Press Module with Horizontal-Axis Rotation to Prevent Double Wrinkles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses face issues with double wrinkles due to the pivoting mechanism of pressing plates parallel to the laundry's hanging direction, difficulty in applying maximum tensile force during fixation, and risk of component damage from uneven load distribution.
Innovation Solution
A press module with a pivotable cover and support system that applies tensile force through self-weight, uses a fixing member and tensile force applier to maintain laundry in an unfolded state before pressing, and employs a support system to prevent position change and component damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pivotable plate pivots about an axis parallel to the laundry's hanging direction, then the pressing mechanism is simple, but double wrinkles occur on the laundry
Solution Approach 1:
The patent inverts the conventional pressing approach by using a pivotable plate that pivots about an axis perpendicular to the laundry's hanging direction (horizontal axis) instead of parallel to it (vertical axis). This inversion changes the pressing sequence from top-to-bottom to side-to-side, ensuring that the entire width of the laundry is pressed simultaneously or in a sequence that prevents double wrinkles, while still maintaining mechanical simplicity
2Manufacturing precision
If the pivotable plate pivots about an axis parallel to the door's width direction, then double wrinkles are prevented, but the laundry position changes during pressing
Solution Approach 1:
The patent applies preliminary action by using a fixing member that secures the laundry to the pivotable plate before the pressing operation begins. This fixing member prevents the laundry from shifting or changing position during the pressing process, while the pivotable plate's horizontal-axis rotation ensures uniform pressing across the laundry width, eliminating double wrinkles
3Area of stationary object
If the laundry is pressed in an unfolded state, then the pressing area is large, but the component size and space requirement increase
Solution Approach 1:
The patent applies dynamics by enabling the pivotable plate to rotate about a horizontal axis, allowing the laundry to be pressed in a folded state. This dynamic mechanism maintains a large effective pressing area by folding the laundry during the pressing cycle, while keeping the press module compact and space-efficient. The folding action during pressing maximizes the contact area between the pressing plate and laundry without requiring a larger device
