Solution Overview
Problem
Existing electronic entities with multiple connections face difficulties in connecting electronic components to microcircuits due to challenges in ensuring flatness during module insertion, particularly when using anisotropic adhesives, which are not suitable for thin components and printed circuits.
Innovation Solution
The integration of a double-antenna system for wireless radiofrequency powering, where a first antenna in the body is connected to a direct current source through an oscillator, and a second antenna in the module is connected to the electronic component through a rectifier circuit, enabling electromagnetic coupling and eliminating the need for physical connections between the module and the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anisotropic adhesive is used to connect the electronic component to the microcircuit, then the connection is achieved, but the flatness cannot be ensured and thick objects are required
Solution Approach 1:
The patent replaces the mechanical adhesive bonding system with an electromagnetic coupling system. The first antenna in the body and second antenna in the module create an electromagnetic field that couples the electronic component to the microcircuit without physical contact, eliminating the need for adhesives and associated flatness requirements.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the electronic component and microcircuit. The oscillating electromagnetic field generated by the first antenna couples energy and signals to the second antenna, serving as a non-contact mediator that replaces direct mechanical connections.
2Reliability
If many connections (10-20 terminals) are made between the electronic component and microcircuit, then the electronic component can be connected, but the connection difficulty increases during module insertion
Solution Approach 1:
The patent replaces the complex mechanical multi-terminal connection system with a single electromagnetic coupling interface. Instead of making 10-20 physical contacts during insertion, the system uses electromagnetic fields to transfer energy and signals, dramatically reducing connection complexity.
Solution Approach 2:
The patent merges multiple separate connection functions (power supply, data transmission, signaling) into a single electromagnetic coupling interface. The electromagnetic field simultaneously carries multiple types of information and energy between the module and body, consolidating what would otherwise require multiple physical connections.
3Ease of operation
If the electronic component is located on the surface of the entity, then it is accessible from outside, but connection to the microcircuit inside the body becomes difficult
Solution Approach 1:
The patent uses electromagnetic coupling to bridge the gap between the surface-mounted electronic component and the internal microcircuit. The electromagnetic field penetrates through the body material to establish communication without requiring physical contact or complex wiring through the component.
