Solution Overview
Problem
Existing table generating apparatus, such as scientific calculators, are inconvenient for generating tables of multiple ranges and require users to reset the range settings to add new ranges, making it difficult to efficiently analyze functions and graphs with multiple feature points.
Innovation Solution
A table generating apparatus with a processor and display unit that allows users to input function expressions, set table ranges, generate and display tables, receive additional values, and expand the table range by adding corresponding values determined by the function expression, enabling easy widening of the table range without resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a table generating apparatus generates a table of one range only, then the device complexity is reduced and operation is simplified, but the adaptability to generate tables of multiple different ranges is poor
Solution Approach 1:
The table generating apparatus is designed to perform multiple functions: it can generate tables for a single range initially set, and also expand to generate tables for multiple different ranges by sequentially adding adjacent ranges. This multi-functionality allows the same device to handle both simple single-range table generation and complex multi-range table generation without requiring different devices or complex reconfiguration.
Solution Approach 2:
The apparatus transitions from a static single-range table generation mode to a dynamic multi-range table generation mode. The table range is not fixed but can be expanded sequentially by adding adjacent ranges. This dynamic capability allows the table range to adapt to user needs while maintaining operational simplicity through automated range expansion.
2Productivity
If the apparatus requires resetting the range setting to add another range, then the range setting control is simplified, but the time required to generate tables of multiple ranges increases
Solution Approach 1:
The apparatus performs preliminary actions by maintaining the initially set table range and using it as a basis for subsequent range expansions. Instead of requiring complete resetting, the system preserves the initial range settings and builds upon them by sequentially adding adjacent ranges, thereby eliminating the time-consuming reset process while maintaining controlled range setting.
Solution Approach 2:
The table generation process maintains continuity by seamlessly expanding from the initial table range to multiple ranges without interruption or resetting. The system continuously adds adjacent ranges to the existing table, allowing users to efficiently generate tables of multiple ranges in a single continuous operation rather than repeatedly stopping to reset settings.
3Adaptability or versatility
If the apparatus generates only a single table range, then the ease of operation is improved, but the ability to analyze functions with multiple feature points is reduced
Solution Approach 1:
The analysis of functions with multiple feature points is achieved by segmenting the overall range into multiple adjacent sub-ranges. Each sub-range can be generated as a separate table, allowing detailed analysis of specific feature points while maintaining ease of operation through systematic range division. This segmentation enables focused analysis without requiring complex multi-range table generation.
Solution Approach 2:
The apparatus adds a dimensional aspect to table generation by enabling expansion from a single range to multiple ranges. This dimensional change allows users to analyze multiple feature points across different ranges while maintaining the simplicity of single-range operation for each individual table, effectively adding the capability dimension without sacrificing operational ease.

AI summary
A table generating apparatus includes a display unit and a processor which performs the following processes of: receiving an input of a function expression; receiving an input for setting a table range; generating a table representing a relation between a plurality of values in the range and their corresponding values determined by the function expression based on the table range, displaying the generated table on the display unit; receiving an input of an additional value while the table is displayed; adding the received additional value and its corresponding value determined by the function expression to the displayed table; and expanding the table by adding values obtained by subsequently changing the additional value and their corresponding values determined by the function expression to the displayed table, after the table addition function adds the additional value and its corresponding value to the table, each time an operation input is received.
