Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional solar mounting systems are used, then secure mounting of solar modules is achieved, but installation becomes laborious and time-consuming requiring skilled installers

Engineering Contradiction:
Improvesecure mountingVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting system is divided into separate modular components: mounting brackets that attach to the torque tube, and retainer assemblies that secure the solar modules. These segments can be independently installed and positioned, allowing installers to work with smaller, more manageable parts rather than attempting to install large rigid structures, thereby reducing installation complexity while maintaining secure mounting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retainer assembly incorporates a movable retainer element that can be positioned in different states (open/closed, engaged/disengaged) to facilitate installation and removal of solar modules. This dynamic component allows the mounting system to transition between secure holding and easy release states, enabling non-skilled installers to quickly install and maintain modules without specialized tools or expertise.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional solar mounting systems are used, then solar modules are securely fixed, but component cost and shipping cost increase due to weight and size

Engineering Contradiction:
Improvemodule fixationVSAvoidpackaging and shipping efficiency
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By segmenting the mounting system into smaller components (mounting brackets, retainer assemblies, individual fasteners), the system achieves secure module fixation while improving packaging efficiency. Smaller parts can be compactly packaged, reducing shipping volume and weight costs compared to traditional bulky mounting structures, while still providing reliable mechanical attachment when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retainer assembly components are designed to nest within each other when not in use - the retainer element stores within the mounting bracket, and fasteners are contained within the assembly structure. This nesting arrangement minimizes the overall volume required for shipping and storage while maintaining the structural integrity and secure fixation capability when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If complex mounting systems are used, then secure positioning is achieved, but installation time and labor costs increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The mounting brackets are pre-configured with attachment features for the torque tube, and the retainer assemblies are pre-assembled with their fastening components. This preliminary preparation allows installers to simply attach the pre-configured brackets to the torque tube and then secure the modules using the pre-assembled retainers, eliminating the need for complex field assembly operations and significantly increasing installation speed while maintaining accurate positioning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The retainer assembly is designed as a self-contained unit that automatically secures the solar module when the retainer element is positioned in the engaged state. The system's own components work together to achieve secure positioning without requiring external tools, specialized skills, or complex adjustment procedures, thereby enabling rapid installation by non-skilled workers while ensuring accurate and reliable module positioning.

Inventive Principle:
Principle #25Self-service
