Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric power tools face difficulties in changing operating conditions due to the need to manually find settable items and ranges, leading to cumbersome preparation and potential incorrect settings.
Innovation Solution
An apparatus that allows users to easily change operating conditions using an external device, with a controller that notifies and corrects settings within settable ranges, preventing incorrect changes and improving usability through near field wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually find settable items and ranges through manuals or manufacturer websites, then they can change operating conditions, but the preparation process becomes burdensome and time-consuming
Solution Approach 1:
The communication device provides feedback to the external device about the settable items and ranges of operating conditions. This feedback mechanism allows the external device to automatically understand what parameters can be adjusted and within what ranges, eliminating the need for users to manually search through manuals or websites before making settings changes.
2Ease of operation
If users manually find settable items and ranges, then they can change operating conditions, but the process requires cumbersome preparation
Solution Approach 1:
The system performs self-service by automatically providing information about settable items and ranges to the external device. The communication device autonomously transmits the necessary setting information without requiring the user to manually search for it, thereby simplifying the overall setting process and reducing user burden.
Solution Approach 2:
The communication device acts as an intermediary between the power tool and the external device. It facilitates automatic communication of settable parameters and ranges, eliminating the need for users to directly search through manuals or websites, thus reducing the complexity of the setting process.
3Adaptability or versatility
If users change operating conditions using external devices without automatic notification, then settings can be modified, but incorrect settings may occur
Solution Approach 1:
The communication device provides feedback to the external device regarding the settable ranges of operating conditions. This feedback enables the external device to automatically validate and correct setting values within acceptable ranges, preventing incorrect settings while maintaining the flexibility to adjust various operating parameters.
Solution Approach 2:
The system performs preliminary action by pre-defining and communicating the settable ranges of operating conditions before the actual setting process. This allows the external device to automatically validate and correct setting values within acceptable ranges, preventing incorrect settings before they occur.
