Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If intelligent metasurface is designed for single-user beam manipulation, then beam manipulation capability is achieved, but signal enhancement and interference suppression in multi-user scenarios cannot be effectively realized

Engineering Contradiction:

Improvemulti-user scenario capabilityVSAvoidsignal enhancement and interference suppression performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the beam manipulation task by introducing separate manipulation parameters for different user groups (first user group and second user group). The metasurface divides users into multiple groups and applies different manipulation strategies to each group, enabling independent optimization of signal enhancement for intended users and interference suppression for neighboring cell users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic adaptability by allowing the metasurface to dynamically adjust manipulation parameters based on channel information and beam manipulation information. The system can adaptively optimize parameters for different user groups in real-time, transforming the static single-user design into a dynamic multi-user system that responds to changing communication conditions.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If beam manipulation is optimized for single-user scenario, then manipulation precision is achieved, but multi-user signal enhancement and interference suppression are compromised

Engineering Contradiction:

Improvebeam manipulation precisionVSAvoidmulti-user service capability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by optimizing manipulation parameters specifically for different user groups rather than using a uniform approach. Each user group receives tailored manipulation parameters that are optimized for their specific channel conditions and beam requirements, allowing precise beam manipulation for each group while maintaining overall multi-user capability.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent makes the metasurface universal by enabling it to serve multiple user groups simultaneously with different manipulation strategies. The system maintains the precise beam manipulation capability for each individual user group while also providing multi-user service capability, making the metasurface adaptable to various user scenarios without sacrificing precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If intelligent metasurface serves multiple terminal users simultaneously, then multi-user coverage is improved, but interference between users increases

Engineering Contradiction:

Improvemulti-user service capacityVSAvoidinterference between users

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful interference between users into a beneficial outcome by using the same metasurface to simultaneously enhance signals for intended users and suppress interference for neighboring cell users. The manipulation parameters are designed to direct beams toward intended users while creating nulls or reduced gain in directions of neighboring cell users, thus converting the potential interference problem into a solution that serves multiple users effectively.
