Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid battery holders or metal tabs are used to couple batteries to circuit boards, then electrical connection is ensured, but label thickness increases and printer feeding becomes difficult

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidlabel thickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent uses a flexible printed circuit board (FPC) to replace rigid battery holders and metal tabs. The FPC is folded back and adhered to the battery, creating a flexible electrical connection that maintains reliability while eliminating rigid structures that increase thickness and interfere with printer feeding.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent replaces the mechanical rigid connection system (battery holders and metal tabs) with an adhesive-based flexible connection system. The adhesive layer bonds the FPC to the battery, providing electrical connection without the mechanical rigidity that causes thickness issues.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If electronic tracking labels with sensors and multiple communication interfaces are implemented, then tracking functionality is improved, but device complexity increases

Engineering Contradiction:

Improvetracking functionalityVSAvoidlabel complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple communication interfaces (Bluetooth, Wi-Fi, cellular) and various sensors (temperature, humidity, shock, light) into a single tracking label device. This multi-functional integration allows one label to perform diverse tracking and monitoring functions, improving versatility while managing complexity through consolidation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple previously separate components (different communication modules, various sensors, battery, circuit board) into a single integrated tracking label. This merging reduces the overall system complexity by eliminating the need for multiple separate devices and simplifying the supply chain tracking infrastructure.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If batteries are continuously powered to enable real-time tracking, then tracking accuracy is improved, but power consumption increases

Engineering Contradiction:

Improvetracking accuracyVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic sampling of sensor data and periodic transmission of tracking information rather than continuous operation. The microcontroller activates sensors and communication interfaces at scheduled intervals, maintaining tracking accuracy over time while significantly reducing average power consumption compared to continuous operation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The tracking label autonomously manages its own power consumption by implementing sleep modes and activating components only when needed. The system automatically adjusts its operation based on tracking requirements, enabling real-time tracking capability while conserving battery power through intelligent power management.

Inventive Principle:

Principle #25Self-service

AI summary

A process for activating tracking labels of an item tracking system that uses a printer to activate labels as they are printed for use. Electronic tracking labels may have a removable portion that breaks an electrical circuit when removed; breaking the circuit activates the label. A printer with a label cutter may be used when labels are prepared for use, and the printer may be configured to cut off the removable portion of the label during label printing. This method automates label activation as part of the label preparation process. The printer may be programmed to position the boundary between the removable portion of the label and the rest of the label under the cutter, for example using knowledge of the label's layout. A printed, activated label output from the printer may be placed directly on an item to be tracked.
