Solution Overview

Problem

Existing modular pergolas suffer from structural looseness and water leakage in interface connections, compromising stability and waterproofing performance.

Innovation Solution

The modular courtyard pergola employs inclined sockets on crossbeams that form openings to connect with column sockets, using upper and lower connectors to enhance stability and flexibility, and incorporates a cover plate and drainage assembly to minimize water ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If direct connection between crossbeams and columns is used, then assembly is simple, but structural stability is insufficient

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

Solution Approach 1:

The patent introduces a connecting assembly as an intermediary component between crossbeams and columns. This connecting assembly includes connection pieces with inclined sockets that mate with column sockets, providing a stable interface without requiring direct complex welding or bolting between structural members. The connection piece acts as a mediator that simplifies the overall assembly while ensuring structural stability through precise geometric fitting.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If modular components are used, then transportation and assembly are convenient, but interface connections suffer from looseness and water leakage

Engineering Contradiction:
Improveassembly convenienceVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connecting assembly is nested within the joint interface between crossbeams and columns. The connection pieces with inclined sockets are inserted into column sockets, and crossbeams are then nested onto these connection pieces. This nested arrangement creates multiple levels of interference fit and mechanical interlocking, preventing looseness while maintaining modular assembly convenience. The nested structure also naturally shields the connection interface from water ingress.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Strength

If connection area is increased, then connection strength is improved, but device complexity increases

Engineering Contradiction:
Improveconnection strengthVSAvoidconnection structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent employs inclined sockets at 45 degrees that extend in multiple spatial dimensions. This angular, multi-dimensional configuration allows the connection interface to engage across several dimensions simultaneously, increasing the effective connection area and strength without requiring a larger or more complex assembly structure. The inclined geometry transforms a simple socket insertion into a multi-dimensional mechanical lock.

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