Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If barcode is used for data storage on reaction support unit, then data can be read, but data storage capacity is limited and readout is prone to malfunction

Engineering Contradiction:
Improvedata readout reliabilityVSAvoiddata storage capacity
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent replaces the barcode system with a digital camera-based imaging system that captures and stores digital images of the reaction support unit. This digital copy approach enables larger data quantities to be stored and read without the limitations of barcode technology, improving both storage capacity and readout reliability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent substitutes the optical barcode reading system with a digital camera-based imaging and processing system. This replacement allows for more robust data capture and processing, eliminating the malfunction-prone nature of barcode reading while enabling enhanced data storage capabilities through digital image processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If larger data quantities are stored on reaction support unit, then more information is available, but storage cost increases

Engineering Contradiction:
Improvedata storage capacityVSAvoiddata storage cost
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The patent uses digital image copying and processing to store and retrieve large quantities of data on the reaction support unit. By encoding data in digital images rather than using traditional storage media, the system achieves high-capacity storage at low cost, as digital cameras and processing software can handle large data sets without proportionally increasing manufacturing expenses.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transitions from linear barcode data storage to two-dimensional matrix code storage on the reaction support unit. This dimensional change dramatically increases the data storage capacity within the same physical space, allowing larger data quantities to be stored without increasing the size or cost of the storage medium.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
