Solution Overview

Problem

Existing oven support devices require a large interior space for rotary movement, limiting their compactness and efficiency in moving support elements in and out of the oven.

Innovation Solution

A pivoting element with two rotatable arms and three pivot axes allows for horizontal movement of a support element, enabling it to be completely moved into or out of the oven's cavity, designed for use in various furniture types and materials, including ovens, with damping and height adjustment features for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single pivot arm with rotary movement is used to move a support element out of the oven, then the support element can be rotated out horizontally, but a large interior space is required for the rotational movement

Engineering Contradiction:
Improvehorizontal rotary movement of support elementVSAvoidinterior space of oven
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The single pivot arm is divided into two separate pivot arms (first pivot arm and second pivot arm) that work in sequence. The first pivot arm rotates the support element partially, then the second pivot arm completes the rotation. This segmentation allows the same horizontal rotary movement function to be achieved with a more compact configuration that requires less interior oven space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a second pivot axis that is arranged perpendicular to the first pivot axis. This adds a dimensional aspect to the movement mechanism, allowing the support element to be moved out through a combination of rotations around two perpendicular axes rather than a single large-radius rotation, thereby reducing the space required within the oven interior.

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

2Volume of stationary object

If a two-armed pivoting device with three pivot axes is used to move support element completely in and out, then space efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveinterior space of ovenVSAvoidpivoting device structure
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The two pivot arms are merged into a single integrated pivoting device structure that shares common components and mounting points. The first and second pivot arms are coupled together such that they operate as a coordinated unit, reducing the overall number of separate components and simplifying the device structure despite the addition of a second pivot axis.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pivoting device is designed to perform multiple functions: it can move the support element completely in and out horizontally, it can also rotate the support element, and it maintains stability during these movements. The same two-armed structure with three pivot axes handles both the retraction/exterior movement and the rotational positioning, making the device multi-functional and justifying its complexity through versatile operation.

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

AI summary

Device for attaching a support element for objects in a body, in particular a device for attaching a food support in an oven, the device having a pivoting element for arranging the support element and attachment means, the pivoting element in the body being able to be attached to a wall section of the body with the attachment means . The device is characterized in that the pivoting element comprises two pivoting arms which are rotatable relative to one another, with the pivoting element having three pivoting axes, with a first pivoting arm being arranged on the body such that it can rotate through a first pivoting axis in the mounted state on the body, the two pivoting arms are arranged rotatably on one another via a second pivot axis, with a third pivot axis being present on a second pivot arm, with the carrier element being rotatable by the third pivot axis in relation to the second pivot arm in the region of one end of the second pivot arm, and with the pivoting element being in the arranged state on the body during a pivoting and/or sliding movement of the pivoting element, a carrier element arranged on it can be moved in a single, exclusively horizontal plane of movement, whereby the carrier element arranged on the pivoting element can be moved into or out of the body.
