Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction laser operation methods, particularly with remote control units, are not intuitive and often result in unintentional device movements, leading to malfunctions and user discomfort due to complex handling and the need for frequent movement between the user and the laser device.
Innovation Solution
A method where actions on a construction laser are only triggered after a threshold value of parameter change is reached, with the extent of the action changing proportionally to the parameter change, using sensors like inclination sensors to ensure intentional movements are detected, thereby preventing unintentional actions and simplifying the operation of modes like scan, section, and point modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If actions are triggered immediately by pressing control panel buttons, then operation response is fast, but unintentional movements cause malfunctions and reduce reliability
Solution Approach 1:
The system performs preliminary detection of movement intensity using acceleration sensors before triggering actions. The control method evaluates whether the detected acceleration exceeds a threshold value, and only then processes the button press as a valid command. This preliminary verification prevents unintentional operations while maintaining fast response for intentional actions.
Solution Approach 2:
The system continuously monitors acceleration data from sensors and provides feedback to the control logic. When a button is pressed, the system checks the current acceleration state against threshold criteria, creating a feedback loop that distinguishes intentional from unintentional movements. This feedback mechanism ensures reliable operation without sacrificing response speed.
2Reliability
If remote control unit requires complex handling procedures, then unintentional movements are prevented, but ease of operation deteriorates and user comfort decreases
Solution Approach 1:
The system changes the parameter evaluation from simple button press detection to acceleration-threshold-based validation. By monitoring the intensity and characteristics of device movement through acceleration sensors, the system automatically distinguishes intentional from unintentional actions. This parameter change simplifies the user interface while maintaining reliability, as users naturally move the remote control with sufficient intensity during intentional operation.
Solution Approach 2:
The remote control unit automatically performs validation of user intentions through its built-in acceleration sensors and control logic. The system self-determines whether a button press is intentional by evaluating movement parameters, eliminating the need for complex manual verification procedures. This self-service approach maintains reliability while preserving ease of operation.
3Reliability
If threshold-based action triggering is implemented, then unintentional movements are prevented, but device complexity increases due to additional sensors and control logic
Solution Approach 1:
The acceleration sensors serve multiple functions: they detect unintentional movements for reliability validation, characterize intentional movements for action triggering, and can potentially provide additional information about user intent. This multi-functionality reduces the need for separate validation mechanisms, thereby limiting the increase in device complexity while maintaining improved reliability.
4Ease of manufacture
If user must move between laser device and control panel, then direct device adjustment is possible, but loss of time increases and productivity decreases
Solution Approach 1:
The control functionality is extracted from the laser device itself and placed into a separate remote control unit that the user can carry freely. This extraction allows the user to operate the laser device from any position without physical contact, eliminating the need to move between the laser and control panel. The acceleration-based validation ensures that this remote operation maintains the same reliability as direct device adjustment.
