Packing Member with Flanges to Block Air Flow and Prevent Fire Spread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking apparatuses face the risk of fires due to the ignition of packing materials and manuals when operated with them still inside, as existing packing solutions fail to reliably extinguish fires, allowing them to spread.
Innovation Solution
A packing member with flanges covering the inlet and outlet of the cooking apparatus, made of materials like paper or Styrofoam, which includes a cutoff switch and fan control to stop operation and prevent air flow, ensuring fire extinguishment by blocking external air intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the packing member is made of combustible materials like paper or Styrofoam for effective packing, then the packing function is improved, but the fire risk increases when the apparatus is operated with the packing member inside
Solution Approach 1:
The packing member is divided into multiple functional parts: a body portion for packing and flanges for fire safety. The flanges are separated elements that can cover air inlets and outlets independently, allowing the packing function to remain while adding fire protection capability.
Solution Approach 2:
The flanges act as intermediary elements between the combustible packing material and the external environment. By covering the air inlets and outlets, the flanges mediate the interaction between oxygen supply and the packing material, preventing fire propagation even when the packing material itself is combustible.
2Reliability
If the flange covers the entire inlet and outlet to prevent fire spread, then fire safety is improved, but the air flow for cooking operation is restricted
Solution Approach 1:
The flanges are designed to cover only portions of the air inlets and outlets rather than completely blocking them. This partial coverage is sufficient to contain fire within the cooking chamber while still allowing adequate air flow for normal cooking operations. The excessive coverage would completely block air flow, but the optimal partial coverage achieves both fire safety and cooking functionality.
3Ease of manufacture
If the packing member structure is simplified without flanges for easy manufacture, then manufacturing cost is reduced, but the fire extinguishing capability is lost
Solution Approach 1:
The fire safety function is merged with the existing packing member structure by integrating flanges into the body portion. Rather than creating a separate fire protection device, the flanges are combined with the packing member itself, achieving fire safety without significantly increasing manufacturing complexity or cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents fire spread by blocking air flow and disconnecting power, ensuring safe operation even if the packing member and manual are left inside during use.
Implementation Method 1
the flange is provided to cover at least a portion of an inlet formed at one side of the cooking apparatus to allow external air to be introduced into the cooking apparatus
Implementation Method 2
a first flange to cover at least a portion of the outlet

AI summary
A packing member having a structure capable of reliably extinguishing a fire generated in a cooking apparatus and a cooking apparatus having the packing member are provided. The packing member for packing components of a cooking apparatus includes a flange formed by bending at least one side thereof. The flange is provided to cover at least a portion of an inlet formed at one side of the cooking apparatus to allow external air to be introduced into the cooking apparatus when the packing member is received in the cooking apparatus or at least a portion of an outlet formed to allow air in the cooking apparatus to be discharged.
