Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple mobile devices are charged simultaneously using existing wireless charging technology, then the charging service coverage is improved, but the charging efficiency deteriorates and interruptions occur

Engineering Contradiction:
Improvecharging service coverageVSAvoidcharging efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the charging process by creating distinct communication and charging regions. Devices in the communication region perform preparation procedures (authentication, information exchange) before entering the charging region for actual power transfer. This segmentation allows multiple devices to be managed efficiently without interfering with each other's charging processes, thus maintaining high charging efficiency while serving multiple devices simultaneously.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If existing wireless charging systems charge multiple devices, then charging service coverage is improved, but system stability deteriorates due to interruptions

Engineering Contradiction:
Improvecharging service coverageVSAvoidsystem stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary actions by requiring devices to complete authentication, information exchange, and preparation procedures in the communication region before entering the charging region. This preliminary preparation ensures that only authorized and ready devices receive power, preventing interruptions and stability issues during the actual charging process. The base station can also plan and coordinate charging resources in advance for multiple devices.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If wireless charging is provided to all mobile devices in the charging region, then charging service coverage is improved, but energy waste increases due to unauthorized or unnecessary charging

Engineering Contradiction:
Improvecharging service coverageVSAvoidenergy waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements feedback mechanisms where devices in the communication region exchange information with the base station, including authentication status, battery state, and charging requirements. The base station uses this feedback information to determine which devices should be charged and allocate energy resources accordingly. This ensures that energy is provided only to authorized devices that actually need charging, preventing energy waste while maintaining comprehensive service coverage.

Inventive Principle:
Principle #23Feedback

AI summary

A wireless multi charging method and system are disclosed. The wireless charging method selects a portion of mobile devices (210, 220, 230) located in a charging region (A) as a group, and provides energy for wireless charging to the selected group of mobile devices. Accordingly, group charging is possible, and thus it is also possible to selectively charge mobile devices which allow charging.
