Surface Texture Measuring Interface for Accidental Touch Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measuring devices that allow measurement conditions to be set through a touch panel are prone to incorrect settings due to accidental touches, complicating the measurement process with the need for frequent enabling and disabling of the touch panel.
Innovation Solution
A measuring device with a touch panel that can be switched between enabled and disabled states, allowing measurement conditions to be set through a key group when the touch panel is disabled, preventing accidental inputs and enabling easy condition changes without errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel is enabled to allow measurement condition setting, then the ease of operation is improved, but the reliability deteriorates due to accidental touches causing incorrect settings
Solution Approach 1:
The touch panel dynamically changes its state between enabled and disabled based on the measurement condition setting process. The control unit switches the touch panel to a disabled state when a measurement condition is being set, preventing accidental touches during critical operations, and enables it again when setting is complete, maintaining ease of operation when appropriate.
2Reliability
If the touch panel is disabled to prevent incorrect settings, then the reliability is improved, but the ease of operation deteriorates due to the need for frequent enabling and disabling
Solution Approach 1:
The control unit proactively disables the touch panel in advance before the measurement condition setting process begins, and re-enables it after setting completes. This preliminary action prevents the need for frequent manual switching by the operator, maintaining reliability while reducing operational complexity.
3Reliability
If the touch panel state is frequently switched to prevent errors, then the reliability is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The control unit performs multiple functions: it manages the overall measurement process, processes operator inputs, and simultaneously controls the touch panel enable/disable state based on the measurement condition setting status. This multi-functionality eliminates the need for separate control mechanisms, maintaining reliability while avoiding increased device complexity.

AI summary
A surface texture measuring machine includes a display section, a touch panel arranged on the display section, a key group, a display control section that causes a first setting screen to be displayed on the display section, a setting section that creates a measurement condition in accordance with an input operation on the first setting screen through the touch panel, a storage that stores the measurement condition, and an input control section that switches a state of the touch panel between a disabled state and an enabled state. When the touch panel is in the disabled state, the display control section causes a second setting screen to be displayed on the display section in accordance with the input operation through the key group and the setting section reads the measurement condition from the storage in accordance with the input operation on the second setting screen through the key group.
