Solution Overview
Problem
Conventional household appliances, such as dishwashers, face damage during storage and transport due to external clamping forces, which are not introduced efficiently without additional complex components for force absorption.
Innovation Solution
A packaging element with a force transmission area directly contacts the supporting structural part, eliminating the need for additional force-absorbing components and allowing for simple and cost-effective introduction of clamping forces, featuring a positioning aid for precise placement and increased material rigidity in the force transmission area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional force-absorbing elements are arranged between the packaging element and the load-bearing structural component, then the appliance is protected from damage during transport, but the device complexity and number of components increase
Solution Approach 1:
The packaging element is merged with the force transmission function by integrating a force transmission area directly into the packaging element itself. This eliminates the need for separate force-absorbing elements, as the packaging element directly transmits clamping forces to the load-bearing structural component (such as the support frame or hinge support) during transport and storage.
Solution Approach 2:
The force transmission function is extracted from the packaging element and directly applied to the load-bearing structural component. By removing intermediate housing side walls or cladding elements between the packaging element and the structural component, the force transmission path is simplified and made more direct, reducing the number of components involved.
2Stability of the object's composition
If housing side walls are used to enclose the appliance, then the appliance structure is complete, but the force transmission path becomes complex and additional components are required
Solution Approach 1:
The housing side walls or cladding elements are removed or excluded from the force transmission path. The packaging element is positioned to contact the load-bearing structural component directly, bypassing the need for force transmission through housing side walls. This extraction simplifies the force transmission path while maintaining structural completeness for the appliance's operational state.
Solution Approach 2:
The appliance structure is segmented into distinct functional zones: the load-bearing structural component (support frame, hinge support) that handles force transmission, and the housing elements that provide operational enclosure but are excluded from the force transmission path during packaging. This segmentation allows independent optimization of each zone's function.
3Reliability
If force-absorbing elements are mounted in an additional assembly step, then the appliance receives adequate protection, but the assembly time and manufacturing complexity increase
Solution Approach 1:
The force transmission area is merged into the packaging element design, allowing the packaging element to be manufactured as a single integrated component with its force transmission function built-in. This eliminates the need for separate assembly steps to mount force-absorbing elements, as the packaging element is applied to the appliance in its final form, ready to transmit forces immediately.
Solution Approach 2:
The force transmission capability is prepared in advance during the packaging element manufacturing process, not during appliance assembly. The packaging element is pre-configured with the appropriate geometry and material properties to transmit clamping forces directly to the load-bearing structural component, eliminating the need for additional assembly operations.

AI summary
The household appliance has packaging elements (15-18) that are provided at the side surfaces of main portion, so as to cover the preset regions of main portion. The structural elements (1,5,7,9) are provided at the uncovered regions of the main portion. Each packaging element is comprised of force transmission area with force application region (21) which acts as bearing surface for structural element.
