Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the output voltage of the energiser is increased to compensate for fence losses, then the effective fence voltage is maintained, but energy losses increase exponentially and safety risks increase
Solution Approach 1:
The patent implements dynamic adjustment of energiser output voltage based on real-time fence conditions. The controller continuously monitors fence voltage and adjusts the output voltage dynamically rather than operating at a fixed high voltage, thereby maintaining effectiveness while minimizing energy losses and safety risks.
Solution Approach 2:
The patent employs a feedback control system where the controller monitors fence voltage and uses this information to adjust the energiser output. This closed-loop feedback mechanism enables the system to maintain minimum effective voltage without excessive voltage increases, optimizing energy efficiency and safety.
2Device complexity
If a single energiser serves the entire fence, then device complexity is reduced, but energy losses along the fence cannot be selectively minimized
Solution Approach 1:
The patent divides the fence into multiple zones with different energisers or switching arrangements, allowing selective control of energy output to different sections. This segmentation enables the system to address localized loading issues without increasing overall system complexity significantly, as each zone can be independently optimized.
Solution Approach 2:
The patent applies different energy levels or switching strategies to different portions of the fence based on local conditions. By providing tailored energy delivery to specific zones rather than uniform coverage, the system minimizes energy losses in areas with high loading while maintaining effectiveness elsewhere.
3Loss of energy
If real-time measurement and adjustment of fence energy losses is implemented, then energy efficiency is improved, but device complexity and control algorithm requirements increase
Solution Approach 1:
The patent implements a feedback control system with sensors that continuously monitor fence voltage and energy losses. This real-time feedback enables precise measurement of energy losses and automatic adjustment of energiser output, improving energy efficiency while managing complexity through automated control algorithms.
Solution Approach 2:
The patent enables the fence system to self-monitor and self-adjust its energy delivery. The control system automatically detects energy losses and modifies energiser output without external intervention, reducing the need for complex manual control while improving energy efficiency through continuous optimization.
4Ease of manufacture
If mechanically operated switches are used to select output terminals, then ease of manufacture is improved, but labour intensity and convenience deteriorate
Solution Approach 1:
The patent replaces mechanical switching mechanisms with electronic or automated switching controlled by a controller. This substitution eliminates the need for manual mechanical operation while maintaining the ability to select different output terminals, significantly improving ease of operation without complicating the overall system through automated control.
