Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed antenna structure is used, then the device complexity is reduced, but the adaptability to different frequency bands is worsened

Engineering Contradiction:
Improveadaptability to different frequency bandsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a mechanically adjustable antenna structure where the radiating element can be repositioned along the ground wall by changing the configuration of connecting elements. This dynamic adjustment capability allows the antenna to adapt its electrical characteristics for different frequency bands, resolving the contradiction between fixed structure simplicity and frequency adaptability requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters of the antenna structure, specifically the position of the radiating element relative to the ground plane, by adjusting the connecting elements. This parameter change enables the antenna to optimize its performance for different frequency bands without requiring multiple fixed antenna structures, thus improving adaptability while controlling device complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple antenna structures are used for different frequency bands, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvemulti-broadband capabilityVSAvoidmechanical structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs a single antenna structure that can serve multiple frequency bands by allowing adjustment of the radiating element's position. The same physical structure performs different functions for different frequency ranges, eliminating the need for multiple dedicated antenna structures and thereby reducing overall device complexity while maintaining multi-broadband capability.

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

Solution Approach 2:

The patent segments the connecting elements into adjustable components that can be reconfigured independently. This segmentation allows flexible adjustment of the radiating element's position to optimize performance across different frequency bands, enabling multi-functionality from a single unified structure rather than requiring multiple complete antenna systems.

Inventive Principle:
Principle #1Segmentation

3Power

If the antenna gain is increased for all frequency bands, then the transmission rate is improved, but the interference between concurrent transmissions increases

Engineering Contradiction:
Improveantenna gainVSAvoidinterference between RF signals
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The patent enables local optimization of antenna gain by allowing independent adjustment of the radiating element's position for different frequency bands. This local quality adjustment ensures that high gain is achieved only at the specific frequency band where it is needed, rather than uniformly across all bands, thereby improving transmission rate at the target frequency while minimizing interference to other concurrent transmissions.

Inventive Principle:
Principle #3Local quality
