Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal processing apparatus in mobile cellular devices require significant space due to the size of delay lines and other circuitry, making it challenging to reduce the overall device size.
Innovation Solution
A matrix with magnetically repelling magnetic particles is used to create a delay line, where the magnetic particles are distributed in a structured order within an elastic matrix, allowing them to move and propagate signals through magnetic repulsion, enabling a compact signal processing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional signal processing circuitry (delay lines, memories, correlators, filters) is used, then signal processing functions are achieved, but the device size becomes relatively large
Solution Approach 1:
The patent replaces traditional electronic/magnetic signal processing circuitry with a mechanical system consisting of magnetic particles embedded in an elastic matrix. The signal processing function is achieved through mechanical wave propagation through the particle matrix, substituting electronic components with a mechanical analog system that occupies significantly less space.
Solution Approach 2:
The patent changes the fundamental operating parameters by using mechanical wave speed through the magnetic particle matrix instead of electrical signal speed in traditional circuitry. By adjusting the elastic modulus of the matrix and the spacing of magnetic particles, the delay characteristics can be tuned to achieve sufficient signal processing with minimal device volume.
2Volume of moving object
If the volume required for signal processing apparatus is reduced, then device size decreases, but signal processing sufficiency may be compromised
Solution Approach 1:
The patent employs a composite material system where magnetic particles are distributed within an elastic matrix. This composite structure enables the system to achieve both compact volume and adequate signal processing performance by leveraging the unique properties of each material component - the magnetic particles for signal interaction and the elastic matrix for mechanical wave propagation.
