Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID devices transmit RF signals at a single constant power level, making it difficult to create a personalized location-based experience as they either activate too many or too few interactive attractions, leading to inefficiencies in power usage and inability to integrate with multiple activation fields.
Innovation Solution
A multi-power signaling device capable of emitting RF signals at various power levels, selected by a processor, to optimize signal range and relevance, incorporating a memory to manage signal transmission and detect activation fields for precise interaction with the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If RFID devices transmit RF signals at the highest power level, then the signal range is maximized to reach all receivers within 300 meters, but too many interactive attractions outside the proximity of the guest are activated, resulting in needless waste of power usage
Solution Approach 1:
The RFID device dynamically adjusts its transmit power level based on the detected location and proximity to interactive attractions. Instead of using a fixed highest power level, the system selects appropriate power levels (e.g., first power level for distant attractions, second power level for nearby attractions) to activate only relevant attractions, thereby reducing unnecessary energy consumption while maintaining adequate signal range when needed.
2Loss of energy
If RFID devices transmit RF signals at the lowest power level, then power usage is minimized, but too few attractions are activated to operate for the guest's interactive experience
Solution Approach 1:
The system dynamically selects between different power levels based on the guest's location and the distribution of interactive attractions. When the guest is near attractions, the device uses higher power levels to ensure adequate activation. When the guest is distant from attractions, the device uses lower power levels to conserve energy, thus adapting the power consumption to the actual operational needs.
3Device complexity
If RFID devices transmit RF signals at a single fixed power level, then the device complexity is minimized, but the device is too inflexible to create a personalized location-based experience
Solution Approach 1:
The RFID device incorporates a processor that receives location information and automatically selects appropriate power levels from multiple predefined levels. This dynamic power adjustment capability enables the device to create personalized location-based experiences by activating relevant attractions based on the guest's position, while the use of predefined power levels keeps the implementation relatively simple.
Solution Approach 2:
The system changes the transmit power parameter based on location data. The processor modifies the power level parameter (selecting from first power level, second power level, etc.) according to the detected guest location and proximity to attractions, thereby enabling flexible location-based experiences without requiring complex reconfiguration of the device.
4Area of stationary object
If all interactive attractions within 300 meters are activated by high power level signals, then the signal coverage is maximized, but the unnecessary activation of attractions leads to waste of power usage
Solution Approach 1:
The system applies different power levels to different spatial regions. Instead of uniformly activating all attractions within the maximum range, the device selectively activates attractions based on the guest's local position. The processor determines which attractions are relevant based on proximity and activates them at appropriate power levels, thereby reducing unnecessary energy consumption while maintaining adequate coverage for the guest's immediate surroundings.

AI summary
There is provided a system and method for operating multi-power signaling device. There is provided a system comprising a memory, a transmitter, and a processor. The processor chooses a power level from a plurality of transmit power levels to be used as the strength for broadcasting the next signal to be broadcasted. The selected power level value is converted into a digital value and inserted into the data content of the signal to be broadcasted. The transmitter broadcasts the signal at the strength of the prior selected power level.
