Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional biosensor inserters are used, then reliable biosensor insertion is achieved, but device size and material usage increase significantly

Engineering Contradiction:

Improvebiosensor insertion reliabilityVSAvoidinserter footprint

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The wearable device is folded into a recess of the biosensor inserter, with the secondary portion containing the transmitter unit nested within the inserter structure. This nesting arrangement reduces the overall footprint and material usage while maintaining insertion functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wearable device is designed to be foldable, transitioning from an extended configuration during insertion to a compact folded state within the inserter. This dynamic transformation reduces the inserter's required size and material consumption.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If conventional biosensor inserters are used, then insertion function is maintained, but manufacturing cost increases

Engineering Contradiction:

Improveinsertion functionVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

By nesting the wearable device within the inserter's recess and utilizing the foldable design, the overall device size is reduced, requiring fewer materials and reducing manufacturing costs while preserving the insertion function.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wearable device incorporates flexible, foldable components that can be compacted into the inserter, reducing material usage and manufacturing complexity while maintaining operational functionality.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation
