Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the attachment sheet is expanded to broaden the range of detecting biological signals, then the detection range is improved, but the electrode connecting patterns break easily due to excessive local deformation
Solution Approach 1:
The attachment sheet is divided into a flexible electrode pad portion and a separate storage case portion. The electrode connecting patterns are confined to the electrode pad portion, which can deform independently without affecting the storage case or causing pattern breakage, thus maintaining both expanded detection area and pattern reliability.
Solution Approach 2:
The electrode pad portion uses a flexible attachment sheet that can stretch and deform to follow body movements. This flexibility allows the expanded detection area to move with the body without causing excessive deformation that would break the electrode connecting patterns, as the flexible material absorbs the mechanical stress.
2Area of moving object
If the attachment sheet is expanded to broaden the range of detecting biological signals, then the detection range is improved, but the biomedical electrode pad comes easily off the skin due to restricted stretching and contracting
Solution Approach 1:
The device is segmented into a flexible electrode pad portion for detection and a rigid storage case portion for housing electronics. The electrode pad can stretch and contract freely to follow body movements while maintaining skin contact, without being constrained by the storage case, thus improving both detection range and attachment stability.
Solution Approach 2:
The electrode pad portion is designed to be dynamically flexible, allowing it to stretch and contract as the body moves. This dynamic adaptation enables the expanded detection area to maintain stable attachment to the skin throughout body movements, preventing easy detachment while preserving the broader detection range.
3Ease of operation
If the portable case is worn around the arm by a belt to perform Holter electrocardiography, then the device can be worn on the body, but the biomedical electrode pad comes easily off the skin due to tensile force applied to the leads
Solution Approach 1:
The storage case is merged with the attachment sheet to form an integrated wearable device. The electrode pad portion remains firmly attached to the storage case, creating a unified structure where the leads are internally routed and protected. This integration eliminates the external lead connections that were subject to tensile forces, maintaining both wearability and attachment stability.
Solution Approach 2:
The integrated design uses the flexible attachment sheet to connect the electrode pad to the storage case, creating a unified wearable unit. This flexible connection allows the device to move with the body without creating tensile stress on external leads, preventing electrode pad detachment while maintaining comfort and ease of operation.
4Device complexity
If the case body is arranged on the front surface side of the attachment sheet, then the structure is simplified, but the skin contact and ventilation may be affected
Solution Approach 1:
The device is segmented into distinct functional portions: the electrode pad portion for skin contact and signal detection, and the storage case portion for housing electronics. This segmentation allows the electrode pad to maintain direct skin contact for optimal signal detection while the storage case is positioned separately, simplifying the overall structure without compromising skin contact comfort or ventilation.
