Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If paper-based advertisements are used on vehicles, then the advertisement content can be displayed, but it takes time to install and remove the advertisements

Engineering Contradiction:

ImproveAdvertisement installation and removal efficiencyVSAvoidTime required for advertisement placement and removal

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical paper-based advertisement system with an electronic display system. The frame structure with integrated screens (first and second display units) eliminates the need for physical advertisement installation and removal, allowing digital content to be updated instantly through electronic means.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The advertisement system transitions from static paper advertisements to dynamic electronic displays. The display units can show changing content, and the system can be quickly reconfigured by changing digital content rather than physically replacing advertisements, enabling rapid adaptation to different advertising needs.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multimedia display units are installed in the vehicle advertisement device, then advertisement playback capability is enhanced, but heat generation increases requiring heat dissipation mechanisms

Engineering Contradiction:

ImproveAdvertisement playback capabilityVSAvoidHeat generation from display units

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

The gas guide units act as intermediaries between the heat-generating display units and the external environment. The guide units channel airflow to efficiently remove heat from the display units, mediating the thermal management needs of the electronics while maintaining their high-performance capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses pneumatic principles through the gas guide units and fans to create forced convection airflow. This pneumatic system actively moves air across the display units to dissipate heat, allowing the multimedia displays to operate at high performance levels without overheating.

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Adaptability or versatility

If the device is designed for outdoor vehicle mounting, then advertisement playback is enabled ubiquitously, but protection against environmental factors (waterproofing) is required

Engineering Contradiction:

ImproveUbiquitous advertisement playback on vehiclesVSAvoidEnvironmental exposure to water and weather

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs sealing structures and protective coverings (implied by the frame and casing design) that act as flexible barriers against environmental factors. These protective elements shield the electronic components from water and weather while allowing the device to maintain its outdoor vehicle mounting functionality.

Inventive Principle:

Principle #30Flexible shells and thin films

4Productivity

If communication interfaces are integrated for remote data transmission, then advertisement data can be transmitted instantly, but device complexity increases

Engineering Contradiction:

ImproveAdvertisement data transmission speedVSAvoidCommunication interface integration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The link unit is designed as a multi-functional communication interface that can handle various data transmission protocols and modes. This universal interface consolidates multiple communication functions into a single integrated component, reducing overall system complexity while enabling instant advertisement data transmission through multiple communication channels.

Inventive Principle:

Principle #6Universality (Multi-functionality)
