Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antenna designs are used, then electromagnetic wave reception and emission can be achieved, but the device size becomes large and efficiency is insufficient
Solution Approach 1:
The patent changes the electromagnetic parameters by introducing a dielectric medium with specific permittivity and conductor elements with specific inductance and capacitance values. This creates resonant conditions that enhance electromagnetic wave interaction efficiency while maintaining a compact form factor, resolving the contradiction between efficiency and device size.
Solution Approach 2:
The patent employs electromagnetic resonance through tuned conductor elements that oscillate at specific frequencies. This resonant vibration mechanism enhances the coupling between the antenna elements and electromagnetic waves, improving reception and emission efficiency without requiring larger dimensions.
2Adaptability or versatility
If multiple antenna elements are added to handle multiple signals, then signal versatility improves, but device complexity increases
Solution Approach 1:
The patent creates antenna elements that can simultaneously handle multiple electromagnetic signals through the use of conductor elements forming electric loops with specific resonance frequencies. These elements serve multiple functions by being able to receive and emit different signals across various frequencies, reducing the need for separate dedicated antennas for each signal type.
Solution Approach 2:
The patent combines multiple antenna functions into a unified structure where conductor elements form integrated electric loops within the dielectric medium. This merging approach allows multiple signals to be processed through a consolidated antenna system rather than requiring separate independent antenna elements for each signal.
3Ease of manufacture
If conventional manufacturing methods are used, then device production is possible, but cost-effectiveness and ease of manufacture are reduced
Solution Approach 1:
The patent replaces complex mechanical antenna structures with planar conductor elements printed on or within a dielectric substrate. This substitution enables the use of standard PCB manufacturing techniques instead of traditional mechanical fabrication methods, significantly reducing production costs and improving ease of manufacture while maintaining electromagnetic performance.
Solution Approach 2:
The patent optimizes the geometric parameters of conductor elements (length, width, spacing) and dielectric properties to achieve desired resonance frequencies and impedance characteristics. These parameter optimizations allow the antenna to meet performance requirements using standard manufacturing tolerances and materials, making the design both high-performance and cost-effective to produce.
