Curve Extension for Complete Character String Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices cannot fully display a character string along a curve when the curve's length is shorter than the string's length, resulting in incomplete display of the character string.
Innovation Solution
An input display control device that acquires curve information and a character string, determines if the curve is too short, and extends its shape to generate display information for displaying the entire character string by extending the curve, ensuring the character string is fully visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the curve length is kept as is, then the display device is simple, but the character string cannot be fully displayed when the curve is shorter than the string
Solution Approach 1:
The system performs preliminary detection of whether the curve length is sufficient before display, and pre-calculates the extended curve shape based on the original curve's characteristics. This allows the system to prepare the extended curve in advance, ensuring complete character string display without requiring complex real-time adjustments during rendering.
Solution Approach 2:
The system changes the curve length parameter by extending it while maintaining the original curve's shape characteristics. By calculating an extended curve that preserves the original curvature and visual properties, the system increases the curve length to accommodate the full character string without fundamentally altering the display approach or requiring complex new algorithms.
2Reliability
If the curve is extended to accommodate the character string, then complete display is achieved, but the original curve shape is modified
Solution Approach 1:
The system calculates the extended curve shape in advance based on the original curve's geometric characteristics, preserving the visual appearance of the original curve while creating a mathematically extended version that provides sufficient length for the complete character string display.
Solution Approach 2:
The system extends the curve by modifying the length parameter while maintaining the shape parameters of the original curve. The extended curve is generated to follow the same geometric pattern and curvature characteristics, ensuring the original shape is preserved visually while providing the necessary additional length.
3Loss of information
If the entire character string is displayed along the curve, then information completeness is improved, but the display area requirement increases
Solution Approach 1:
The system transitions from displaying only the portion of the character string that fits within the original curve bounds to displaying the entire string by extending into additional spatial dimension along the curve's path. This allows complete information display while maintaining efficient use of the display area by following the curve's natural trajectory.

AI summary
A display control unit determines, in a case of determining that a part of a character string acquired by a character string acquiring unit cannot be displayed along a curve indicated by curve information acquired by a curve information acquiring unit because the length of the curve is short, a shape of an extended part of the curve from a shape of the curve indicated by the curve information acquired by the curve information acquiring unit, extends the curve, and generates display information for displaying the part of the character string along the curve of the extended part.
