Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric fence energizers face challenges in efficiently managing output voltage, particularly in reducing energy losses and maintaining safety, as they often require human intervention and fail to adapt to non-linear energy losses along the fence, leading to increased voltage that can be lethal and inefficient.
Innovation Solution
A selective fence energizer system that varies the energy or waveshape of each pulse based on measured energy losses, using bipolar pulses and a controller to adjust the fence operating voltage, allowing for real-time energy adjustments and minimizing losses by selectively energizing strands or sections of the fence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the output voltage of the energiser is increased to compensate for energy losses on the fence, then the effective output energy is improved, but the safety risks to humans and animals increase
Solution Approach 1:
The energiser dynamically adjusts its output voltage based on real-time feedback from energy loss measurements. The controller continuously monitors fence conditions and modulates the output voltage accordingly, transitioning from static to dynamic operation to optimize energy delivery while maintaining safety thresholds.
Solution Approach 2:
The system implements a feedback mechanism where energy loss measurements from the fence are fed back to the controller, which then adjusts the energiser output. This closed-loop control enables the system to respond to actual fence conditions rather than operating at fixed voltage levels.
2Ease of operation
If a mechanically operated switch is used to select output energy levels, then the ease of operation is improved, but the labour intensity and convenience deteriorate
Solution Approach 1:
The energiser system performs self-adjustment of output voltage based on automatic energy loss measurements. The controller autonomously determines the appropriate voltage level without requiring human intervention, making the system self-regulating and eliminating manual switching operations.
Solution Approach 2:
The patent replaces mechanical switching systems with an electronically controlled voltage regulation system. Instead of using physical switches to select voltage levels, the system uses electronic control circuits to dynamically adjust the output voltage based on measured energy losses.
3Reliability
If the fence voltage is maintained at a high set point to ensure adequate voltage levels, then the reliability is improved, but the energy losses increase exponentially
Solution Approach 1:
The system transitions from maintaining a fixed high voltage set point to dynamically adjusting voltage based on actual fence conditions. The controller modulates the output voltage in real-time, allowing the system to operate at the minimum necessary voltage level while still ensuring adequate fencing performance.
Solution Approach 2:
The patent changes the operating parameter from a fixed voltage set point to a variable voltage level determined by energy loss measurements. This parameter change enables the system to optimize the balance between reliability and energy efficiency by adjusting voltage according to actual fence conditions.
4Power
If the energiser output is increased to compensate for arcing losses at a single point, then the effective energy delivery is improved, but the safety risks and overall energy waste increase
Solution Approach 1:
The system applies local quality control by measuring and compensating for energy losses at specific locations along the fence. Rather than uniformly increasing voltage across the entire fence, the controller adjusts output based on localized loss measurements, enabling targeted compensation for arcing or loading issues at specific points.
Solution Approach 2:
The patent implements feedback control where energy loss measurements from the fence are continuously monitored and used to adjust the energiser output. This feedback mechanism enables the system to respond to localized issues such as arcing at specific fence points without unnecessarily increasing overall voltage and energy consumption.
