Solution Overview
Problem
Existing graph display devices face difficulties in appropriately setting and outputting data, including function formulas, to external devices, often due to limitations in data capacity, making it challenging to display graph images correctly.
Innovation Solution
An electronic device with a processor that performs formula input, setting, extraction, and output processes, allowing users to input and set formula data, extract referenced data, and output it to external devices, enabling proper display of graph images by converting data into 2D codes like QR codes for transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If function formula data is output to external devices, then graph images can be displayed externally, but data capacity limitations make it difficult to set and output appropriate data
Solution Approach 1:
The patent segments formula data into individual components (function formulas, graph images, parameters) that can be independently selected and output. The system divides the complete data set into manageable units that fit within external device memory constraints, allowing selective transmission of only necessary data elements.
Solution Approach 2:
The patent extracts and outputs only the essential function formula data needed for graph display, separating critical information from redundant data. The system identifies and extracts key parameters and formula definitions while omitting unnecessary auxiliary data, thereby reducing overall data volume while maintaining display functionality.
2Manufacturing precision
If complete formula data is output, then external devices can display graph images accurately, but data volume exceeds output capacity limitations
Solution Approach 1:
The patent creates simplified copies of formula data that retain essential display characteristics while reducing data volume. Instead of transmitting complete high-precision mathematical definitions, the system generates condensed representations that preserve graph image accuracy within the constraints of external device processing capabilities.
3Adaptability or versatility
If graph display device has wired or wireless communication functions, then data can be output externally, but device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary data processing system that bridges the graph display device and external devices. This intermediary handles the complex communication and data conversion tasks, allowing the graph display device itself to remain simple while still achieving external data output through the mediating system.
