Solution Overview

Problem

Existing gutters for pergolas and similar structures are inadequate in guiding and supporting rainwater drainage, leading to water damage and rust, and lack features for quick assembly and disassembly, adaptability, and effective water management.

Innovation Solution

The invention introduces a five-device-in-one anti-leaking, anti-twisting, anti-warping, anti-vibrating double-locking double-core double-deck double-stacked internal-gutters system, featuring 4 side-rainwater-guiding and 2 end-rainwater-guiding quick-release-accessory-adding double-deck double-stacked-internal-gutters, double-deck-locking double-core-aligning double-tunnels, double-core-locking double-core-aligning spines, compression-locking gutter-aligning pegs, anti-twisting anti-warping anti-vibrating 90-degree-double-yokes, double-gutter-supporting-and-locking corner and center parapet-posts, and expandable foot-locking sleeve-bolt systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional gutters are used for pergolas, then rainwater drainage is provided, but water damage and rust occur due to inadequate guiding and supporting

Engineering Contradiction:
Improvewater damage preventionVSAvoidgutter system adequacy
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple gutter components (internal gutters, external gutters, support brackets, alignment features) into an integrated system that works together to prevent water damage and rust through coordinated rainwater drainage and structural support

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gutter system is divided into segmented components including internal gutters, external gutters, support brackets, and alignment features that can be manufactured separately and assembled together to form a complete water damage prevention system

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If existing gutter systems are used, then basic drainage is achieved, but quick assembly and disassembly is not possible

Engineering Contradiction:
Improveassembly speedVSAvoidgutter system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Alignment features such as alignment pins and alignment grooves are pre-formed on gutter components during manufacturing, enabling quick and accurate assembly without requiring complex alignment procedures or additional fastening steps

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Support brackets serve as intermediary components that simplify the connection between gutter systems and pergola structures, enabling quick assembly by providing pre-configured mounting interfaces that eliminate complex installation procedures

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If simple gutter systems are used, then assembly is straightforward, but adaptability to various structures (pergolas, RVs, houses, solar panels, concert stages) is limited

Engineering Contradiction:
Improvestructure compatibilityVSAvoidgutter system configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gutter system is designed with universal support brackets and adjustable components that can be configured to accommodate multiple structure types including pergolas, RVs, houses, solar panels, and concert stages, enabling a single system design to serve multiple applications

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

Solution Approach 2:

The gutter system incorporates adjustable and reconfigurable components that can be dynamically adapted to different structural configurations and mounting requirements, allowing the same basic system to be customized for various applications without requiring completely different designs

Inventive Principle:
Principle #15Dynamics
