Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted drum type washing machines lack separate detergent and conditioner boxes, leading to user difficulties in adding these correctly, which can result in improper timing and malfunctions during washing operations.
Innovation Solution
A wall-mounted drum type washing machine design that includes detachable detergent and conditioner boxes with specific insertion holes and handles, featuring a misassembling prevention unit to ensure correct placement and prevent washing operations when boxes are incorrectly assembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate detergent box and conditioner box are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The detergent box and conditioner box are nested within the washing machine tub, with each box inserted through the front panel into the tub interior. This nesting approach allows separate detergent and conditioner storage without adding external structural complexity, as the boxes utilize the existing tub space.
Solution Approach 2:
The front panel serves multiple functions: it acts as the door closure, provides insertion holes for both detergent and conditioner boxes, and houses the misassembling prevention unit. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
2Reliability
If misassembling prevention unit is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The misassembling prevention unit employs asymmetric positioning of protrusions and recesses on the detergent box and conditioner box handles. The first handle has a protrusion that fits into a specific recess position, while the second handle has a differently positioned protrusion. This asymmetric design ensures that each box can only be correctly assembled in its designated location, providing reliable prevention of misassembly without requiring complex electronic or mechanical locking systems.
3Ease of operation
If detergent box and conditioner box are inserted into tub, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The misassembling prevention unit provides localized guidance and positioning features at the insertion points. The protrusions and recesses are precisely positioned only where needed for correct box placement, rather than requiring high precision throughout the entire front panel. This localized approach to precision reduces overall manufacturing requirements while ensuring correct assembly at critical points.
