Carrier Element Pivoting Mechanism for Space-Saving Horizontal Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for fitting carrier elements in bodies, such as ovens, require a large compartment interior area for rotary movement, limiting space efficiency.
Innovation Solution
The apparatus employs a pivoting member with two rotatable pivot arms and three pivot axles, allowing the carrier element to move exclusively in a horizontal plane, enabling it to be fully removed from and inserted into the body's cavity in a space-saving manner, with damping means to control movement and synchronization units for coordinated movement of multiple pivoting members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single pivot arm with rotary movement is used to move a carrier element out of the body, then the carrier element can be rotated out of the compartment, but a large compartment interior area is required for the rotary movement
Solution Approach 1:
The single rotary movement is segmented into two sequential pivoting movements. The carrier element is first pivoted horizontally along a first pivot axle, then pivoted vertically along a second pivot axle. This segmentation allows the carrier element to be removed from a compact space without requiring a large single-plane rotary movement area.
Solution Approach 2:
The movement is transitioned from a single horizontal plane to a two-dimensional path involving both horizontal and vertical pivoting axes. By adding the vertical dimension through the second pivot axle, the system achieves complete removal capability while using less horizontal compartment space.
2Area of stationary object
If a pivoting member with two pivot arms and three pivot axles is used to enable complete removal of the carrier element, then space efficiency is improved, but the device complexity increases
Solution Approach 1:
The pivoting member with two pivot arms and three pivot axles serves multiple functions: it enables complete carrier element removal, provides stable mounting on the body wall portion, and allows controlled movement through damping means. This multi-functional design justifies the increased structural complexity by delivering superior space efficiency and operational capability.
3Reliability
If damping means are added to control the pivoting movement, then abrupt movement is prevented, but the device complexity increases
Solution Approach 1:
Damping means are incorporated into the pivoting member to provide beforehand cushioning during the pivoting movement. This prevents abrupt movement and ensures controlled, safe operation of the carrier element removal mechanism, justifying the additional complexity through improved reliability and user safety.

AI summary
An apparatus for fitting a carrier element in a body, including a pivoting member for arranging the carrier element, and fitting means for fitting the pivoting member on a wall of the body. The pivoting member includes two rotatable pivot arms and has three pivot axles. When mounted on the body, a first pivot arm is arranged on the body in a rotatable manner by way of a first pivot axle, the two pivot arms are arranged in a rotatable manner on one another via a second pivot axle, and a third pivot axle is provided on a second pivot arm. Near one end of the second pivot arm, the carrier element is rotatably arranged with respect to the second pivot arm by the third pivot axle, and, during a pivoting and/or displacement movement of the pivoting, a carrier element arranged thereon is movable in a single, exclusively horizontal plane.
