Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If omnidirectional antenna is used, then signal coverage is improved, but transmission distance is reduced
Solution Approach 1:
The antenna is divided into multiple independent radiating elements (first radiating element, second radiating element, third radiating element, fourth radiating element) arranged in a specific geometry. Each element contributes to the overall radiation pattern, enabling the antenna to achieve both omnidirectional coverage and extended transmission distance through constructive interference of electromagnetic waves from multiple sources.
Solution Approach 2:
The antenna transitions from a planar two-dimensional arrangement to a three-dimensional tetrahedral structure. The radiating elements are positioned at vertices of a tetrahedron, utilizing spatial dimensionality to create a radiation pattern that maintains omnidirectional coverage while extending the effective transmission distance through three-dimensional electromagnetic field distribution.
2Length of stationary object
If antenna gain is increased, then transmission distance is extended, but device complexity is increased
Solution Approach 1:
Multiple radiating elements are merged into a single integrated antenna structure with a unified feeding system. The first, second, third, and fourth radiating elements are electrically connected to a common feed point, allowing the antenna to achieve high gain through element combination while maintaining relatively simple device complexity compared to multiple separate antenna systems.
Solution Approach 2:
The antenna structure serves multiple functions simultaneously: it provides omnidirectional signal coverage, extends transmission distance through high gain, and maintains broad frequency bandwidth. The same tetrahedral element configuration achieves all three objectives without requiring additional components or complex subsystems.
