Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional cartridge readers are used to read RFID and bar code data, then data retrieval is possible, but users must remove cartridges from cases which reduces convenience and efficiency

Engineering Contradiction:

Improveconvenience of data retrievalVSAvoidtime required to remove cartridge from case

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The cartridge reader is designed with multiple receiving areas to handle both cased and caseless cartridges, making it universally applicable to different cartridge states. This multi-functionality eliminates the need for users to remove cartridges from cases before scanning, as the reader can process both types directly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The housing is divided into distinct receiving areas: a first receiving area for cased cartridges and a second receiving area for caseless cartridges. This segmentation allows each area to be optimized for its specific cartridge type while maintaining the ability to read both RFID and bar code data from either configuration.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the cartridge reader has only one receiving area, then the device structure is simple, but it cannot accommodate both cased and caseless cartridges for proper positioning

Engineering Contradiction:

Improveability to accept cartridges with or without casesVSAvoidhousing structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing incorporates multiple receiving areas that provide universal acceptance for both cased and caseless cartridges. This design choice prioritizes adaptability over structural simplicity, allowing the same device to handle varying cartridge configurations without requiring separate readers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Different regions of the housing are designed with distinct characteristics: the first receiving area is configured to accommodate cased cartridges with appropriate spacing and access paths, while the second receiving area is designed for caseless cartridges. This local differentiation enables proper positioning and reading capabilities for each cartridge type.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the cartridge reader reads only RFID tags, then the device structure is simpler, but it cannot read bar code data which limits functionality

Engineering Contradiction:

Improvereading capabilityVSAvoidreader structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cartridge reader integrates both RFID reading capability and bar code scanning capability into a single device. The RFID reader and bar code reader are combined in one housing with shared receiving areas, allowing the device to read both types of data from cartridges regardless of whether they are in cases or not.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The reader is designed with multi-functionality to handle both RFID tags and bar codes, making it adaptable to different data storage formats on cartridges. This universal reading capability ensures that whether a cartridge has an RFID tag, bar code, or both, the reader can retrieve the necessary information.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables seamless data retrieval from RFID tags and bar codes on data cartridges whether they are in or out of their cases, enhancing user convenience and operational efficiency.

Implementation Method 1

A data cartridge may include an RFID cartridge memory (CM) chip... LTO drives typically include an RFID interface that enables the drive to read and/or write data to the CM chip of an LTO cartridge. LTO drives include a radio frequency interface to read and write data to the CM chip over radio frequency signals.

Methodology Applied

Scientific EffectRadio frequency identification (RFID): Electromagnetic Induction

Implementation Method 2

a bar code unit that reads bar code data from a bar code of the data cartridge

Methodology Applied

Scientific EffectLight reflection: Reflection

AI summary

A cartridge reader device includes an RFID unit that reads cartridge memory (CM) data from an RFID tag of a data cartridge, a bar code unit that reads a bar code of the data cartridge, and a housing that encloses the RFID unit and the bar code unit. The housing encloses the RFID unit and the bar code unit and defines at least one receiving area configured to accept the data cartridge and enables the bar code unit to read the bar code data from the bar code of the data cartridge. The reader device further includes a pair of mirrors positioned within the housing that direct light emitted by the bar code reader to the bar code of the data cartridge along a u-shaped path.
