Solution Overview

Problem

Conventional continuous glucose monitoring systems face issues with hypersensitivity and allergic reactions due to intrusive biosensors, requiring frequent replacement and risking damage to the transmitter during installation.

Innovation Solution

A physiological signal monitoring device with a base, biosensor, and transmitter featuring alignment structures that prevent collision during assembly, allowing for safe and secure attachment to prevent damage and allergic reactions, enabling the transmitter to be reused and reducing biosensor replacement frequency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the transmitter is moved directly into position during assembly, then the assembly process is simple and fast, but the connection part and signal output section collide causing damage to the biosensor

Engineering Contradiction:

Improveassembly speedVSAvoidbiosensor integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The alignment structures (alignment grooves and alignment protrusions) are pre-configured on the base and transmitter respectively, enabling automatic alignment during the assembly process. This preliminary structural arrangement guides the transmitter to approach the base in the correct orientation, preventing collision between the connection part and signal output section while maintaining assembly efficiency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The alignment structures act as intermediary elements between the transmitter and base, mediating their relative positioning. The alignment grooves and protrusions engage first to establish proper alignment, then the connection part and signal output section can safely connect without direct collision, thus protecting the biosensor while enabling assembly

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the biosensor is replaced frequently due to allergic reactions, then the skin hypersensitivity issue is addressed, but the transmitter is damaged during disengagement and reassembly

Engineering Contradiction:

Improveallergic reaction frequencyVSAvoidtransmitter durability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The alignment structures are pre-configured to guide the transmitter's approach to the base, ensuring that even during repeated assembly and disassembly operations, the connection part and signal output section align properly without collision. This preliminary structural arrangement protects the transmitter from damage during frequent biosensor replacements

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The alignment grooves and protrusions create a cushioning effect by establishing a controlled engagement sequence. The alignment features engage first, absorbing the mechanical stress of assembly, which prevents direct impact between the connection part and signal output section, thus protecting the transmitter during repeated assembly operations

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A physiological signal monitoring device includes a base, a biosensor and a transmitter. The biosensor includes a sensing section. The transmitter includes a connection part. The connection part and the signal output section cooperatively form a connection portion after the transmitter moving from an initial position to an assembled position. A safety gap is formed between the transmitter and the biosensor. When the transmitter moves from the initial position toward the assembled position, the safety gap serves to prevent at least one of the connection part of the transmitter and the signal output section of the biosensor from collision.
