Ring-Shaped Filter Plate for Solid-Liquid Separation in Pitchers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pitchers do not effectively separate solids from liquids during pouring, leading to inconvenience and potential choking hazards.
Innovation Solution
A pitcher design featuring a ring-shaped filter plate positioned below the pouring opening, which separates solids from liquids by allowing liquid to pass through while blocking solids, integrated with a cover unit and insert member for cooling and easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pitcher without filter is used, then the structure is simple, but solids are poured out together with liquid causing inconvenience
Solution Approach 1:
The pitcher is segmented into functional zones: the filter plate separates the pouring path from the bulk liquid, allowing solids to be retained while liquid passes through. The cover member with insert member creates a separate cooling zone. This segmentation enables independent optimization of each function without excessive complexity.
Solution Approach 2:
The filter plate acts as an intermediary element between the receiving space and the pouring opening. It mediates the flow by allowing liquid to pass through while blocking solids, thus solving the problem of solids being poured out without requiring a completely complex filtration system.
2Loss of time
If manual removal of solids is required, then the pitcher structure is simple, but time is lost and choking hazard exists
Solution Approach 1:
The filter plate is pre-positioned in the pitcher body at the pouring opening before use. This preliminary placement ensures that solids are automatically retained during pouring without requiring any subsequent manual intervention, thus eliminating time loss and choking hazards while maintaining structural simplicity.
Solution Approach 2:
The filter plate enables the pitcher to serve itself by automatically separating solids from liquid during the pouring process. No external intervention or additional steps are required - the filtration function is self-executing as liquid flows through the filter plate, saving time and eliminating safety concerns.
3Temperature
If cooling rod is placed in refrigerator in advance, then cooling effect is achieved, but the pitcher cannot filter solids simultaneously
Solution Approach 1:
The cooling function and filtration function are merged into a single integrated system. The insert member with cooling rod and the filter plate work together in the same pitcher structure, allowing both cooling and solid-liquid separation to occur simultaneously during the pouring process, eliminating the need for separate operations.
Solution Approach 2:
The pitcher is designed with multi-functionality: the same structure serves both cooling purposes (via the insert member with cooling rod) and filtration purposes (via the filter plate). This universal design allows the pitcher to perform multiple functions - cooling, filtering, and pouring - without requiring separate devices or sequential operations.
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
Effectively prevents solids from being poured with the liquid, enhancing convenience and safety by automatically retaining solids within the pitcher, thus eliminating the need for manual removal.
Implementation Method 1
The filter plate is ring-shaped, is disposed in the receiving space at a position below the pouring opening of the pitcher body, is sleeved on one of a bottom portion of the cover member and a top portion of the insert member, and is adapted for filtering out the solids during passage of the liquid therethrough

AI summary
A container is adapted to contain a liquid and separate solids from the liquid. The container includes a body, a cover unit, and a ring-shaped filter plate. The body defines a receiving space adapted for receiving the liquid therein, and has a top opening and a pouring opening in spatial communication with the receiving space. The cover unit includes a cover member removably covering the top opening, and an insert member extending downwardly from the cover member into the receiving space. The filter plate is disposed in the receiving space at a position below the pouring opening, is sleeved on one of a bottom portion of the cover member and a top portion of the insert member, and is adapted for filtering out the solids during passage of the liquid therethrough.
