Solution Overview

Problem

Conventional electronic devices, such as calculators, lack the ability to perform arithmetic operations using data received from external devices, making it difficult for users to determine if they have received data from external sources, especially in cooperative scenarios with smart devices.

Innovation Solution

An electronic device equipped with a communication unit, input device with hardware keys, and an output device that provides notice when numerical data is received for arithmetic operations, allowing data communication with external devices and visualizing the data received from smart devices through a display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an electronic device like a calculator is used in cooperation with a smart device to perform arithmetic operations, then the utility value and functionality of the electronic device improves, but it becomes difficult for the user to know whether the electronic device received data from the external smart device

Engineering Contradiction:

Improvecooperative functionality with smart deviceVSAvoiduser awareness of received data

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the electronic device provides visual notification to the user when numerical data is received from an external smart device. The notification is displayed on the device's screen, creating a closed-loop information flow that confirms data reception and maintains user awareness during cooperative operations between the calculator and smart device.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If conventional electronic devices are designed to perform only local arithmetic operations, then the device structure remains simple and reliable, but the device cannot perform complex arithmetic operations that require cooperation with external smart devices

Engineering Contradiction:

Improvearithmetic operation capabilityVSAvoiddata reception and notification system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables the electronic device to perform multiple functions: traditional local arithmetic operations using hardware keys and enhanced cooperative arithmetic operations with external smart devices. The device universally handles both standalone calculations and networked collaborative calculations, allowing users to switch between different operational modes depending on their needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The notification system acts as an intermediary component that bridges the data reception function and the user interface. When numerical data is received from an external smart device, the notification mechanism mediates by displaying a visual alert on the screen, ensuring the user is informed without requiring complex additional hardware or interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)
