Solution Overview

Problem

Existing terrace canopies suffer from condensate droplets forming on the underside of panels or slats, which can fall on users or objects below, and rainwater is not effectively managed, leading to potential splashing and inefficient drainage.

Innovation Solution

A terrace canopy design featuring a rain gutter with an upright edge containing lips that extend to each slat or panel, accompanied by a condensation gutter parallel to the rain gutter, capturing and redirecting condensate to prevent it from reaching the underside and ensuring effective water management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If rain gutters are provided to capture and carry off rainwater, then rainwater drainage is improved, but condensate droplets still form on the underside of panels and fall on users

Engineering Contradiction:
Improverainwater drainage efficiencyVSAvoidcondensate droplets falling on users
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The gutter system is segmented into two distinct components: a rain gutter for collecting rainwater from the canopy surface, and a condensation gutter for capturing condensate from the underside of panels. This segmentation allows each gutter to address specific water management needs independently, preventing condensate from falling on users while maintaining effective rainwater drainage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The condensation gutter acts as an intermediary structure between the panel underside and the user space. It intercepts condensate droplets before they can fall onto users or objects, effectively mediating the harmful effect of condensate while allowing the rain gutter to continue its rainwater management function

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the terrace canopy is open on the sides for ventilation, then air circulation is improved, but outside temperature contact with panels increases condensate formation

Engineering Contradiction:
Improveventilation and air circulationVSAvoidcondensate formation on panels
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention converts the harmful effect of condensate formation into a manageable situation by providing the condensation gutter. The open-sided design that causes temperature contact and condensate formation is maintained for ventilation benefits, while the condensation gutter captures the resulting condensate, transforming the harmful moisture into a controlled drainage system

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If lips are provided on the upright edge to seal with slats, then lightproof and airtight sealing is improved, but water management complexity increases

Engineering Contradiction:
Improvelightproof and airtight sealingVSAvoidgutter structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The upright edge with lips is designed to perform multiple functions simultaneously: it provides lightproof and airtight sealing by contacting the slats, while also serving as the mounting structure for the condensation gutter. This multi-functionality achieves reliable sealing without proportionally increasing structural complexity, as the same vertical edge serves both sealing and condensate management purposes

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