Draining Rack with Rotatable Squeezing Mechanism for Cleaning Sponge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing draining racks for cleaning sponges require a predetermined draining time to remove water, which can be prolonged due to the lack of a mechanism to expedite the drainage process.
Innovation Solution
A draining rack design featuring a fixed rack and a movable rack that can be rotated between upright and tilted positions, allowing the cleaning sponge to be squeezed and drained efficiently by interposing it between the two racks, thereby reducing drainage time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the cleaning sponge is mounted in the draining rack without squeezing, then the sponge can be drained passively, but the draining time becomes prolonged
Solution Approach 1:
The movable rack is designed to be rotatable between a horizontal position (for squeezing) and a vertical position (for draining). This dynamic transformation allows the same structure to perform multiple functions: actively squeezing the sponge to remove water quickly, then passively draining it by gravity when positioned vertically. The rotatable design resolves the contradiction by enabling active water removal when needed while maintaining operational simplicity.
2Productivity
If a movable rack is added to enable squeezing, then draining efficiency is improved, but device complexity increases
Solution Approach 1:
The squeezing function and draining function are merged into a single integrated system. The movable rack serves dual purposes: when rotated to the horizontal position, it acts as a pressing surface for squeezing the sponge; when rotated to the vertical position, it becomes part of the draining structure. This merging eliminates the need for separate squeezing and draining devices, improving productivity while controlling complexity through functional integration.
Solution Approach 2:
The movable rack is designed with multi-functionality, serving both as a squeezing mechanism and a draining support. By rotating between horizontal and vertical positions, the same component performs different functions in the draining process. This universal design improves draining efficiency without requiring multiple separate components, thus limiting the increase in device complexity.
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
The design significantly reduces the time required for draining the cleaning sponge by enabling effective squeezing and drainage without manual effort, providing improved convenience and protection from sterilization agents.
Implementation Method 1
The movable rack is supported by the fixed rack such that the movable rack can be rotated between an upright position at which the movable rack stands upright on the front side of the fixed rack and a tilted position at which the movable rack is tilted toward the front side from the upright position

AI summary
A draining rack is configured including a fixed rack and a movable rack supported such that it can be tilted with respect to the fixed rack. The movable rack is supported by the fixed rack such that it can be tilted (rotated) between an upright position at which it stands upright on the front side of the fixed rack and a tilted position at which it is tilted from the upright position. By rotating the movable rack from the tilted position to the upright position in a state in which a cleaning sponge is held (interposed) between the fixed rack and the movable rack, this arrangement is capable of squeezing the cleaning sponge. This allows the draining time for the cleaning sponge to be reduced.
