Physiological Signal Monitor With Removable Transmitter Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional physiological signal monitoring devices suffer from hypersensitivity reactions due to intrusive biosensors, requiring frequent replacement, and have bulky or complex coupling mechanisms for transmitters, which are also expensive.
Innovation Solution
A physiological signal monitoring device with a base, biosensor, and transmitter featuring removable coupling structures and sealing mechanisms to prevent fluid leakage, allowing for easy detachment and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coupling lock mechanism is used to prevent easy disengagement of the transmitter, then the transmitter remains securely mounted, but the device thickness increases making it bulky
Solution Approach 1:
The coupling mechanism is divided into two separate structures: a first coupling structure on the base and a second coupling structure on the transmitter. These segmented coupling structures engage with each other through openings in the base, allowing secure mounting without requiring a thick coupling lock mechanism, thus reducing overall device thickness while maintaining reliability.
2Reliability
If a coupling mechanism with high minimum thickness is used, then the transmitter cannot easily disengage from the base, but the structure becomes too complicated to manufacture and operate
Solution Approach 1:
The coupling mechanism is segmented into simple first and second coupling structures that engage through openings. This segmentation simplifies the overall structure, making it easier to manufacture and operate compared to a single complex coupling lock mechanism, while still providing secure mounting.
Solution Approach 2:
The coupling engagement is extracted through openings in the base, allowing the first and second coupling structures to interact externally. This extraction simplifies the internal structure by eliminating the need for a complex internal coupling lock mechanism, reducing both manufacturing complexity and operational difficulty.
3Object-affected harmful factors
If the biosensor is replaced frequently due to hypersensitivity reactions, then the host's allergic reaction is managed, but the transmitter disengagement and reattachment process becomes time-consuming
Solution Approach 1:
The transmitter is separated from the base into distinct components with simple coupling structures. This segmentation allows the transmitter to be quickly detached and reattached when biosensor replacement is needed, reducing the time loss associated with frequent biosensor changes due to hypersensitivity reactions.
Solution Approach 2:
The coupling engagement is extracted through openings, allowing quick manual manipulation of the transmitter. This extraction enables rapid disengagement and reattachment of the transmitter during biosensor replacement, minimizing time loss while managing host hypersensitivity reactions.

AI summary
A physiological signal monitoring device includes a base (1) including a base body (11) that has a bottom plate (111) and an opening (117), a biosensor (2) mounted to the base (1), and a transmitter (3) removably mounted to the base body (11). The base (1) further includes a first coupling structure (12) disposed on the bottom plate (111), and the transmitter (3) includes a second coupling structure (37) coupled to the first coupling structure (12) when the transmitter (3) is mounted to the base body (11). When the first and second coupling structures (12, 37) are coupled to each other, they are disposed to be distal from a periphery cooperatively defined by the base (1) and the transmitter (3). They are uncoupled from each other when an external force is applied through the opening (117) of the base body (11) to separate the transmitter (3) from the base (1).
