible operation when needed
Solution Approach 2:
The control unit continuously monitors operational conditions and automatically adjusts restriction levels based on feedback from detected lifting conditions. This feedback mechanism ensures precision is maintained when required while allowing ease of operation when lifting conditions are met

AI summary
A tool system includes a portable tool, an image capturing unit, and a control unit. The tool includes a driving unit to be activated with power supplied from a power source. The image capturing unit is provided for the tool and generates a captured image. The control unit controls the tool based on the captured image. The control unit has a work support capability. The work support capability is the capability of placing a restriction on operation of the tool when a work target identified based on the captured image does not conform to a working instruction defined by a working procedure. The control unit suspends, when finding a lifting condition satisfied while performing work-support-enabled operation, the work-support-enabled operation and thereby lifts the restriction on the operation of the tool.
