Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bioimpedance measurement technologies face issues such as signal loss due to cable detachment during surgery, discomfort to patients, and noise interference from external signals, particularly when electrodes are placed on the dorsal region of the body.
Innovation Solution
A kit comprising disposable devices with non-conductive substrates, thin disposable connectors, and printed conducting lines that are adherable to the skin, reducing discomfort and noise interference by minimizing the thickness of connectors and using floating conducting lines for electrical shielding, along with an authentication tag for ensuring proper connection and replacing devices after a recommended usage period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrodes with thicker connectors are used, then connection reliability is improved, but patient comfort deteriorates due to pressure sores
Solution Approach 1:
The patent changes the thickness parameter of the connector from conventional dimensions to less than 4mm, fundamentally altering the physical dimension to reduce pressure on the patient's skin while maintaining adequate electrical connection reliability for bioimpedance measurements
2Measurement precision
If electrodes are placed on the dorsal region for signal measurement, then measurement capability is improved, but noise interference from external signals worsens
Solution Approach 1:
The patent introduces floating conducting lines as intermediary shielding elements between the signal-carrying conducting lines and the external environment. These floating lines act as a protective mediator that blocks external noise interference while allowing the dorsal placement configuration to maintain its signal measurement capability
3Device complexity
If conducting lines are exposed without shielding, then device complexity is reduced, but signal integrity deteriorates due to cross-talk
Solution Approach 1:
The patent introduces floating conducting lines as intermediary shielding elements between the signal-carrying conducting lines. These floating lines act as a protective mediator that blocks external noise interference while allowing the dorsal placement configuration to maintain its signal measurement capability
Solution Approach 2:
The patent uses thin conducting lines printed on the substrate to provide electrical shielding. The conducting lines are arranged in a layered configuration where floating lines shield the signal lines, creating a protective structure that maintains signal integrity without adding substantial thickness or complexity

AI summary
A kit for transmitting and sensing signals comprises: a multi-connection cable having a plurality of cable connectors at a distal end of the cable for establishing electrical communication between each of the cable connectors and a system for measuring bioimpedance that is connectable to a proximal end of the cable, and a plurality of devices for transmitting and sensing signals. Each device comprises a non-conductive substrate adherable to a skin of a subject, a first and a second electrical contacts printed on the substrate, and a disposable connector. Each disposable connector is connectable to a compatible cable connector of the cable in a manner that a combined thickness of the disposable connector and the compatible cable connector, once connected, is less than 4 mm.
