Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If rapid and huge data transmission technology is adopted, then data transmission speed is improved, but device complexity and cost increase
Solution Approach 1:
The patent changes the data transmission parameter from high-frequency RF signals to low-frequency signals (e.g., audio frequency range), which allows simple circuit implementation while maintaining adequate transmission speed for interactive applications. This parameter change resolves the contradiction by sacrificing excessive speed for simplicity.
Solution Approach 2:
The patent employs inexpensive components such as simple oscillators, modulators, and detectors that can be easily manufactured and replaced. These simple circuits use basic electronic components rather than complex integrated circuits, reducing both cost and complexity while achieving the required functionality for temporary or disposable interactive devices.
2Loss of information
If complex circuits are used for signal processing, then data transmission capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the data transmission system into three simple functional segments: signal generation (oscillator), signal modulation (modulator), and signal detection (detector). Each segment uses independent, simple circuits that can be manufactured separately and assembled, reducing overall manufacturing cost while maintaining complete data transmission capability.
Solution Approach 2:
The patent replaces complex electronic signal processing with simpler analog modulation and detection techniques. Instead of using complex digital signal processing circuits, the system uses analog carrier wave modulation and envelope detection, which can be implemented with simple RC circuits and diodes, significantly reducing manufacturing cost.
3Speed
If high-frequency RF circuits are used, then data transmission speed is improved, but device complexity and cost increase
Solution Approach 1:
The patent fundamentally changes the operating frequency parameter from high-frequency RF range to low-frequency audio range, allowing the use of simple RC oscillators and analog modulators instead of complex RF synthesizers and amplifiers. This parameter change maintains sufficient transmission speed for interactive applications while dramatically reducing circuit complexity.
