Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the biosensor and transmitter are separately packaged and assembled right before use, then the device can be conveniently stored and transported, but static electricity accumulates during transport which damages the biosensor and internal electronic components

Engineering Contradiction:

Improveconvenience of storage and transportVSAvoidprotection against electrostatic discharge

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The electrostatic discharge protective unit is pre-installed on the transmitter before packaging and transport. This preliminary protective measure ensures that when the biosensor is later assembled with the transmitter, the biosensor is already protected from electrostatic discharge, eliminating the need for last-minute assembly while maintaining protection against static electricity damage during storage and transport

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The electrostatic discharge protective unit acts as an intermediary component between the biosensor and the transmitter's internal electronic components. It provides a dedicated protection mechanism that intercepts and dissipates static electricity before it can reach and damage the sensitive biosensor and circuit board components, thereby resolving the contradiction between ease of separate packaging and reliability during transport

Inventive Principle:

Principle #24Intermediary (Mediator)

2Volume of moving object

If the biosensor and transmitter are miniaturized, then the device becomes more compact and wearable, but the electrostatic-discharge issue becomes more serious affecting operation and lifespan

Engineering Contradiction:

Improvesize of biosensor and transmitterVSAvoidsusceptibility to electrostatic discharge

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The electrostatic discharge protective unit is strategically positioned at the connecting port where the biosensor interfaces with the transmitter. This localized protection focuses the anti-electrostatic function precisely where the biosensor is most vulnerable during assembly, allowing the overall device to remain miniaturized while providing targeted protection against electrostatic discharge at the critical interface point

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The protective unit serves as an intermediary shield between the external environment (source of static electricity) and the miniaturized biosensor components. By placing this protective barrier at the connection interface, the design enables miniaturization while compensating for the increased susceptibility to electrostatic damage that comes with smaller component sizes

Inventive Principle:

Principle #24Intermediary (Mediator)
