Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in miniaturization due to the need for increased distance between the radio wave radiation source and the lens to enhance effective aperture area, leading to increased size and cost associated with higher lens processing accuracy.
Innovation Solution
A communication apparatus incorporating a first phase control plate positioned at a distance L1 from the radiation source, where the phase of the electromagnetic wave differs based on distance from a representative point, allowing power to be supplied up to a position separated by L1/2, thereby reducing the distance between the radiation source and the lens and achieving thinning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the distance between the radio wave radiation source and the lens is increased to increase the effective aperture area, then the directivity is improved, but the overall size of the communication apparatus is increased
Solution Approach 1:
The patent changes the optical parameters by introducing a phase control plate with specific phase distribution characteristics. The plate creates a phase difference corresponding to a focal length of L1/2, which modifies the wavefront propagation without requiring physical distance increase. This parameter transformation allows achieving the same effective aperture effect with reduced physical dimensions.
Solution Approach 2:
The phase control plate acts as an intermediary element between the radiation source and the lens. It mediates the electromagnetic wave propagation by introducing controlled phase shifts, enabling the system to achieve enhanced effective aperture area without increasing the physical distance between components. The plate transforms the direct spatial relationship into a phase-based control mechanism.
2Length of stationary object
If the lens thickness is reduced to miniaturize the communication apparatus, then the overall size is decreased, but the lens processing accuracy requirements are increased
Solution Approach 1:
The patent replaces the traditional mechanical lens focusing mechanism with a phase control plate that uses electromagnetic phase manipulation. Instead of relying on precise mechanical lens shaping and positioning, the system uses a phase distribution pattern on the plate to control wavefront propagation. This substitution reduces the need for high-precision mechanical lens processing while achieving the same focusing effect.
3Volume of moving object
If the distance between the radiation source and the lens is reduced to miniaturize the apparatus, then the overall size is decreased, but the effective aperture area is reduced
Solution Approach 1:
The patent transitions from controlling effective aperture area through one-dimensional spatial distance to controlling it through two-dimensional phase distribution on the phase control plate. By manipulating the phase across the plate surface, the system can achieve enhanced effective aperture area without increasing the physical distance between the radiation source and the lens, effectively adding a phase dimension to the control mechanism.
