Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If multiple reagent containers with radio IC tags are arranged in a reagent container holding part with corresponding antenna parts, then reagent information management is enabled, but erroneous reading and writing of information may occur due to radio wave interference between adjacent containers

Engineering Contradiction:

Improveautomatic reagent information managementVSAvoidaccuracy of information reading and writing

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The reagent container holding part is divided into multiple independent regions, each with its own antenna part and radio wave blocking parts. The radio wave blocking parts segment the radio wave fields to prevent interference between adjacent reagent containers, allowing each antenna to communicate only with its corresponding reagent container's radio IC tag.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Radio wave blocking parts are introduced as intermediary elements between adjacent antenna parts and reagent containers. These blocking parts act as mediators that selectively prevent radio waves from reaching non-target reagent containers while allowing communication between the antenna part and its corresponding reagent container.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If radio wave blocking parts are added to prevent erroneous communication, then information accuracy is improved, but device complexity increases

Engineering Contradiction:

Improveaccuracy of information reading and writingVSAvoidstructure of reagent container holding part

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The radio wave blocking parts are merged with the reagent container holding part structure itself, forming an integrated design. The blocking parts are positioned within the holding part to define separate regions for each reagent container, combining the holding function and radio wave blocking function into a single structural element.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The radio wave blocking parts serve multiple functions: they structurally support the arrangement of reagent containers, define the boundaries of communication regions, and actively block radio waves to prevent interference. This multi-functionality reduces the need for additional separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)
