Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If extensive cabling and battery replacement are used to power multiple display devices, then the display devices can be powered, but the installation effort and costs increase significantly

Engineering Contradiction:
Improvepower supply capabilityVSAvoidcabling complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The system divides the power supply function into modular components: individual display devices can be independently powered through the channel system, and the solar power source is separated as an independent energy generation unit. This segmentation allows flexible configuration and reduces overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The channel system serves multiple functions simultaneously: it provides mechanical support for display devices, establishes electrical connections through integrated conductors, and enables power distribution from the solar source to multiple devices. This multi-functionality eliminates the need for separate cabling systems.

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

2Reliability

If individual power supplies are provided for each display device, then each device can operate independently, but the installation effort increases greatly

Engineering Contradiction:
Improveindependent operationVSAvoidinstallation effort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system merges the power distribution function into the mechanical channel structure. Electrical conductors are integrated directly into the channel, combining mechanical support and electrical connection functions. This allows independent operation of display devices while dramatically reducing installation effort compared to separate power supplies.

Inventive Principle:
Principle #5Merging (Combining)

3Use of energy by moving object

If batteries are used to power display devices, then portable power is achieved, but battery replacement is labor-intensive and unsustainable

Engineering Contradiction:
Improveportable powerVSAvoidmaintenance efficiency
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The solar power source provides self-sustaining energy generation without requiring external battery replacement. The system harvests solar energy directly to power display devices, eliminating the maintenance burden of battery replacement while maintaining portable, wireless operation capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical battery replacement system with a solar energy harvesting system. Instead of manually replacing depleted batteries, the system uses photovoltaic conversion to generate electricity continuously, substituting a passive energy storage mechanism with an active energy generation mechanism that requires no maintenance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If solar power source is used to energize display devices, then sustainability is improved, but electrical connection complexity may increase

Engineering Contradiction:
ImprovesustainabilityVSAvoidelectrical connection
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The solar power source and display device power supply are merged through the channel system with integrated conductors. This single integrated connection provides both mechanical mounting and electrical power distribution, achieving sustainability without increasing electrical connection complexity.

Inventive Principle:
Principle #5Merging (Combining)
