Solution Overview

Problem

Traditional billboard advertising is limited by its stationary nature, which restricts the reach of advertisements to only those who pass by, whereas vehicle-mounted advertising can bring advertisements to consumers but lacks effective solutions for heat protection and power sustainability in outdoor environments.

Innovation Solution

A vehicle-mountable data display device featuring an enclosure with outward-sloped walls and windows housing video displays, a shield for heat protection and power generation via solar cells, and optional panels for static messaging, allowing for flexible display configurations and energy conservation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If video displays are mounted on a vehicle for mobile advertising, then advertisement reach is improved, but heat protection for electronics becomes problematic

Engineering Contradiction:

Improveadvertisement reachVSAvoidheat exposure to electronics

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The shield is positioned to block sunlight and heat before they reach the video displays and electronic components. This preliminary protective action prevents heat buildup and overheating of sensitive electronics while allowing the advertisement to remain visible to passing consumers.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The shield acts as an intermediary element between the external environment (sunlight, heat) and the electronic components (video displays). It mediates by filtering out harmful thermal radiation while permitting the advertisement content to be displayed and viewed by the target audience.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If video displays operate continuously for maximum visibility, then advertisement effectiveness is improved, but power consumption increases

Engineering Contradiction:

Improveadvertisement effectivenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The video displays operate periodically rather than continuously - turning on during nighttime or low-light conditions and turning off during daytime when natural visibility is sufficient. This periodic operation maintains advertisement effectiveness when needed while significantly reducing overall power consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The advertisement display adapts its visibility characteristics based on environmental lighting conditions. During daytime, the natural colors and lighting conditions provide sufficient visibility without power consumption. During nighttime, the video displays activate to provide illuminated visibility, effectively adapting the display's operational state to external conditions.

Inventive Principle:

Principle #32Color changes

3Loss of energy

If solar cells are added for power generation, then energy sustainability is improved, but device complexity increases

Engineering Contradiction:

Improveenergy sustainabilityVSAvoidsystem complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The shield structure serves multiple functions simultaneously: it provides heat protection for the electronics, acts as a mounting surface for solar cells to generate power, and maintains the structural integrity of the advertisement display system. This multi-functionality reduces the need for separate components and minimizes overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The solar cells are integrated into the existing shield structure rather than being added as separate components. The shield combines protective, structural, and power-generation functions into a single unified element, reducing device complexity while achieving energy sustainability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A device for displaying data is disclosed. The device includes a mount, and enclosure with two outward-sloped walls, and two video displays within the enclosure each facing outward through windows in the outward-sloped walls of the enclosure. A shield optionally couples to the enclosure via a post. Also, optionally, a solar battery couples to the solar cell to store energy from the solar cell. Further, a panel optionally couples to the enclosure, e.g., via a hinge, track system, etc. so the panel may selectively cover and not cover at least one of the video displays in the windows of the enclosure.
