Free Flow Valve Dispenser for Portion Control Without Food Crushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry food dispensers often crush large food pieces, experience food leakage, and fail to accurately control dispensed portions, leading to issues with freshness and quantity control.
Innovation Solution
A free-flow control dispenser with a turnable valve and adjustable angle mechanism, allowing users to control the portion size by adjusting the valve's opening angle and holding time, while preventing leakage through a position limiting system and a depressible handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional dispensing mechanism is used, then food can be dispensed, but large food pieces get crushed
Solution Approach 1:
The valve is made rotatable and adjustable, allowing dynamic control of the dispensing aperture size. Users can rotate the valve to different angles to match the size of food pieces, enabling large pieces to pass through without crushing while still allowing efficient dispensing of smaller pieces.
2Productivity
If the valve opening angle is increased to dispense larger portions, then dispensing speed increases, but food leakage occurs
Solution Approach 1:
The valve's rotatable design allows dynamic adjustment of the opening angle to precisely control the dispensing rate. Users can set appropriate angles based on desired portion sizes, maintaining reliable control while achieving faster dispensing when needed.
Solution Approach 2:
The valve opening angle is changed as a controllable parameter. By adjusting this parameter, users can optimize the balance between dispensing speed and leakage prevention for different food types and desired portion sizes.
3Measurement precision
If the dispensing mechanism is made more complex to control portion size accurately, then portion control precision improves, but device complexity increases
Solution Approach 1:
Portion control is achieved by changing a single parameter - the valve opening angle - rather than introducing complex mechanisms. Users rotate the valve to different angles to control portion size, providing accurate control through a simple, intuitive interface.
Solution Approach 2:
The valve design maintains structural simplicity and uniformity. The rotatable valve with wings follows the same basic design regardless of the opening angle, avoiding the need for different mechanisms for different portion sizes.
4Quantity of substance
If the valve is held open longer to dispense larger portions, then quantity dispensed increases, but food freshness is compromised
Solution Approach 1:
The rotatable valve allows users to pre-set the optimal opening angle for different portion sizes before dispensing. This enables precise control over dispensing duration and quantity, minimizing the time the food storage area is exposed and preserving freshness while still dispensing desired quantities.

AI summary
A dry food dispensing device for controlling the portion size of the dispensed food, comprising a storage receptacle for containing dry foods, wherein the receptacle is seated over a base providing a housing for a dispensing mechanism, the dispensing mechanism comprising:a turnable free flow valve having wings, capable of rotation to an opening angle defined by a position limiter; anda depressible handle for controlling the free flow valve via the position limiter,wherein the dispensing mechanism releases a portion of the dry food, with the portion being determined by a user as a function of time the turnable free flow valve is held at the opening angle.
