Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment machines require significant time for detergent flow path assembly and are prone to water leakage due to internal pressure changes, leading to user confusion about detergent storage part or flow path damage.
Innovation Solution
A laundry treating apparatus with a detergent flow path featuring a water trap and decelerating walls to minimize water discharge into the tub during pressure changes, guiding water to the cabinet entrance and preventing external confirmation of water flow from the trap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trap is provided in the detergent flow path to interrupt connection between tub and detergent storage part, then foam discharge into detergent storage part is prevented, but water stored in trap is discharged into tub when door opens causing user confusion
Solution Approach 1:
The harmful effect of water discharge from the trap is extracted and separated from the main detergent flow path. The trap is positioned and configured so that any water discharged from it flows directly into the cabinet interior through the gap between the detergent storage part and cabinet wall, rather than into the tub. This extracts the harmful water discharge effect from the functional water flow path.
Solution Approach 2:
The gap space between the detergent storage part and cabinet wall acts as an intermediary channel. Water discharged from the trap flows through this intermediary space into the cabinet interior, preventing direct discharge into the tub. This intermediary path redirects the harmful effect away from the tub while maintaining the trap's foam interruption function.
2Reliability
If detergent flow path is fixed through clamp to detergent storage part and tub, then connection is secure, but assembly time is considerable
Solution Approach 1:
Multiple connection functions are merged into integrated connection structures. The detergent storage part and tub are designed with built-in connection features that combine securing and positioning functions, eliminating the need for separate clamp components and reducing assembly steps while maintaining secure connection.
Solution Approach 2:
The detergent storage part and tub are designed with self-aligning and self-securing features. The connection structures automatically position and secure the detergent flow path without requiring additional fastening operations, enabling quick assembly while ensuring reliable connection.
3Stability of the object's composition
If water flows from trap to insulating part during pressure change, then pressure equalization occurs, but water flow is externally confirmed causing user doubt about damage
Solution Approach 1:
The water discharge phenomenon is extracted from the visible operational path and redirected to an invisible path. Water flowing from the trap during pressure changes is directed into the cabinet interior through the gap, making it invisible to users. This extracts the harmful visual confirmation of water flow from the user-facing operational area.
Solution Approach 2:
The cabinet interior space acts as an intermediary that receives and conceals water flow from the trap. By routing water through this intermediary space rather than allowing it to flow visible paths, the system maintains pressure equalization functionality while preventing user observation of the water flow that would suggest damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple assembly of the detergent flow path, prevents leakage, minimizes water discharge due to internal pressure changes, and conceals water flow from the trap, reducing user confusion about potential damage.
Implementation Method 1
a decelerating part provided to the insulating part connecting pipe to decelerate a flow speed of water moving from the trap forming pipe to the insulating part connecting pipe
Implementation Method 2
a trap forming pipe forming one of a P-trap, a U-trap and an S-trap between the storage part connecting pipe and the insulating part connecting pipe
Implementation Method 3
