Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graph scientific electronic calculators face difficulties in precisely varying the coefficient value of a function expression within a predetermined range, making it challenging to accurately display the corresponding graph image, especially when the coefficient value needs to be set to a specific numerical value.
Innovation Solution
A graph display control apparatus that includes a function expression display control unit, coefficient value variation range setting unit, and operation display elements such as sliders for varying the coefficient value, allowing users to easily and quickly adjust the coefficient within a preset range and re-display the graph image based on the varied coefficient value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coefficient value is varied within a predetermined variation interval using a slider, then the graph image can be displayed dynamically, but the coefficient value cannot be precisely set to a specific numerical value
Solution Approach 1:
The coefficient value variation is divided into two stages: a coarse variation stage using a first slider to adjust the coefficient within a predetermined variation interval, and a fine adjustment stage using a second slider to precisely set the coefficient to a target value. This segmentation allows users to first broadly adjust the coefficient and then make precise adjustments, resolving the contradiction between ease of operation and measurement precision.
Solution Approach 2:
The system dynamically switches between two different slider mechanisms based on the current state of coefficient value adjustment. The first slider provides coarse adjustment with a larger step size, while the second slider provides fine adjustment with a smaller step size. This dynamic adaptation of the adjustment mechanism allows users to efficiently reach the target coefficient value while maintaining precision.
2Measurement precision
If the numerical value variation amount corresponding to one display dot of the tab is set finely, then the coefficient value can be precisely set, but the coefficient value cannot be varied largely
Solution Approach 1:
The coefficient value adjustment range is segmented into two parts: a large variation range handled by the first slider with coarse adjustment steps, and a small precision range handled by the second slider with fine adjustment steps. This segmentation allows the system to both vary the coefficient value largely and set it precisely, as each slider is optimized for its specific range.
Solution Approach 2:
The first slider performs a preliminary coarse adjustment to bring the coefficient value close to the target value within a large range. Only after this preliminary action does the system engage the second slider for precise fine adjustment. This preliminary action eliminates the need for the second slider to handle the entire range, allowing it to focus on precision within a small range.
3Measurement precision
If a dedicated screen for setting coefficient value is displayed, then the coefficient can be adjusted, but the operation process becomes complex
Solution Approach 1:
The patent merges the coefficient value adjustment function with the existing graph display interface. Instead of requiring a separate dedicated screen, the first and second sliders are integrated into the graph display environment, allowing users to adjust the coefficient value while viewing the corresponding graph image. This merging reduces the operational complexity by eliminating the need to switch between different screens.
Solution Approach 2:
The graph display interface is enhanced with multi-functionality to serve both graph visualization and coefficient value adjustment. The first and second sliders are superimposed on the graph display area, allowing users to perform both graph viewing and coefficient adjustment within a single interface. This universal interface reduces the number of separate operations needed.
