Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous electrodes and wires are used for EEG measurement, then measurement accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The invention divides the EEG measurement system into modular components: multiple electrode assemblies are distributed across the scalp cap, each independently connected to circuit boards that process signals locally before transmission. This segmentation allows accurate multi-point measurement while reducing overall system complexity through distributed architecture.
Solution Approach 2:
The invention transitions from traditional wire-based signal transmission to wireless transmission in the third dimension. Circuit boards in the cap communicate with external devices via wireless communication modules, eliminating the need for extensive physical wiring while maintaining signal integrity and measurement accuracy.
2Measurement precision
If numerous electrodes and wires are attached to the body, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The invention merges multiple functional components into an integrated cap structure. Electrodes, circuit boards, wireless communication modules, and power management components are all combined within a single wearable cap, eliminating the need for separate wire connections and external equipment, thereby greatly improving wearing convenience while maintaining measurement precision.
Solution Approach 2:
The cap is designed to be self-contained with integrated power management and signal processing capabilities. The wireless communication module automatically transmits data without requiring manual wire connections, and the system manages its own power and signal routing, reducing the operational burden on the user.
3Reliability
If wires are used for signal transmission, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The invention replaces the mechanical wire-based signal transmission system with an electromagnetic wireless communication system. Circuit boards in the cap use wireless communication modules to transmit EEG data to external devices, eliminating physical constraints while maintaining reliable data transmission through established wireless protocols.
4Measurement precision
If multiple electrodes are used, then measurement precision is improved, but device complexity deteriorates
Solution Approach 1:
The invention segments the signal processing function by placing individual circuit boards near each electrode or electrode group within the cap. Each circuit board independently processes signals from its associated electrodes before transmission, reducing the complexity of managing multiple electrodes and wires by distributing processing tasks across multiple independent modules.

AI summary
The present invention provides an electroencephalogram measurement structure formed by an ear-hanging structure and a second circuit board. The ear-hanging structure includes a body. An ear-hanging member is disposed at the extension of the body. The body can be worn on the ear via the ear-hanging member. In addition, a first reference electrode and a second reference electrode are disposed on the body and coupled to a first circuit board. The first circuit board is coupled to an electrical jack; the second circuit board is coupled to the electrical jack via an electrical plug. Thereby, the electroencephalogram measurement can be performed simply by wearing the ear-hanging member on the ear of the person under test. Hence, the problems of complicated wiring and inconvenience in wearing can be solved concurrently.
