Salad Spinner Angled-Blade Fan for Faster Greens Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing salad spinner devices require multiple spins and manual intervention to effectively remove water from leafy greens due to centrifugal force pushing contents against perforated walls, obstructing water escape and increasing user effort and time.
Innovation Solution
A rotatable greens drying device with an integral air circulation mechanism and rotational forces, featuring a fan with angled blades that forces air through the colander to enhance drying by combining centrifugal force with airflow, allowing for faster moisture evaporation and reduced user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centrifugal force is used to remove water from greens, then water removal speed is improved, but contents are thrust outward against perforated walls obstructing water escape
Solution Approach 1:
The colander is divided into multiple sections with perforations distributed throughout, allowing water to escape from multiple locations simultaneously rather than being obstructed by a single perforated wall surface
Solution Approach 2:
The invention adds vertical airflow movement through the greens by positioning the fan above the colander, creating a third dimension of water removal (through evaporation and air flow) in addition to the horizontal centrifugal force, reducing the obstruction problem
2Productivity
If centrifugal force pushes contents against perforated walls, then water escape is enabled, but multiple spins and manual fluffing are required increasing time and effort
Solution Approach 1:
The fan provides continuous airflow through the greens during the spinning process, maintaining constant evaporation and water removal action throughout the drying cycle rather than requiring intermittent manual intervention
Solution Approach 2:
The system performs self-drying through the combination of centrifugal force and continuous fan airflow, eliminating the need for manual fluffing and multiple spinning cycles that require user intervention
3Productivity
If fan forces air through colander, then moisture evaporation is accelerated, but device complexity increases
Solution Approach 1:
The fan is integrated with the lid assembly, merging the air circulation function with the existing structural component rather than adding a separate, standalone fan unit to the colander
Solution Approach 2:
The lid assembly serves multiple functions: it provides structural support, houses the fan mechanism, and facilitates air circulation, thereby reducing overall device complexity through functional integration
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 device accelerates the drying process by using air circulation to expel water through the colander holes, reducing the need for multiple spins and manual fluffing, thus saving time and effort while maintaining a compact design for storage.
Implementation Method 1
A fan rotating with the colander forces air from outside and above the salad spinner into and through the colander and into the bottom of the salad spinner
Implementation Method 2
When a removable drive assembly is actuated, it rotates the colander creating the desired centrifugal force

AI summary
A salad spinner has a support frame with a receiving aperture. A colander is supported by the support frame in the receiving aperture for rotation about an axis of rotation. A removable drive assembly is removably coupled to the support frame and colander, and the removable drive assembly includes an actuator to transmit a driving input applied to the actuator to rotate the colander. A fan having a plurality of angled blades is mechanically coupled to the actuator to force air into the colander.
