Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a voltage source with high internal resistance is used to supply both lighting means and additional consumers, then the lighting function is achieved, but voltage fluctuations occur causing brightness instability and unreliable operation
Solution Approach 1:
The patent segments the power supply system into two independent paths: a constant current circuit path for lighting means and a bypass circuit path for additional consumers. This segmentation allows each path to operate independently without interfering with the other, resolving the voltage stability issue while maintaining versatility.
Solution Approach 2:
The patent introduces a bypass circuit as an intermediary element that mediates between the voltage source and additional consumers. This bypass circuit provides a dedicated current path that isolates consumers from voltage fluctuations, enabling reliable consumer operation while maintaining lighting performance.
2Illumination intensity
If a constant current circuit is used to supply lighting means, then brightness stability is improved, but additional consumers experience voltage fluctuations and unreliable operation
Solution Approach 1:
The power supply is segmented into separate constant current path for lighting and bypass path for consumers. This segmentation allows the constant current circuit to maintain stable lighting while the bypass circuit independently supplies consumers, eliminating the trade-off between lighting stability and consumer reliability.
Solution Approach 2:
The bypass circuit acts as an intermediary that provides stable power to additional consumers without interfering with the constant current supply to lighting means. This mediator circuit enables both functions to operate reliably simultaneously.
3Adaptability or versatility
If consumers requiring pulsed currents are connected to a soft voltage source, then additional functionality is achieved, but voltage collapse occurs causing instability in the energy source
Solution Approach 1:
The patent segments the current supply by providing a dedicated bypass circuit path for consumers requiring pulsed currents. This segmentation allows consumers to draw pulsed current while the constant current circuit maintains stable lighting supply, preventing voltage collapse and maintaining energy source stability.
Solution Approach 2:
The bypass circuit serves as an intermediary that handles the pulsed current demands of additional consumers, isolating these fluctuations from the main voltage source and constant current circuit. This mediator prevents voltage collapse while enabling consumer functionality.
