Salad Spinner Brake Assembly With Caliper Ridge Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing salad spinners lack a braking system to stop the rotation of the basket, requiring users to wait for frictional forces to cease or manually open the device, which is inconvenient and can cause wear on the mechanical actuator and bearing surfaces.
Innovation Solution
A brake assembly is integrated into the cover of the salad spinner, featuring a caliper-like button structure that engages an annular upstanding ridge on the lid, allowing for controlled frictional engagement to stop or reduce the rotational movement of the basket, utilizing a guide channel and resilient materials for efficient braking and unbraking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no braking structure is provided, then the device structure remains simple, but the user must wait for frictional decay to stop the basket or manually open the cover, causing inconvenience and wear on mechanical components
Solution Approach 1:
The brake assembly is designed to be self-actuating through the user's natural interaction with the device. When the user presses the button on the cover, the caliper fingers automatically engage the ridge on the spinning basket to stop rotation. The system uses the user's pressing action to trigger the braking mechanism without requiring separate controls or complex actuation systems.
Solution Approach 2:
The braking function is extracted as a separate, dedicated component (brake assembly) rather than being integrated into the existing mechanical actuator or bearing surfaces. This allows the braking function to be implemented independently with optimized simplicity, using a button-actuated caliper structure that engages directly with the spinning basket ridge.
2Reliability
If frictional interaction between bearing surfaces is relied upon to stop the basket, then no additional braking components are needed, but the mechanical actuator and bearing surfaces experience increased wear
Solution Approach 1:
The braking function is extracted from the bearing surfaces and mechanical actuator, creating a dedicated brake assembly that handles the stopping function separately. This prevents the original mechanical components from experiencing excessive wear from braking operations, extending their lifespan and maintaining reliability.
Solution Approach 2:
The brake assembly acts as an intermediary between the user's stopping command and the spinning basket. The caliper fingers engage the ridge on the basket lid to create controlled friction for stopping, rather than relying on the bearing surfaces or mechanical actuator to provide braking through friction.
3Ease of operation
If the user manually opens the cover to stop the basket, then stopping can be achieved, but the device operation becomes inconvenient and may cause wear on the cover coupling mechanism
Solution Approach 1:
The brake assembly provides a self-service stopping mechanism that eliminates the need to open the cover. The button-actuated caliper fingers engage the spinning basket directly through the closed cover, allowing the user to stop rotation without disrupting the sealed configuration or wearing the cover coupling mechanism.
Solution Approach 2:
The brake assembly serves as an intermediary stopping mechanism that works through the closed cover configuration. The caliper fingers engage the ridge on the basket lid from the outside, providing a stopping function without requiring the cover to be opened or the coupling mechanism to be actuated.
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 brake assembly effectively and efficiently stops the basket's rotation, reducing wear on components and enhancing user convenience by allowing manual control over the spinning process without relying on frictional decay.
Implementation Method 1
two fingers of the structure move towards each other to clamp and frictionally engage an annular upstanding ridge on the lid, thereby reducing and/or stopping rotational movement of the basket

AI summary
A brake assembly for reducing the rotational velocity the spinning basket of a food spinning device applies a frictional force to an annular ridge on the lid of the spinning basket. A brake button movably disposed in a cover of the spinning device includes flexible pinching arms having cam surfaces. The cam surfaces of the flexible pinching arms extend through a guide aperture, thereby causing the pinching arms to flex toward each other when the brake button is depressed and to apply the frictional engagement to the annular ridge.
