Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If jumper wires of short length (1-2 m) are used to connect symmetrically arranged leaky coaxial cables, then the connection is simple and the initial field intensity is sufficient, but the tail end switching area becomes too long, switching becomes difficult, and the signal-to-noise ratio decreases

Engineering Contradiction:

Improveconnection simplicityVSAvoidsignal-to-noise ratio

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent divides the single long jumper wire into multiple shorter jumper wires arranged in series. Each jumper wire connects adjacent leaky coaxial cables, forming a segmented connection structure. This segmentation reduces the length of each individual jumper wire while maintaining overall connectivity, thereby improving signal-to-noise ratio and switching performance without compromising connection simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimensional connection (one long jumper wire) to a multi-dimensional arrangement (multiple jumper wires in series along the cable path). This dimensional change allows the connection to follow the actual layout of leaky coaxial cables more closely, reducing unnecessary wire length and improving signal quality

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Use of energy by moving object

If the coverage radius is designed with engineering margin, then the system has sufficient initial field intensity, but the tail end switching area becomes excessively long and switching cannot be performed normally

Engineering Contradiction:

Improveinitial field intensityVSAvoidswitching area length

Core Design Contradiction:

Use of energy by moving objectVSLength of stationary object

Solution Approach 1:

The patent applies different jumper wire configurations at different locations along the leaky coaxial cable system. Short jumper wires are used where cables are closely spaced, while the segmented arrangement adapts to local geometry. This local optimization ensures sufficient field intensity at the initial end while controlling switching area length at the tail end

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent creates a dynamic switching environment by using multiple short jumper wires that can be independently managed. This allows for more flexible and timely switching operations compared to a single long jumper wire, enabling the system to adapt to changing signal conditions along the cable length

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If identical grooving parameters are used for outer conductors of symmetrically arranged leaky coaxial cables, then the manufacturing is simple and consistent, but the field intensity distribution becomes uneven and MIMO effect is severely affected

Engineering Contradiction:

Improvemanufacturing consistencyVSAvoidMIMO effect

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces asymmetric grooving parameters for leaky coaxial cables at different positions along the transmission path. Cables closer to the initial end have different groove characteristics than those at the tail end. This asymmetric design creates more uniform field intensity distribution and enables effective MIMO operation while maintaining reasonable manufacturing complexity

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent systematically varies grooving parameters (such as groove depth, spacing, or pattern) along the length of the cable system. This parameter progression optimizes field intensity distribution to match the signal attenuation characteristics, ensuring consistent performance across different locations and enabling reliable MIMO functionality

Inventive Principle:

Principle #35Parameter changes
