Solution Overview

Problem

Existing toasters inconvenience users when spreading jam on bread slices due to the vertical placement of bread, leading to potential jam dripping and contamination.

Innovation Solution

A toaster design featuring a combination of vertical and horizontal toasting chambers, allowing for simultaneous jam spreading and toasting without the risk of jam dripping, achieved through a rotatable upper cover and lower plate configuration that enables horizontal toasting, reducing the toaster's size and component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bread slices are vertically placed in the toasting chamber, then the toasting process is efficient, but it is inconvenient for spreading jam and jam may drip causing contamination

Engineering Contradiction:
Improveconvenience of jam spreadingVSAvoidjam dripping contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent divides the toasting chamber into two separate chambers: a first toasting chamber for vertical toasting and a second toasting chamber for horizontal toasting. This segmentation allows users to choose the horizontal chamber when spreading jam, eliminating the contamination problem while maintaining the efficiency of vertical toasting for regular use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension by adding the second toasting chamber that extends in the horizontal direction, perpendicular to the first chamber's vertical orientation. This dimensional change provides a new toasting configuration that accommodates jam spreading activities without compromising toasting functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a single toasting chamber is used, then the device structure is simple, but it cannot accommodate both vertical and horizontal toasting functions

Engineering Contradiction:
Improvedual toasting functionalityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges two toasting chambers with different orientations (vertical and horizontal) into a single integrated device. The first and second toasting chambers share common structural elements and heating components, allowing the device to provide both vertical and horizontal toasting functions while controlling overall structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating pipes are designed to serve both toasting chambers universally. The same heating system can heat both the first vertical chamber and the second horizontal chamber, making the heating components multi-functional and reducing the need for separate heating systems for each chamber.

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

3Reliability

If separate heating systems are used for vertical and horizontal toasting, then each function works independently, but the device size and manufacturing cost increase

Engineering Contradiction:
Improveindependent heating reliabilityVSAvoidtoaster size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The heating pipes are designed as universal components that can heat both the first vertical toasting chamber and the second horizontal toasting chamber. This multi-functional heating system eliminates the need for separate heating systems, reducing device size and manufacturing cost while maintaining reliable heating performance for both toasting orientations.

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