Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual cleaning methods are used for solar panels, then cleaning can be performed, but labor costs and maintenance complexity increase

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidmaintenance complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables solar panels to clean themselves by integrating fluid reservoirs, dispensers, and collectors directly onto the panel structure. The panel autonomously receives pressurized cleaning fluid through integrated dispensers and collects runoff through integrated collectors, eliminating the need for external manual cleaning operations and reducing long-term maintenance complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning system integrates multiple functions into a single unified structure mounted on the solar panel. The integrated assembly includes fluid storage reservoirs, pressurized dispensing mechanisms, cleaning fluid application systems, and runoff collection channels, all combined in one multi-functional unit that performs storage, pressurization, cleaning, and collection operations.

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

2Productivity

If cleaning frequency is increased to maintain panel efficiency, then energy output is improved, but water consumption and operational costs increase

Engineering Contradiction:
Improveenergy outputVSAvoidwater consumption
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The system recovers and reuses cleaning fluid through integrated collectors that capture runoff from the panel surface. The collected fluid can be filtered and reused in subsequent cleaning cycles, reducing overall water consumption. The system also recovers thermal energy from the cleaning fluid through heat exchange mechanisms, converting waste thermal energy into useful heating or cooling.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The system changes the physical parameters of cleaning fluid by adjusting pressure, temperature, and flow rate based on detected panel conditions. Sensors monitor dirt accumulation levels and environmental conditions, then the system adjusts fluid pressure and temperature accordingly, using higher pressure for heavily soiled panels and lower pressure for lightly soiled panels, thereby optimizing water usage.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If pressurized fluid systems are used for cleaning, then cleaning effectiveness is improved, but system complexity and initial cost increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system merges the pressurization mechanism, fluid storage, dispensing, and collection functions into an integrated assembly mounted directly on the solar panel. By combining these previously separate components into a single unified system, the patent reduces overall system complexity while maintaining cleaning effectiveness through coordinated operation of all integrated parts.

Inventive Principle:
Principle #5Merging (Combining)
