Solution Overview

Problem

Existing solutions for connecting transparent panels in roofing systems result in a high overall thickness due to overlapping ends, leading to potential infiltrations and alignment issues.

Innovation Solution

A connecting element with a main portion and lateral portions that connect to supporting portions, allowing for easy installation of transparent panels next to each other without overlapping their constraining ends, thus reducing the covered area and ensuring stable connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If transparent panels are connected by overlapping their ends, then the connection is simple, but the overall thickness increases leading to infiltrations and alignment problems

Engineering Contradiction:
Improveconnection simplicityVSAvoidoverall thickness
Core Design Contradiction:
Device complexityVSLength of stationary object

Solution Approach 1:

The connecting element is divided into distinct functional portions: a main portion for structural support and lateral portions for connecting to adjacent panels. This segmentation allows each part to perform its specific function efficiently, reducing the need for overlapping and thereby reducing overall thickness while maintaining connection simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting element acts as an intermediary component between adjacent transparent panels. Instead of directly overlapping panel ends, the connecting element mediates the connection through its lateral portions that attach to the lateral surfaces of the panels, eliminating the thickness issue caused by direct overlapping while preserving connection simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If transparent panels are connected using conventional methods, then connection is achieved, but alignment precision deteriorates due to high thickness

Engineering Contradiction:
Improveconnection stabilityVSAvoidpanel alignment
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The connection transitions from a vertical overlapping arrangement (thickness direction) to a lateral attachment arrangement (width direction). The lateral portions of the connecting element attach to the lateral surfaces of the panels, moving the connection interface to another dimension and thereby improving alignment precision while maintaining connection stability.

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

3Reliability

If panel ends overlap to connect transparent panels, then connection is formed, but the covered area increases due to reduced transparency

Engineering Contradiction:
Improveconnection stabilityVSAvoidtransparent area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The connecting element serves as an intermediary that connects panels laterally without requiring vertical overlap. This eliminates the need for thick connection zones that would block light, thereby preserving the transparent area while maintaining connection stability through the lateral attachment mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
