Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional electronic display devices are used to replace paper schedules, then information can be updated electronically, but the devices require expensive wired power connections and infrastructure

Engineering Contradiction:

Improveinformation update efficiencyVSAvoidpower connection requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical wired power connection system with a wireless power transfer system using electromagnetic fields. The display device receives power wirelessly through electromagnetic induction, eliminating the need for physical power outlets and wired connections, thus reducing infrastructure requirements while maintaining continuous power supply for electronic displays

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The display device integrates multiple functions including wireless power reception, electronic display, and wireless communication capabilities into a single unit. This multi-functional design allows the device to operate independently without requiring separate power infrastructure, network wiring, or manual intervention for updates

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If battery-powered display devices are used, then wireless operation is achieved, but batteries require periodic replacement and pose environmental risks

Engineering Contradiction:

Improvewireless operationVSAvoidenvironmental risks from batteries

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The display device performs self-charging by continuously receiving wireless power transmission from a base station. The device automatically manages its own power supply without requiring user intervention for battery replacement or charging, eliminating harmful batteries while maintaining wireless operation through sustained electromagnetic power transfer

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of using disposable batteries that create waste, the system recovers and stores energy continuously in a rechargeable energy storage component within the display device. The base station continuously transmits power that is stored and reused, eliminating the need to discard batteries while maintaining portable wireless operation

Inventive Principle:

Principle #34Discarding and recovering

3Reliability

If grid-powered display devices are used, then continuous power supply is ensured, but installation requires costly infrastructure updates and wired connections

Engineering Contradiction:

Improvepower supply continuityVSAvoidinstallation cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent substitutes the mechanical wired power delivery infrastructure with a wireless electromagnetic power transmission system. The base station transmits power through the air using electromagnetic fields, allowing display devices to receive continuous power without physical connections, thereby eliminating costly wiring and outlet installation while ensuring uninterrupted power supply

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless base station acts as an intermediary between the power source and the display device. It converts electrical power into electromagnetic signals that can be wirelessly transmitted and received, serving as a mediator that eliminates the need for direct wired connections while maintaining reliable power delivery to multiple devices simultaneously

Inventive Principle:

Principle #24Intermediary (Mediator)
