Solution Overview

Problem

Current vent/intake systems for outdoor combustion facilities like firepits, chimineas, and grills are either aesthetically unpleasing, structurally inadequate, or excessively costly, posing safety hazards and deterring installation due to customization requirements and high costs.

Innovation Solution

A vent assembly comprising a face member and a support member with elastic deformation capabilities, allowing for easy installation and secure attachment without the need for extensive customization, while reducing shipping costs through nested configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If blocks are removed to create air intake holes, then airflow efficiency is improved, but structural support and aesthetic appearance deteriorate

Engineering Contradiction:
Improveairflow efficiencyVSAvoidstructural support
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The vent assembly is divided into separate components: a face member with openings for airflow and a support member with terminal portions that fit into the firepit wall. This segmentation allows the support function to be provided by the support member while the face member provides the airflow function, resolving the contradiction between structural support and airflow efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support member serves multiple functions: it provides structural support to maintain the firepit wall integrity, enables airflow through its configuration, and facilitates installation by fitting into the wall opening. This multi-functionality resolves the contradiction by combining support and airflow functions in a single integrated solution.

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

2Productivity

If blocks are removed to create air intake holes, then airflow efficiency is improved, but safety and aesthetic appearance deteriorate

Engineering Contradiction:
Improveairflow efficiencyVSAvoidsafety hazards from debris entry
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The face member has specific openings with controlled sizes and shapes that provide adequate airflow while preventing debris and objects from entering the firepit. This local quality control at the opening level resolves the contradiction by allowing airflow while blocking harmful factors.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The face member acts as an intermediary between the external environment and the firepit interior. It mediates the airflow need by providing controlled openings that allow air passage while blocking debris and objects, thus resolving the safety hazard without compromising airflow efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If custom vents are manufactured to fit specific firepits, then fit and support are improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvefit and supportVSAvoidcustomization requirements
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The vent assembly is designed as a universal component that can fit various firepit configurations. The support member's terminal portions fit into standard wall openings, and the face member provides adaptable airflow control. This universality reduces manufacturing complexity while maintaining reliable fit and support across different applications.

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

Solution Approach 2:

By segmenting the vent assembly into modular components (face member and support member), the system achieves adaptability to different firepit configurations without requiring custom manufacturing for each case. The modular design allows standard components to be combined to fit various applications, reducing both manufacturing complexity and cost.

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If extensive customization and drilling are required for vent installation, then fit precision is improved, but installation complexity and time increase

Engineering Contradiction:
Improvefit precisionVSAvoidinstallation complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The support member is pre-formed with terminal portions designed to fit into the firepit wall opening without requiring on-site drilling or cutting. The face member is pre-configured with appropriate openings for airflow and safety. This preliminary preparation of components resolves the contradiction by achieving precise fit through manufacturing precision rather than complex installation procedures.

Inventive Principle:
Principle #10Preliminary action

AI summary

A vent assembly for a firepit or other outdoor combustion facility includes a face member and a support member. The face member has a perimeter and a thickness in a direction orthogonal to the perimeter. The support member has a predetermined resilience allowing limited elastic deformation of the support member upon application of manual compressive force to the support member. Connectors on the face member and the support member cooperate to lock the face member and the support member to one another.
