Power Tool Motor Parameter Recording for Repeatable Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power tools lack the ability to record and playback motor parameters, limiting user customization and efficiency in operating modes.
Innovation Solution
A power tool with a mode selector switch and controller that allows users to select between recording, playback, and normal operating modes, enabling the recording of motor parameters during use and playback of those parameters for consistent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power tools operate in normal mode only, then the device complexity is low, but the adaptability and user customization capability are limited
Solution Approach 1:
The power tool is designed with multiple operating modes (recording mode, playback mode, and normal operation mode) within a single device, allowing it to perform diverse functions. The controller can record motor parameters during recording mode and replay them during playback mode, making the tool adaptable to different operational requirements while maintaining a unified device structure.
Solution Approach 2:
The system performs preliminary recording of motor parameters during recording mode before actual operation is needed. This allows the tool to capture optimal performance data in advance, which can then be replayed to ensure consistent operation without requiring complex real-time adjustments during normal use.
2Productivity
If motor parameters are recorded and played back, then operational consistency and efficiency are improved, but the loss of time for recording and setup increases
Solution Approach 1:
The system creates a digital copy of motor parameters during recording mode and stores them in memory. This copy can be replayed multiple times without requiring additional recording time, allowing the original recording to be reused for consistent operation while minimizing the time investment required for setup.
Solution Approach 2:
The motor parameters are recorded in advance during recording mode, allowing the actual operation to proceed without time loss. The preliminary recording captures all necessary operational data, which can then be replayed instantly during playback mode without requiring repeated setup or adjustment time.
3Adaptability or versatility
If multiple operating modes are implemented, then user customization and performance optimization are enhanced, but the ease of operation decreases due to mode selection complexity
Solution Approach 1:
The system provides feedback to the user through indicators that show which operating mode is currently active (recording mode, playback mode, or normal operation mode). This feedback mechanism helps users understand the current state and makes mode selection more intuitive, reducing the complexity associated with multiple operating modes.
Solution Approach 2:
The mode selection functionality is extracted as a separate control feature, allowing users to switch between recording, playback, and normal operation modes independently. This separation simplifies the user interface by dedicating specific controls to mode selection, making the overall operation easier despite the multiple functions available.
Data Source
AI summary
A power tool and method for recording and playing back a motor parameter. The power tool includes a housing, a motor, a trigger, and a controller. The trigger outputs an activation signal based on a user input. The controller receives a user mode selection signal indicating a selected mode. The controller enters the recording mode when the user mode selection indicates the recording mode, and records a motor parameter to generate a recorded motor parameter. The recorded motor parameter covers a first time period in which motor is operating in response to depression of the trigger, a second time period in which motor is inactive in response to release of the trigger, and a third time period in which motor is operating in response to another depression of the trigger. In the playback mode, the controller operates the motor based on the recorded motor parameter upon receiving the activation signal.
