Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless charging pads are used to charge wireless communication devices, then charging convenience is improved, but portability deteriorates and device size increases

Engineering Contradiction:
Improvecharging convenienceVSAvoidportability
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The wireless communication device is designed to serve dual functions: it acts as both a communication device and a wireless charging pad. The back surface of the device contains wireless charging circuitry that can charge other wireless communication devices, eliminating the need for separate charging pads while maintaining portability.

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

Solution Approach 2:

The patent combines the charging function with the communication device itself. Instead of having separate charging equipment, the communication device integrates wireless charging capability into its structure, merging two functions (communication and charging) into a single portable unit.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If users carry extra charging equipment to charge wireless communication devices, then charging capability is improved, but device complexity and clutter increase

Engineering Contradiction:
Improvecharging capabilityVSAvoidcharging paraphernalia
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the charging function from external charging equipment and integrates it directly into the wireless communication device. This eliminates the need to carry separate chargers, cables, and power adapters, reducing clutter while maintaining charging capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The wireless communication device can charge other devices using its own integrated wireless charging capability. The device serves itself and other devices without requiring external charging paraphernalia, making the system self-sufficient.

Inventive Principle:
Principle #25Self-service

3Reliability

If duplicate message transmissions are sent to multiple communication devices, then message delivery reliability is improved, but data throughput and resource utilization deteriorate

Engineering Contradiction:
Improvemessage deliveryVSAvoiddata throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system uses feedback mechanisms where the server receives status information from communication devices about their charging state and message reception status. Based on this feedback, the server intelligently determines whether to send duplicate messages or rely on device-to-device synchronization, optimizing both reliability and resource utilization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Instead of always sending duplicate messages to all devices, the system applies partial action by sending messages only when necessary. When devices are in close proximity and one has received the message, duplicate transmissions are avoided, reducing network traffic while maintaining adequate message delivery through device-to-device communication.

Inventive Principle:
Principle #16Partial or excessive action
