Solution Overview

Problem

Existing solar collectors have standardized dimensions due to the limitations of moulding processes, which restrict their adaptability to specific requirements and hinder efficient manufacturing.

Innovation Solution

The use of angular joints made from a single flat sheet of aluminium or alloys, which are bent and profiled to form the sides of the solar collector pan, allowing for customizable dimensions and improved structural stiffness, sealing, and handling through a simplified manufacturing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If moulding processes are used to manufacture solar collector pans, then manufacturing efficiency is improved, but the dimensions and size of the solar collector are constrained and standardized

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidadaptability to specific requirements
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The solar collector pan is divided into modular components: a base part and side parts that can be assembled together. The side parts can be configured in different numbers and arrangements to create various pan dimensions and shapes, enabling customization while maintaining efficient manufacturing of standardized modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces adjustable and reconfigurable side parts that can be attached to the base part in different configurations. This dynamic assembly approach allows the same base component to serve multiple dimension requirements, transforming a static moulding process into a flexible assembly system.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple moulds are created to achieve different dimensions, then adaptability is improved, but manufacturing complexity and costs increase

Engineering Contradiction:
Improverange of dimensionsVSAvoidnumber of moulds
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single base part design serves multiple functions by accommodating different configurations of side parts. This universal base component can be used across various solar collector models, eliminating the need for multiple specialized moulds while maintaining the ability to produce different dimensions.

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

Solution Approach 2:

By segmenting the pan into a standardized base part and configurable side parts, the invention reduces the number of moulds needed. Instead of creating unique moulds for each dimension combination, only the base part requires a mould, while side parts can be produced using fewer standardized moulds and then assembled in different configurations.

Inventive Principle:
Principle #1Segmentation

3Strength

If angular joints are used to connect pan sides, then structural stiffness is improved, but device complexity increases

Engineering Contradiction:
Improvestructural stiffnessVSAvoidnumber of components
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The angular joint is integrated directly into the base part through injection moulding, combining what would otherwise be separate components into a single monolithic piece. This merging approach maintains the structural stiffness benefits of angular joints while eliminating the complexity of assembling separate joint components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base part is manufactured using composite materials (polypropylene and glass fibre) that provide high structural stiffness and strength. This material selection allows the base part to serve as both a structural element and a mounting platform for side parts, reducing the need for additional reinforcing components.

Inventive Principle:
Principle #40Composite materials

AI summary

The object of the present invention is an angular joint for forming the pan of said solar collector. Said angular joint (1) mainly acts as joining element for the sides (21, 22, 23) of said pan (2), imparting the structural stiffness to the latter required for the purposes thereof. Said angular joint (1) further provides support to at least the absorber and the glazed cover of the solar collector, ensures the seal against water infiltrations (and the optional drainage thereof) and provides improved means for handling and properly installing and protecting the same solar collector.
