Problem
Users of scientific calculators face difficulties in efficiently using copied formulas due to the need to manually delete and replace parameter portions with desired numerical values, which is time-consuming and error-prone.
Innovation Solution
A formula display control device with a template formula generation unit that replaces coefficient and argument portions with input frames, allowing users to generate and display template formulas, enabling easy input of numerical values and simplifying the use of copied formulas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually delete and replace parameter portions in copied formulas, then they can input desired numerical values, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system performs preliminary action by automatically detecting coefficient portions in the copied formula and replacing them with input frames before the user needs to input values. This pre-processing eliminates the need for users to manually delete parameter portions, directly resolving the contradiction by saving time while maintaining ease of operation.
2Ease of operation
If users manually delete and replace parameter portions in copied formulas, then they can input desired numerical values, but the process becomes error-prone
Solution Approach 1:
The system implements self-service by automatically identifying coefficient portions and replacing them with appropriately positioned input frames. This automated process eliminates manual deletion operations that users might perform incorrectly, thereby improving reliability while maintaining ease of operation. The system serves itself by detecting and preparing the formula structure without user intervention.
3Productivity
If the system replaces coefficient portions with input frames, then users can easily input numerical values, but the device complexity increases
Solution Approach 1:
The system applies parameter changes by dynamically modifying the formula structure - specifically replacing coefficient portions with input frames. This transformation is achieved through automated detection and replacement operations that change the parameters of the formula representation. The complexity is managed by focusing on specific parameter changes (coefficient identification and replacement) rather than comprehensive formula restructuring.

AI summary
A formula display control device includes a display unit, a text display control unit, a formula designation unit, a template formula generation unit and a template formula display control unit. The text display control unit displays text including a formula on the display unit. The formula designation unit designates the formula in the text displayed on the display unit in response to a user operation. The template formula generation unit replaces a coefficient portion in the formula with an input frame to generate a template formula when a coefficient is included in the designated formula. The template formula display control unit displays the template formula generated by the template formula generation unit as text which is displayed on the display unit.
