Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual removal of snow and ice is used, then the reflector can be cleared, but user safety risks and inconvenience increase

Engineering Contradiction:
Improvesnow removal convenienceVSAvoiduser safety risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical manual removal system with an electrical heating system. Heating elements are embedded in the reflector surface and activated by a control circuit that detects snow/ice conditions, automatically melting the accumulation without requiring user physical intervention, thereby eliminating safety risks and inconvenience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The heating system operates autonomously by detecting snow or ice accumulation on the reflector and automatically activating the heating elements to melt the accumulation. The system serves itself by monitoring its own operational conditions and initiating the appropriate clearing action without external user input.

Inventive Principle:
Principle #25Self-service

2Extent of automation

If a heating system is implemented, then snow and ice can be removed automatically, but power supply complexity increases

Engineering Contradiction:
Improvesnow removal automationVSAvoidpower supply system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent utilizes the existing coaxial cable that already connects the satellite receiver to the dish for multiple purposes: signal transmission and power delivery. The heating system draws power through this existing infrastructure, eliminating the need for separate power cables or additional electrical infrastructure, thereby reducing overall system complexity despite adding automation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a power supply circuit as an intermediary component that converts the receiver's output voltage into appropriate heating elements voltage. This intermediary manages the power conversion and distribution, allowing the heating system to integrate seamlessly with the existing satellite receiver and coaxial cable infrastructure without requiring direct high-voltage connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If heating elements are activated continuously, then snow and ice are removed efficiently, but energy consumption increases

Engineering Contradiction:
Improvesnow removal efficiencyVSAvoidheating energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic or conditional heating activation based on snow/ice detection rather than continuous operation. The control circuit monitors the reflector surface conditions and activates heating elements only when accumulation is detected, thereby maintaining effective snow removal while significantly reducing overall energy consumption compared to continuous heating.

Inventive Principle:
Principle #19Periodic action

AI summary

Apparatus and systems are described herein for heating a satellite antenna reflector to remove snow and ice from the reflector surface. A satellite heating system includes a heating element attached to the satellite antenna reflector and a battery associated with the heating element. A satellite receiver provides a satellite antenna with a supply voltage over cabling communicatively coupling the satellite receiver and the satellite antenna. The supply voltage is further utilized to charge the battery. The heating element may then utilize the power supplied by the battery to heat the surface of the reflector, removing ice and snow from the reflector surface.
