Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive patches or conductive adhesive gel are used to attach electrodes, then electrodes can be non-invasively attached to the skin, but the attachment stability and vacuum seal reliability deteriorate leading to noise and signal interference
Solution Approach 1:
The patent applies vacuum suction technology to create a negative pressure environment within the detection device housing, forming a reliable vacuum seal between the housing and skin surface. This pneumatic attachment method replaces traditional adhesive patches and conductive gels, providing stable electrode contact without the reliability issues of adhesive-based solutions. The vacuum seal ensures consistent signal quality while maintaining non-invasive attachment.
2Ease of operation
If adhesive patches are used to attach electrodes, then non-invasive attachment is achieved, but measurement precision deteriorates due to noise and signal interference
Solution Approach 1:
The vacuum suction mechanism creates a sealed environment that eliminates air gaps and improves electrode-skin contact quality. By maintaining negative pressure, the system ensures consistent electrical contact between electrodes and skin, reducing noise and signal interference. This leads to enhanced measurement precision for biopotential detection while preserving the non-invasive nature of the attachment method.
3Reliability
If invasive methods are used to attach electrodes, then attachment stability improves, but patient comfort and ease of operation deteriorate
Solution Approach 1:
The patent employs vacuum suction to achieve stable electrode attachment without invasive procedures. The negative pressure system creates a secure seal between the housing and skin surface, maintaining reliable electrical contact equivalent to or better than invasive methods. Meanwhile, the non-invasive nature of vacuum attachment preserves patient comfort and simplifies the attachment process, eliminating the need for surgical intervention or painful procedures.
4Device complexity
If traditional adhesive methods are used, then device complexity remains low, but attachment reliability and signal quality worsen
Solution Approach 1:
The vacuum suction system integrates a vacuum source, sealing chamber, and control mechanism to create a reliable attachment system. While this increases device complexity compared to simple adhesive patches, the pneumatic seal provides superior attachment reliability and signal quality. The vacuum mechanism maintains consistent contact pressure and eliminates air gaps, ensuring stable biopotential detection throughout the monitoring period.
