Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If internal signal phase adjustments are used to adjust coverage area, then coverage area can be adjusted, but signal strength is degraded and interference is increased

Engineering Contradiction:

Improvecoverage area adjustmentVSAvoidsignal strength

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces the mechanical/physical antenna orientation adjustment system with an electrical signal phase adjustment system. By using phase shifters to electronically adjust the signal phase, the system can change coverage area without physically moving the antenna, thereby avoiding the degradation of signal strength and increase of interference that would result from mechanical repositioning.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operating parameters of the antenna system by adjusting the signal phase rather than the physical position. By modifying the phase parameter of the transmitted signal, the coverage area can be adjusted while maintaining the antenna's fixed physical position, thus preserving signal strength and reducing interference.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If manual adjustment of antenna orientation is performed, then precise orientation control is achieved, but labor cost and safety risk increase

Engineering Contradiction:

Improveantenna orientation precisionVSAvoidadjustment cost and safety

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent replaces manual mechanical adjustment operations with an automated electrical control system. The phase shifters are controlled electronically to achieve precise antenna orientation without requiring personnel to physically climb towers or manually reposition antennas, thereby eliminating safety risks and reducing labor costs while maintaining precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-adjustment of antenna orientation through automated phase control. The electronic control system can automatically adjust the signal phase to achieve the desired coverage area without human intervention, making the adjustment process safer and more cost-effective while maintaining precision.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If repeated manual adjustments are made to accommodate environmental changes, then service coverage can be optimized, but maintenance cost and safety risk increase

Engineering Contradiction:

Improveservice coverage optimizationVSAvoidmaintenance time and cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces repeated manual adjustment operations with automated electrical phase control. When environmental changes require optimization of service coverage, the system can electronically adjust the signal phase through phase shifters without requiring maintenance teams to climb towers, thereby reducing maintenance time and cost while maintaining adaptability to environmental changes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electronic phase adjustment system allows for continuous and frequent adjustments of service coverage without the interruptions and costs associated with manual interventions. The system can continuously optimize coverage in response to environmental changes, eliminating the need for repeated maintenance visits and associated safety risks.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A remotely controllable antenna mount for use with a wireless telecommunication antenna provides both mechanical azimuth and mechanical tilt adjustment using AISG compatible motor control units and AISG control and monitoring systems to remotely adjust the physical orientation of the antenna. The mount control units are serially interconnected with existing AISG antenna control units (ACU's) which adjust internal electronic tilt of the antenna. The present solution provides the ability to both physically aim the antenna to adjust coverage area and also adjust the signal phase to fine tune the quality of the signal.
