Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If GPS-based location tracking systems are used, then location tracking capability is improved, but cost and implementation effort increase

Engineering Contradiction:
Improvelocation tracking capabilityVSAvoidimplementation effort
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces GPS satellite-based electromagnetic positioning with a local optical messaging system using LEDs and photodetectors. The system uses light-based communication to transmit location information within a confined space, eliminating the need for GPS hardware and satellite dependency, thereby reducing implementation complexity while maintaining location tracking capability.

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

Solution Approach 2:

The patent introduces messaging units with light sources as intermediaries between the tracking system and the target object. These units transmit location codes through light modulation, serving as a local mediator that enables precise location tracking without requiring direct GPS satellite communication, thus reducing cost and implementation effort.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional messaging systems are used, then message delivery is achieved, but location-based personalization capability is insufficient

Engineering Contradiction:
Improvemessage personalization capabilityVSAvoidlocation context information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements location-specific messaging by assigning different messages to different spatial locations within the environment. Each messaging unit broadcasts messages tailored to its specific location, enabling personalized communication based on the recipient's precise location context, thereby enhancing message adaptability while preserving location information.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses feedback from location detection to dynamically select and broadcast appropriate messages. The messaging units receive location information and adjust their message content accordingly, creating a closed-loop system that continuously adapts messages based on real-time location data, improving personalization capability.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If light-based messaging is implemented, then location-based message targeting precision is improved, but system complexity increases

Engineering Contradiction:
Improvemessage targeting precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs multi-functional messaging units that combine light emission, light modulation, and message broadcasting capabilities in a single integrated system. These units serve multiple purposes including location identification, message transmission, and personalization, thereby achieving high targeting precision without proportionally increasing system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses periodic light modulation to encode and transmit messages. By modulating the light source at specific frequencies and patterns, the system achieves precise message delivery to targeted locations while using simple, repeatable modulation cycles that reduce the complexity of the control mechanism.

Inventive Principle:
Principle #19Periodic action

AI summary

Provided is a messaging system that includes: messaging units disposed in different locations within a commercial space, each including a light-emitting diode (LED); a messaging/modulation controller coupled to the LED and configured to turn the LED on and off so as to broadcast a digital message as a binary-encoded digital signal corresponding to on/off states of the LED; and a user interface, coupled to the messaging/modulation controller, that permits a user to create schedules that specify how and when specified messages are to be broadcast by such messaging units. Different ones of the messaging units are configured to broadcast different digital messages, including substantive content that is different from what is broadcast by other ones of the messaging units, in accordance with the schedules input through the user interface.
