Folded Packing Insert for Stabilizing Large Washer Outer Tubs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing materials for laundry treatment apparatuses are inadequate for large-size washing machines with an outer tub opening diameter larger than the entrance/exit hole diameter, leading to instability during delivery.
Innovation Solution
A plate-type packing material with a base part and a gap compensating part, where the base part is inserted between the outer tub and the entrance/exit hole forming part, and the gap compensating part is inserted into the outer tub, allowing for secure fixation and preventing shaking during delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the outer tub opening diameter is increased to accommodate larger laundry capacity, then the washing machine capacity is improved, but the outer tub becomes unstable and shakes during delivery
Solution Approach 1:
The packing material is inserted into the space between the outer tub and the entrance/exit hole forming part, nesting the packing material within the existing structural gaps to provide stabilization without adding external components
Solution Approach 2:
The packing material acts as an intermediary element between the outer tub and the entrance/exit hole forming part, filling the gap and preventing relative movement while maintaining the increased outer tub diameter for larger capacity
2Ease of manufacture
If conventional packing materials are used for large-size washing machines with outer tub opening larger than entrance/exit hole, then manufacturing simplicity is maintained, but the packing material cannot prevent shaking during delivery
Solution Approach 1:
The packing material serves as an intermediary component that fills the gap between the outer tub and entrance/exit hole forming part, enabling conventional easy-to-install packing methods to work effectively for large-size washing machines by providing the missing structural support
Solution Approach 2:
The packing material is specifically positioned in the gap between the outer tub and entrance/exit hole forming part, providing localized stabilization exactly where needed rather than requiring complete restructuring of the packing system

AI summary
The present invention relates to a packing material for a laundry treatment apparatus having a casing with an entrance/exit hole through which laundry is entered and exited and an outer tub hung in the casing and having an opening through which the laundry is entered and exited, the packing material including a base part at a side of a predetermined fold line corresponding to the shape of the opening and a gap compensating part at another side of the fold line, wherein the base part is inserted into a space between the outer tub and an entrance/exit hole forming part forming the entrance/exit hole in the casing, and wherein the gap compensating part is inserted into an inside of the outer tub when the packing material is folded along the fold line.
