Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a calculator is used for calculations, then portability and ease of operation are improved, but the ability to display complex calculations and graphs deteriorates
Solution Approach 1:
The patent introduces a terminal device (smartphone, tablet, or PC) as an intermediary between the calculator and the user. The calculator transmits calculation formula information to the terminal device, which then displays graphs and provides calculation assistance. This mediator resolves the contradiction by allowing the calculator to remain simple and portable while the terminal device handles complex display requirements.
2Adaptability or versatility
If Internet services are accessed from a calculator, then calculation functions are improved, but device complexity increases
Solution Approach 1:
The terminal device serves as an intermediary that accesses Internet services and calculation databases on behalf of the calculator. The calculator maintains its simplicity while the terminal device handles the complexity of Internet connectivity, data processing, and graph generation. This allows enhanced calculation functions without increasing the calculator's device complexity.
3Productivity
If automatic calculation assistance is provided, then productivity is improved, but device complexity increases
Solution Approach 1:
The system implements automatic calculation assistance where the calculator automatically transmits calculation formula information to the terminal device without requiring user intervention. The terminal device automatically determines whether assistance is needed and provides appropriate assistance information. This self-service mechanism improves productivity while distributing complexity to the terminal device rather than the calculator.
