Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a conventional antenna structure is used, then the device complexity is low, but the antenna cannot be selectively deactivated to save power

Engineering Contradiction:
Improvepower consumptionVSAvoidantenna device complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The antenna system is divided into multiple independent antenna elements (first antenna, second antenna, third antenna, fourth antenna), each capable of being independently controlled and deactivated. This segmentation allows selective power consumption management by deactivating specific antenna elements based on communication requirements, thereby reducing overall power consumption while maintaining the ability to provide coverage when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The antenna device incorporates dynamic control mechanisms including switching elements and control circuitry that enable real-time activation and deactivation of antenna elements. The system can dynamically adjust which antennas are active based on traffic patterns, user distribution, and network conditions, allowing power consumption to be optimized without permanently sacrificing coverage capability.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If antenna elements are deactivated to save power, then power consumption is reduced, but the coverage area may be insufficient

Engineering Contradiction:
Improvepower consumptionVSAvoidcoverage area
Core Design Contradiction:
Use of energy by moving objectVSArea of stationary object

Solution Approach 1:

By segmenting the antenna system into multiple independent elements distributed across different locations and orientations, the system can selectively activate only the subset of antennas needed to provide adequate coverage for current traffic demands. This allows coverage area to be maintained dynamically rather than requiring all antennas to remain permanently active.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes operational parameters by adjusting which antenna elements are active based on real-time network conditions, user distribution, and traffic patterns. This dynamic parameter adjustment allows the coverage area to be optimized for current needs while reducing power consumption by keeping unnecessary antennas deactivated.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the antenna structure is simplified, then device complexity is reduced, but adaptability to different communication scenarios is limited

Engineering Contradiction:
Improvecommunication scenario adaptabilityVSAvoidantenna device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The antenna system is segmented into multiple independent elements that can be individually controlled, allowing the system to adapt to different communication scenarios by activating appropriate subsets of antennas. This segmentation provides versatility without requiring a completely complex reconfigurable structure, as each element operates independently with simple control logic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple antenna elements are designed with universal characteristics, where each antenna element can serve multiple functions and adapt to different communication scenarios. The control device intelligently selects and activates appropriate antennas based on the specific scenario, providing multi-functionality and adaptability while maintaining relatively simple individual antenna structures.

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