Surface Texture Measuring Device Drawing Symbol Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface texture measuring devices are complicated to set up due to the requirement for users to understand the relationships between drawing symbols and setting symbols, leading to potential entry errors.
Innovation Solution
A surface texture measuring device with a display control unit to show a drawing symbol entry screen, an entry acceptance unit to input drawing symbols, and an arithmetic unit to calculate surface texture information, allowing users to directly enter symbols without needing to understand the relationships between them, along with a converter to switch between drawing and setting symbols, an input condition decider to detect errors, and a guide unit to explain symbol content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users enter setting symbols directly based on drawing symbols, then measurement setup can be completed, but user understanding of relationships between drawing symbols and setting symbols is required leading to complicated operation and potential entry errors
Solution Approach 1:
The patent introduces a drawing symbol entry screen that serves as an intermediary interface between the user and the internal setting symbols. Users input drawing symbols (which are standardized and visually intuitive) rather than directly inputting internal setting symbols. The system automatically converts these drawing symbols into the corresponding setting symbols, eliminating the need for users to understand complex relationships between different symbol systems and reducing entry errors.
Solution Approach 2:
The patent uses drawing symbols (which are standardized graphical representations) as the input interface instead of requiring users to input abstract setting symbols. The drawing symbol entry screen displays and accepts input of these standardized drawing symbols, which are then converted into the internal setting symbols. This copying approach allows users to work with familiar, visual symbols rather than abstract parameters.
2Adaptability or versatility
If multiple entry screens (drawing symbol and setting symbol) are provided, then users can choose their preferred entry method, but device complexity increases
Solution Approach 1:
The patent implements a universal entry system where the drawing symbol entry screen serves multiple functions: it accepts user input, performs validation, converts drawing symbols to setting symbols, and can switch to a setting symbol entry screen when needed. This multi-functional design allows the system to adapt to different user preferences and requirements without requiring completely separate input systems, thereby managing complexity while maintaining versatility.
Solution Approach 2:
The patent provides a dynamic entry system where users can switch between drawing symbol entry and setting symbol entry modes based on their needs. The system adapts its interface requirements dynamically - using drawing symbols for normal operation and allowing setting symbol entry when users need more direct control or when drawing symbols are insufficient. This dynamic approach maintains flexibility while keeping the interface manageable.

AI summary
A surface texture measuring device comprises a display control unit operative to display a drawing symbol entry screen having entry areas of drawing symbols. An entry acceptance unit is provided to accept the input of the drawing symbol into the entry area provided in the drawing symbol entry screen. An arithmetic unit is provided to calculate surface texture information that indicates a surface texture of an object to be measured, from the measurement result of surface displacements of the object, based on the drawing symbol accepted at the entry acceptance unit.
