Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If camera-based bar code scanning is used in mobile devices, then device portability and networking capabilities are improved, but scanning speed and accuracy deteriorate

Engineering Contradiction:

Improvedevice portability and networking capabilitiesVSAvoidscanning speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The device is segmented into two functional parts: a dedicated optical scanner component for fast scanning and a mobile computing device for data processing and networking. This allows the optical scanning function to be optimized independently from the mobility features, resolving the contradiction between scanning speed and device portability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An optical scanner component serves as an intermediary between the mobile device and the bar code. This dedicated scanning component provides the speed and accuracy of traditional optical scanners while being integrated with mobile devices, thus maintaining both fast scanning and portability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If traditional optical scanners are used in clinical settings, then scanning speed is improved, but device ergonomics and ease of carrying deteriorate

Engineering Contradiction:

Improvescanning speedVSAvoiddevice ergonomics and ease of carrying

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The invention merges the optical scanner with a mobile computing device in a single integrated unit. This combination provides the scanning speed of traditional optical scanners while incorporating the ergonomic design, touchscreen interface, and portability of mobile devices, thus resolving the contradiction between scanning speed and ease of carrying.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device combines multiple functions including optical scanning, touchscreen display, data entry capabilities, and networking in a single unit. This multi-functionality allows the device to provide fast scanning while being as portable and easy to use as a mobile phone, resolving the ergonomics contradiction.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If expensive devices with keyboards are used, then data entry capability is improved, but device weight and ease of carrying deteriorate

Engineering Contradiction:

Improvedata entry capabilityVSAvoiddevice weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The invention replaces the mechanical keyboard with a touchscreen interface for data entry. This substitution eliminates the need for a heavy physical keyboard while maintaining full data entry capability through touch input, thus reducing device weight while preserving ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of manufacture

If camera-based scanning is used, then device cost is reduced, but scanning accuracy and speed deteriorate

Engineering Contradiction:

Improvedevice costVSAvoidscanning accuracy

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The device is segmented into a dedicated optical scanning component and a mobile computing component. This segmentation allows the use of a specialized, cost-effective optical scanner rather than an expensive integrated scanning system, while maintaining high scanning accuracy and speed through the dedicated scanning hardware.

Inventive Principle:

Principle #1Segmentation
