Solution Overview

Problem

Existing support devices for solar trackers with welded attachments are costly and complex, slowing manufacturing and complicating installation and assembly due to the use of hinges and welded parts.

Innovation Solution

A support device with a clamp comprising a lower clamp section and opposite side clamp sections, connected via screws and hooks, allowing for clamping and adjustment without hinges, fabricated using sheet metal stamping for simplified assembly and increased production efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welded attachments are used in the support device, then the structural strength is improved, but the manufacturing cost increases and production speed decreases

Engineering Contradiction:
Improvestructural strengthVSAvoidproduction speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The patent replaces welded attachments with mechanical fastening elements (screws, bolts, and clamps) to join the clamp sections to the support plate. This substitution eliminates the need for welding operations, thereby increasing production speed and reducing manufacturing costs while maintaining structural integrity through proven mechanical connection methods.

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

2Stability of the object's composition

If welded attachments and hinges are used in the support device, then the structural stability is improved, but the device complexity increases and installation difficulty increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The clamp is divided into multiple separate sections (first clamp section, second clamp section, third clamp section) that are independently formed and then mechanically assembled using fastening elements. This segmentation eliminates the need for complex welded attachments and hinges, reducing device complexity while maintaining structural stability through the distributed fastening system.

Inventive Principle:
Principle #1Segmentation

3Strength

If welded attachments are used in the support device, then the structural integrity is improved, but the manufacturing cost increases

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent replaces expensive welded attachments with standard mechanical fastening elements (screws, bolts, and clamps) that can be easily manufactured and assembled. This substitution significantly reduces manufacturing costs while maintaining structural integrity through proven mechanical connection methods that are both strong and reversible.

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

4Strength

If hinges and welded parts are used in the support device, then the structural strength is improved, but the installation and assembly tasks become complicated

Engineering Contradiction:
Improvestructural strengthVSAvoidinstallation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The clamp is divided into multiple separate sections that can be independently handled and assembled. This segmentation, combined with the use of simple mechanical fastening elements instead of welded attachments and hinges, greatly simplifies installation and assembly tasks while maintaining structural strength through the distributed fastening system.

Inventive Principle:
Principle #1Segmentation
