Machine Tool Observation Data Printing With Variable Time Scales
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited display area on measuring units for industrial machines makes it difficult to view detailed waveforms of observation data across all time periods, as existing techniques only allow for enlargement of specific sections or time axes, hindering comprehensive analysis.
Innovation Solution
An observation device and method that acquires observation data, sets a time scale based on amplitude or frequency, and generates print data for output to a printing device, allowing for detailed examination of machine tool or industrial machine data across all time periods by adjusting the time scale according to data intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If observation data about one machining is displayed in entirety on a limited display area, then all time periods can be viewed, but detailed waveform sections become difficult to check
Solution Approach 1:
The patent applies dynamic time scale adjustment by allowing the time axis to be selectively enlarged for specific sections. The control unit dynamically changes the display magnification based on user selection, transforming the static display into a dynamic system that can adapt between overview and detailed views as needed.
Solution Approach 2:
The patent segments the observation data display into multiple time scale sections. By dividing the time axis into selectable segments, users can focus on specific portions of the waveform at enlarged scales while maintaining context from other sections, effectively resolving the conflict between overall visibility and detailed inspection.
2Measurement precision
If waveform is enlarged by changing display time axis, then dense section can be checked in detail, but observation data about one machining cannot be viewed at a glance
Solution Approach 1:
The patent introduces a temporal dimension to the display system by implementing multi-time-scale capability. Instead of a single linear time axis, the system allows simultaneous representation of multiple time scales, enabling users to view both overall machining context and detailed waveform sections within the same display space.
Solution Approach 2:
The display is segmented into multiple time scale sections that can be independently adjusted. This segmentation allows the overall machining data to be displayed at a reduced time scale for context, while specific sections of interest can be enlarged for detailed inspection, preventing information loss at any scale.
3Device complexity
If display area is limited, then device complexity is reduced, but comprehensive analysis of observation data is hindered
Solution Approach 1:
The patent implements dynamic time scale control that allows the display system to adapt its complexity on demand. The control unit provides simple overview display by default, but can dynamically enlarge specific time sections when users select them, enabling comprehensive analysis without permanently increasing device complexity.
Solution Approach 2:
The system provides self-service by automatically adjusting the time scale based on user selection. When a user selects a specific time section, the control unit autonomously enlarges that section and adjusts the display accordingly, eliminating the need for complex manual configuration while enhancing analysis capability.
