Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional complex devices for portable electronic devices face challenges in achieving both high electrostatic response speed and effective communication functions due to the same dielectric sheet layer being used for suppressors and capacitors, which compromises either the protection or communication functions.
Innovation Solution
A complex device is designed with a suppressor and capacitor made of different materials, where the suppressor has a higher dielectric constant than the capacitor, and they are stacked in a green sheet state and co-fired, allowing for improved electrostatic response speed while maintaining communication characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the suppressor and capacitor are made of the same dielectric sheet layer, then the manufacturing process is simplified, but the electrostatic response speed and communication function cannot both be optimized
Solution Approach 1:
The patent divides the complex device into two distinct functional modules: a suppressor portion with high dielectric constant material for electrostatic protection, and a capacitor portion with low dielectric constant material for communication functions. This segmentation allows each portion to be optimized independently with appropriate materials while maintaining a unified structure.
Solution Approach 2:
Different dielectric sheet layers are used in different regions of the complex device. The suppressor portion uses a first dielectric sheet layer with high dielectric constant (first dielectric constant) to achieve fast electrostatic response, while the capacitor portion uses a second dielectric sheet layer with low dielectric constant (second dielectric constant) to maintain communication characteristics. This local differentiation of material properties resolves the contradiction between manufacturing simplicity and functional performance.
2Speed
If the suppressor has high dielectric constant material, then the electrostatic response speed is improved, but the communication function may be compromised
Solution Approach 1:
The device is segmented into suppressor and capacitor portions with different dielectric materials. The suppressor portion uses high dielectric constant material for fast electrostatic response, while the capacitor portion uses low dielectric constant material for stable communication performance, eliminating the trade-off between speed and communication reliability.
Solution Approach 2:
High dielectric constant material is localized to the suppressor portion where fast response is needed, while low dielectric constant material is used in the capacitor portion where communication stability is required. This spatial differentiation of material properties allows both requirements to be satisfied simultaneously.
3Reliability
If the capacitor has low dielectric constant material, then the communication function is maintained, but the electrostatic protection capability is reduced
Solution Approach 1:
The complex device is divided into functional segments where the suppressor portion (with high dielectric constant) handles electrostatic protection and the capacitor portion (with low dielectric constant) handles communication functions. This segmentation ensures that low dielectric constant material does not compromise overall electrostatic protection capability.
Solution Approach 2:
Low dielectric constant material is confined to the capacitor portion where communication stability is needed, while high dielectric constant material is used in the suppressor portion for electrostatic protection. This localized material assignment prevents communication material from reducing protection capability.
4Reliability
If different dielectric sheet layers are used for suppressor and capacitor, then both electrostatic response speed and communication function are optimized, but the device complexity increases
Solution Approach 1:
The suppressor and capacitor are merged into a single integrated complex device with unified external terminals and coordinated internal structure. Different dielectric sheet layers are combined in a systematic arrangement where the first dielectric sheet layer (high dielectric constant) and second dielectric sheet layer (low dielectric constant) work together, reducing overall system complexity despite material differentiation.
Solution Approach 2:
The complex device achieves multi-functionality by integrating both suppressor and capacitor functions in a single structure. The different dielectric sheet layers are designed to work cooperatively, with the first dielectric sheet layer providing electrostatic protection and the second dielectric sheet layer providing communication capacitance, while sharing common external terminals and manufacturing processes.

This design enhances the electrostatic response speed and ensures reliable performance for both communication signal transmission and static electricity protection, simplifying manufacturing and reducing costs, thereby improving product competitiveness.
Implementation Method 1
the dielectric constant and the insulation resistance of the dielectric sheet layer constituting the suppressor and the capacitor, and the electrode structure of the suppressor affect the electrostatic response speed
Implementation Method 2
when the dielectric constant of the suppressor is greater than the dielectric constant of the capacitor by a certain ratio or more, the electrostatic response speed by the suppressor is rapidly improved while maintaining the communication characteristics in the wireless communication band
