Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the energiser output voltage is increased to compensate for fence losses, then the effective fence voltage is improved, but energy losses increase exponentially and safety risks increase

Engineering Contradiction:

Improvefence voltage effectivenessVSAvoidenergy losses

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system dynamically changes the operating parameters (voltage, pulse width, energy) of the energiser based on real-time measurements of fence conditions. By adjusting these parameters according to actual losses rather than using fixed high voltage, the system maintains effective fence voltage while minimizing energy consumption and avoiding exponential energy losses.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system implements a feedback mechanism where energy losses are measured in real-time and this information is used to adjust the energiser output. The controller receives feedback about actual fence conditions and modifies the output parameters accordingly, creating a closed-loop control system that optimizes energy usage while maintaining effectiveness.

Inventive Principle:

Principle #23Feedback

2Loss of energy

If real-time measurement and response is implemented to reduce energy losses, then energy efficiency is improved, but device complexity increases

Engineering Contradiction:

Improveenergy lossesVSAvoidsystem complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The system performs self-diagnosis and self-adjustment by automatically measuring its own energy losses and correcting them without external intervention. The energiser monitors its own performance and the fence conditions, then autonomously adjusts its output parameters to optimize efficiency, eliminating the need for complex external control systems.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces mechanical voltage regulation methods with electronic measurement and control. Instead of using mechanical switches or manual adjustment mechanisms, the patent employs electronic sensors and digital controllers to measure energy losses and adjust output parameters, significantly reducing mechanical complexity while enabling real-time response.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a single output is switched to different wires using mechanically operated switches, then different fence sections can be energised, but labour intensity increases and convenience decreases

Engineering Contradiction:

Improvefence section selectionVSAvoidoperation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system replaces mechanical switching with electronic switching controlled by a microprocessor. The controller can electronically select and energize different fence sections without requiring physical switch manipulation. This substitution eliminates manual labour while maintaining the ability to selectively energize different wires or sections of the fence.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system automatically determines which fence sections require energizing based on real-time loss measurements, eliminating the need for manual selection. The controller autonomously manages the switching and energization of different fence sections based on detected conditions, making the system self-managing and highly convenient.

Inventive Principle:

Principle #25Self-service
