Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple specialized cleaning devices are manufactured for different solar system types and sizes, then cleaning effectiveness for specific systems is improved, but device complexity and manufacturing costs increase

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

Solution Approach 1:

The cleaning device is designed with a modular construction where the cleaning module can be universally applied to different solar system types (elevated solar fields, roof systems, segment systems) and sizes. The module comprises a longitudinal member with cross members that can be detached and repositioned, allowing a single device design to serve multiple cleaning applications without requiring specialized devices for each system type.

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

Solution Approach 2:

The cleaning device is divided into separable modules, with the cleaning module being detachably connectable to different longitudinal members. This segmentation allows the cleaning module to be reused across different device configurations and solar system types, reducing the need to manufacture multiple specialized devices while maintaining cleaning effectiveness.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If different cleaning devices are used for different solar module sizes, then cleaning precision is improved, but loss of time and operational efficiency worsen due to needing multiple devices

Engineering Contradiction:
Improvecleaning precisionVSAvoidoperational time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The cleaning module is designed to be dynamically reconfigurable on the longitudinal member. Cross members can be detached and repositioned to different locations along the longitudinal member to adapt the cleaning width to match different solar module sizes. This dynamic adjustment capability allows a single device to maintain cleaning precision across various module sizes without requiring multiple specialized devices, thereby reducing operational time and device changes.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a fixed design cleaning device is used, then manufacturing cost is reduced, but adaptability to different solar system types and sizes is limited

Engineering Contradiction:
Improvemanufacturing costVSAvoidadaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cleaning device employs a segmented modular design where the cleaning module is a standardized component that can be detachably connected to different longitudinal members. This segmentation enables the cleaning module to be manufactured once and reused across various device configurations for different solar system types and sizes, maintaining ease of manufacture while significantly improving adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates dynamic adjustment capabilities through detachable cross members that can be repositioned along the longitudinal member. This allows a single standardized cleaning module design to adapt to different solar system configurations and module sizes without requiring custom manufacturing, thus maintaining low manufacturing costs while achieving high versatility.

Inventive Principle:
Principle #15Dynamics
