Solution Overview

Problem

The installation of solar collectors in remote or disaster areas is challenging due to the lack of access to cranes and suitable tools, making it difficult to securely fasten them to masts without risking damage or injury.

Innovation Solution

A fastening device comprising a collector support, deflection device, winch device, and pulling element that allows for the secure attachment and detachment of solar collectors to masts using minimal tools, such as a ladder and hand crank, enabling easy alignment and clamping for optimal energy generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a crane is used to lift solar collectors to elevated locations, then installation safety and efficiency are improved, but equipment availability and cost increase significantly in remote areas

Engineering Contradiction:
Improveinstallation safetyVSAvoidequipment availability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary lifting mechanism consisting of a winch device, pulling element, and lift body that mediates between the ground-level installation team and the elevated solar collector mounting location. This intermediary system enables safe lifting without requiring heavy crane equipment, making the installation process adaptable to remote areas where cranes are unavailable.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The lifting function is segmented into separate components: a winch device for generating pulling force, a pulling element (rope/cable) for force transmission, and a lift body for directly engaging the solar collector. This segmentation allows each component to be independently optimized and assembled from portable parts, eliminating the need for a single large crane.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If solar collectors are manually assembled in individual parts without proper lifting equipment, then equipment requirements are reduced, but installation time and risk of damage or injury increase

Engineering Contradiction:
Improveequipment requirementsVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The solar collectors are prepared in advance by attaching them to collector carriers that include integrated lifting interfaces. The lift body is pre-configured with engagement mechanisms that match these interfaces. This preliminary preparation allows the collectors to be lifted as complete assemblies rather than requiring time-consuming on-site assembly of individual parts.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent combines multiple functions into integrated components: the collector carrier merges structural support with lifting interface functionality, and the lift body combines the pulling element attachment with the collector engagement mechanism. This merging reduces the number of separate assembly steps required during installation.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If solar collectors are mounted on ground-level stands, then accessibility for installation is improved, but theft risk and damage from unwanted access increase

Engineering Contradiction:
Improveinstallation accessibilityVSAvoidtheft risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent transitions the installation approach from ground-level horizontal assembly to vertical elevation using the mast structure. Solar collectors are mounted at elevated positions on vertical masts rather than at ground level, changing the spatial dimension from horizontal accessibility to vertical inaccessibility for potential thieves while maintaining installation feasibility through the portable lifting system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If complex fastening devices are used to securely attach solar collectors, then mounting reliability is improved, but device complexity and assembly difficulty increase

Engineering Contradiction:
Improvemounting securityVSAvoidfastening device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex lifting and positioning functions from the fastening device itself and places them in separate temporary installation aids (winch device, lift body, pulling element). The fastening device itself is simplified to focus only on its core function of securing the solar collector to the mast, while the lifting function is handled by the removable installation aid system.

Inventive Principle:
Principle #2Taking out (Extraction)
