Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household appliance packaging devices do not provide adequate protection during transport, especially for appliances of varying masses, and fail to comply with regulatory standards for impact and vibration absorption.
Innovation Solution
A packaging unit with multiple support dampers, including first, second, and third support dampers, designed to absorb impacts and vibrations, where the first support damper deforms initially, followed by the second and third, providing irreversible deformation for successive impacts, and made predominantly of polystyrene for lightness and cost-effectiveness, ensuring a high level of protection and compliance with regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple support dampers are used to improve impact absorption, then protection level increases, but device complexity increases
Solution Approach 1:
The packaging unit is divided into multiple support dampers arranged in series (first, second, and third support dampers), each capable of independent deformation. This segmentation allows the system to absorb impacts through multiple stages, improving protection while maintaining manageable complexity through modular design
Solution Approach 2:
The support dampers are pre-positioned in a ready state to absorb impacts before they reach the household appliance. The first support damper is positioned to absorb initial impacts, with subsequent dampers providing additional cushioning layers, ensuring protection is activated in advance of any harmful forces reaching the appliance
2Reliability
If support dampers are designed for irreversible deformation to protect against successive impacts, then reliability improves, but manufacturing precision requirements increase
Solution Approach 1:
The support dampers are designed to undergo permanent deformation as their protective mechanism. By changing the physical state from elastic to plastic deformation, the dampers provide reliable protection against successive impacts. The series arrangement ensures that as one damper deforms, others remain available to absorb additional energy
Solution Approach 2:
The support dampers are designed as sacrificial elements that are depleted after use. Once a damper has deformed and absorbed impact energy, it is considered used up and cannot be reused for the same level of protection. This approach prioritizes reliable protection over component reusability
3Ease of manufacture
If packaging unit is made predominantly of polystyrene to reduce weight and cost, then ease of manufacture improves, but strength decreases
Solution Approach 1:
The support dampers are constructed from polystyrene foam material with a porous cellular structure. This porous material provides excellent energy absorption capabilities through cell collapse mechanisms, delivering high protection performance while maintaining low density and ease of manufacture. The foam structure allows the material to be both lightweight and effectively strong for impact absorption
Solution Approach 2:
The packaging unit employs polystyrene foam as a composite material solution that combines lightweight properties with impact absorption capabilities. The foam structure creates a material that is easier to manufacture than solid plastics while providing sufficient strength through its cellular architecture and deformation mechanisms

Function Achieved in This Case
The solution effectively absorbs impacts and vibrations, providing enhanced protection for household appliances during transport, ensuring compliance with legal standards and maintaining appliance orientation, even if some support dampers are compromised, through a progressive deformation mechanism and use of polystyrene for reduced weight and cost.
Implementation Method 1
The first support damper and the second support damper are each intended to be at least partially irreversibly deformed during at least one damping process
Implementation Method 2
a support damper which is intended to absorb an impact acting on the packaging unit, in particular an impact triggered by a fall of the packaging unit, and/or a vibration affecting the packaging unit

AI summary
The invention relates to a household appliance packaging device with at least one packaging unit (10) for at least partially securing a household appliance. To provide a generic household appliance packaging device with advantageously high protection of the appliance, it is proposed that the packaging unit (10) comprises at least one first support damper (14a-I) and at least one second support damper (16a-m) downstream of the first support damper (14a-I).
