An adjustable wireless accessible point is designed with a base, multiple antenna modules, and driving modules that allow for synchronous movement and adjustment of antenna positions, inclinations, and orientations to customize the radiation pattern, including a rotatable, slidable, and inclining mechanism to optimize signal coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional wireless accessible points use fixed antenna configurations with limited radiation patterns, then the device structure remains simple and manufacturing is easy, but the adaptability to different field requirements and complex environments is insufficient

Engineering Contradiction:

Improveradiation pattern adaptabilityVSAvoidantenna adjustment mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transforming fixed antenna configurations into movable and adjustable ones. The antenna modules are designed to be movable relative to the base through mounting components that enable rotation and sliding, allowing the radiation pattern to be dynamically adjusted according to different field requirements rather than being static and limited

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the antenna system into multiple independent antenna modules, each with its own mounting component. This segmentation allows individual antennas to be adjusted independently or collectively, providing finer control over the radiation pattern while maintaining manageable system complexity through modular design

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple antennas with different radiation patterns are used to achieve pattern adjustment, then radiation pattern diversity is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improveradiation pattern diversityVSAvoidantenna module assembly ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent achieves radiation pattern diversity through a universal mounting component design that can accommodate multiple antenna modules with different radiation characteristics. The mounting component serves multiple functions: supporting the antenna body, enabling rotational movement, allowing sliding adjustment, and providing detachable installation. This multi-functional design simplifies manufacturing compared to creating entirely different antenna assemblies for each pattern requirement

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If antenna modules are made movable with rotatable and slidable mounting components, then radiation pattern adjustability is enhanced, but the device structure becomes more complex

Engineering Contradiction:

Improveradiation pattern adjustment easeVSAvoidmounting component structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple adjustment functions (rotation and sliding) into a single integrated mounting component. Rather than using separate mechanisms for each degree of freedom, the mounting component combines rotational joints and sliding guides into one unified structure that supports the antenna body while enabling both types of movement, thereby reducing overall structural complexity

Inventive Principle:

Principle #5Merging (Combining)

4Ease of repair

If detachable installation of antenna bodies on mounting components is implemented, then ease of repair and maintenance is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improveantenna module maintenance easeVSAvoiddetachable connection precision

Core Design Contradiction:

Ease of repairVSManufacturing precision

Solution Approach 1:

The patent incorporates preliminary action by designing the detachable connection interface with pre-aligned positioning features and guiding structures. The mounting component includes built-in alignment guides and positioning pins that automatically guide the antenna body into the correct position during attachment, ensuring precise alignment without requiring high-precision manual assembly or complex adjustment procedures during installation or repair

Inventive Principle:

Principle #10Preliminary action

AI summary

An adjustable wireless accessible point includes a base, a plurality of antenna modules and an antenna driving module. The plurality of antenna modules are movably disposed on the base and for emitting or receiving wireless signals. The antenna driving module is movably connected to the plurality of antenna modules and for driving the plurality of antenna modules to synchronously move relative to the base, so as to achieve a purpose of adjusting a radiation pattern of the adjustable wireless accessible point.
