Solution Overview

Problem

Conventional calculators have limited display capacity, making it difficult to effectively show multiple related numerical values, especially in specialized calculations like medical calculations, where precise and multiple values need to be displayed simultaneously.

Innovation Solution

An electronic apparatus with a processor-driven display system that allows switching between multiple numerical values, using a combination of dot matrix and 7-segment displays to efficiently show calculation results, such as the powdered medicine package calculation, by determining if values can be displayed in one line or requiring sequential display of lower and upper limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple numerical values are displayed in parallel by dividing the display region into multiple rows, then the display capacity is increased, but the display size increases and the device complexity increases

Engineering Contradiction:
Improvedisplay capacityVSAvoiddisplay structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The display dynamically switches between displaying multiple numerical values in parallel and displaying them sequentially, allowing the display structure to adapt its configuration based on the calculation context and user needs, thereby maintaining display capacity while reducing structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display region is segmented into multiple areas that can be independently controlled, allowing the system to selectively activate single-line or multi-line display modes based on the number of numerical values to be displayed, thus optimizing between capacity and complexity

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple numerical values are displayed in parallel by dividing the display region into multiple rows, then the display capacity is increased, but the display size increases

Engineering Contradiction:
Improvedisplay capacityVSAvoiddisplay size
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The display employs dynamic switching between single-line and multi-line display modes, allowing the same physical display area to serve different functions - displaying multiple values sequentially when space is constrained, and in parallel when capacity is prioritized, thus decoupling display capacity from display size

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display uses periodic switching between different display configurations (single-line vs multi-line, parallel vs sequential), enabling the limited display area to present multiple numerical values over time through controlled alternation, effectively increasing capacity without expanding physical size

Inventive Principle:
Principle #19Periodic action

AI summary

An electronic apparatus includes a display and at least one processor for executing a program stored in a storage. The at least one processor displays a calculation result of an executed calculation. In a case where the calculation result includes a plurality of numerical values that are related to each other, the at least one processor displays the plurality of numerical values on the display in such a manner as to be able to switch between each numerical value.
