Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If Bluetooth Low Energy (BLE) technology is used for beacon devices, then power consumption is reduced and device portability is improved, but transmission range is limited to 30-50 ft and network coverage requires many more devices

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork coverage area

Core Design Contradiction:

Use of energy by moving objectVSArea of stationary object

Solution Approach 1:

The patent combines BLE and Wi-Fi Direct technologies in a hybrid communication system. BLE is used for initial device discovery and connection establishment due to its low power consumption, while Wi-Fi Direct is activated for actual data transmission to achieve longer range and better coverage without proportionally increasing device count

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The beacon device is designed with multi-functional communication capabilities, supporting both BLE and Wi-Fi Direct protocols. This allows the same device to serve multiple functions: low-power beaconing for discovery and high-range data transmission, reducing the total number of devices needed for comprehensive coverage

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of stationary object

If more beacon devices are deployed to compensate for short range, then network coverage is improved, but placement complexity and cost increase significantly

Engineering Contradiction:

Improvenetwork coverage areaVSAvoiddeployment complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

By merging BLE and Wi-Fi Direct in a single device, the patent achieves extended coverage without deploying additional devices. The hybrid approach allows each device to cover a larger effective area, reducing the total deployment count and associated complexity

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If Bluetooth technology constraints are accepted, then device simplicity is maintained, but data transmission range and capability are limited

Engineering Contradiction:

Improvedevice simplicityVSAvoidtransmission range

Core Design Contradiction:

Device complexityVSLength of stationary object

Solution Approach 1:

The device maintains simplicity by using standard off-the-shelf components (BLE and Wi-Fi modules) that are universally available. The multi-functional design allows the same simple device architecture to achieve extended range through protocol switching rather than complex custom hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If traditional beacon devices are used, then implementation is straightforward, but security vulnerabilities exist due to spoofable beacon IDs

Engineering Contradiction:

Improveimplementation easeVSAvoidsecurity reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces an intermediary verification mechanism where the mobile device acts as a mediator between multiple beacon devices. The mobile device receives beacon IDs from multiple sources, correlates them with signal strength data, and uses algorithms to identify the authentic beacon, preventing spoofing attacks

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback through signal strength correlation and cross-validation of beacon IDs received from multiple devices. The mobile device continuously monitors signal characteristics and uses this feedback to verify beacon authenticity and maintain secure operation

Inventive Principle:

Principle #23Feedback
