Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High temperatures within cooking compartments of white goods, such as ovens, can damage control panel components and pose risks to users and surrounding objects when the door is opened, as hot air and gases escape, and existing solutions complicate manufacturing and do not adequately address component protection during cooking.
Innovation Solution
A white good design featuring a fan that directs cooler outer environment air through a channel to the control panel, combined with a flap arrangement that adjusts to create an air curtain when the door is opened, preventing hot air and gases from escaping and protecting components and users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fan is used to cool control panel components by circulating outer environment air through a channel, then control panel components are protected from high temperature damage, but hot air and gases escape when the door is opened, negatively affecting users and surrounding objects
Solution Approach 1:
The patent introduces a flap arrangement as an intermediary element between the compartment interior and exterior. This flap acts as a mediator that selectively controls air flow: allowing cooling air to pass through the channel to protect components while blocking hot air and gases from escaping when the door is opened, thus protecting both components and users from harmful thermal effects
Solution Approach 2:
The flap arrangement is designed to be dynamic rather than static, automatically adjusting its position based on door state. When the door is closed, the flap allows air flow for component cooling; when the door opens, the flap moves to block the channel, preventing hot air escape. This dynamic adaptation resolves the contradiction by changing the system's behavior based on operational conditions
2Object-affected harmful factors
If existing air curtain solutions are implemented by blowing air through side walls with multiple modifications, then users are protected from hot air, but manufacturing process is complicated and manufacturing costs increase
Solution Approach 1:
The flap arrangement serves multiple functions within a single structural element: it acts as a flow control valve for the cooling channel, forms an air curtain at the door opening, and provides thermal insulation. This multi-functionality eliminates the need for separate air curtain generation systems, simplifying manufacturing while effectively protecting users from hot air
Solution Approach 2:
The patent combines the air curtain function with the existing cooling channel structure by integrating the flap arrangement into the channel. Instead of adding separate air curtain generation components to side walls, the cooling channel itself is adapted to serve dual purposes: component cooling and user protection, reducing manufacturing complexity
3Object-affected harmful factors
If existing solutions focus on protecting users from hot air, then user safety is improved, but control panel components during cooking process remain vulnerable to high temperature damage
Solution Approach 1:
The flap arrangement is positioned and configured to act in advance before hot air can escape and damage components or affect users. When the door begins to open, the flap proactively blocks the cooling channel, preventing hot air from entering the control panel area. This preliminary action protects both users and components simultaneously
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 cools control panel components, prevents damage from high temperatures, and creates a safe air curtain that reduces the impact of hot air and gases on users and objects, while being cost-effective and easy to produce.
Implementation Method 1
a channel, at least one part of which opens into the cavity, which has at least one inlet opening at at least another part, and which is provided at the body so as to be in thermal connection with the control panel
Implementation Method 2
at least one fan which is provided at the body, which draws, through at least one hole provided on the body, the outer environment air having a temperature lower than the temperature within the compartment, which directs this drawn air into the channel through the inlet opening
Implementation Method 3
a flap arrangement which comprises: at least one first hinge; at least one first flap which has a plate structure extending parallel to the first side, which is in connection with the first hinge so as to be able to move by rotating around an axis, which has a first position that allows the air, reaching to the cavity through the channel, to pass to the outer environment when the door is in the closed position, and a second position that enables the air reaching to the cavity to be directed towards the opening by posing an obstacle to the connection of the cavity with the outer environment when the door is opened
