Steamer Attachment Handle Shield Design to Reduce Steam Burn Risk

Solution Overview

Problem

Current steamer attachments for food processors do not adequately simplify or ensure safety during steam cooking, as they lack effective protection against hot steam, requiring users to use additional protective measures like gloves or potholders.

Innovation Solution

A steamer attachment comprising a steamer bowl, an intermediate tray with handles and handle shields, and a lid with handle plates, allowing for safe handling and steam penetration, which can be stacked and used with or without an intermediate tray, featuring steam inlets and perforated bases for efficient steam distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users handle the intermediate shell during steam cooking, then handling and repositioning is enabled, but risk of burns from hot steam increases

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A steam-deflecting shell is introduced as an intermediary element between the hot steam environment and the user's hand. This shell extends beyond the intermediate shell and is designed to deflect steam away from the handling area, allowing users to safely grip and reposition the intermediate shell without direct exposure to harmful steam

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The steam-deflecting shell provides preliminary protection by preemptively blocking and redirecting steam flow before it can reach the user's hand. The shell's extended structure creates a protective barrier that anticipates and prevents the harmful effect of steam contact during handling operations

Inventive Principle:
Principle #9Preliminary anti-action

2Volume of moving object

If the steamer attachment uses a compact stacked design, then space efficiency is improved, but accessibility of handles may be reduced

Engineering Contradiction:
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The steam-deflecting shell is designed as a movable or adjustable element that can be positioned to provide steam protection while maintaining handle accessibility. The dynamic configuration allows the shell to adapt between protecting the handles during storage/transport and not interfering with handle access during operation

Inventive Principle:
Principle #15Dynamics

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 enhances safety by reducing the risk of burns from hot steam and simplifies handling, eliminating the need for protective gear, while maintaining efficient steam cooking and a compact design.

Implementation Method 1

the steam generated in the vessel when they are used can enter the steamer bowl or (directly or through the steamer bowl) into the intermediate bowl

Methodology Applied
Scientific EffectSteam generation and flow: Evaporation

Implementation Method 2

Food placed in the container can then be cooked in the rising steam

Methodology Applied
Scientific EffectHeat transfer through steam: Convection
