Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional UWB pulse train generator is used, then UWB pulse train generation is achieved, but integration with digital SOC systems is difficult and construction is complex
Solution Approach 1:
The generator is divided into three independent functional modules: trigger signal controller, latch unit, and pulse train generator. Each module performs a specific function and can be independently designed and integrated, making the overall system easier to manufacture and integrate with digital SOC while maintaining manageable complexity
Solution Approach 2:
The latch unit serves multiple functions: it stores n-bit data, sequentially toggles the stored data in response to trigger signals, and outputs the toggled data to the pulse train generator. This multi-functionality reduces the number of separate components needed, simplifying the overall construction and improving ease of integration
2Reliability
If sequential triggering is implemented for n-bit data, then complete UWB pulse train generation is achieved, but power consumption increases
Solution Approach 1:
The latch unit sequentially toggles the stored n-bit data in periodic response to trigger signals, with each bit being toggled at a predetermined time period. This periodic action ensures complete and accurate pulse train generation while allowing the system to remain in a low-power state between triggering events, thus balancing reliability with reduced power consumption
