Solution Overview

Problem

Existing food processing systems lack a configuration that allows for a streamlined flow of fluids through a closable lid opening while ensuring gas closure and preventing unintentional spills, particularly during culinary preparations that require slow fluid supply rates.

Innovation Solution

A food processing system with a spout-like recipient and a lid featuring a single closable opening and flow guiding means, including a wall part and flow passage sections that facilitate streamlined fluid flow under gravity, along with a closing element that can be retained in the lid opening to prevent spills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single lid opening is provided without flow guiding means, then the lid structure is simple, but the fluid flow pattern is bulk and uncontrolled leading to potential spills

Engineering Contradiction:
Improvelid structureVSAvoidfluid flow control
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The lid opening is segmented into multiple functional zones: a main opening for pouring and a secondary opening for controlled fluid return. Flow guiding means are divided into multiple elements including a spout, a flow guide wall, and a collection channel. This segmentation allows independent control of different fluid flow paths, enabling streamlined flow while maintaining simple overall lid structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Flow guiding means act as an intermediary element between the main opening and the recipient interior. The flow guide wall and collection channel serve as intermediate structures that capture, redirect, and control fluid flow, preventing direct bulk pouring into the recipient and enabling controlled streamlined flow instead.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a secondary opening is added for streamlined flow control, then fluid flow control improves, but the lid structure becomes more complex

Engineering Contradiction:
Improvefluid flow controlVSAvoidlid structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flow guiding means are merged with the lid structure itself rather than being separate components. The flow guide wall extends from the lid rim, and the collection channel is integrated into the lid body, combining multiple functions (flow guidance, fluid collection, and return) into a single integrated structure that reduces overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flow guiding means serve multiple functions simultaneously: guiding fluid flow from the main opening, collecting errant drips, providing a return path for controlled fluid addition, and preventing spills. This multi-functionality reduces the need for separate components, maintaining simple lid structure while achieving reliable fluid flow control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If flow guiding means are provided for streamlined flow, then culinary precision improves, but the risk of unintentional spills increases without proper closure mechanism

Engineering Contradiction:
Improveculinary precisionVSAvoidspill hazard
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The lid opening configuration allows dynamic control of fluid flow paths. The flow guide wall and collection channel can accommodate different pouring rates and angles, adapting to various culinary operations. The closing element can be positioned to allow either streamlined flow through the secondary opening or complete closure to prevent spills, providing dynamic response to operational needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collection channel acts as an intermediary safety mechanism that captures any fluid that escapes the streamlined flow path through the secondary opening. This intermediate collection structure prevents direct spills onto the cooking surface, mitigating the spill hazard while maintaining culinary precision through controlled flow.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If a closing element is added to the lid opening, then gas closure and spill prevention improve, but the device complexity increases

Engineering Contradiction:
Improvegas closureVSAvoidlid structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closing element is designed as a removable component that can be taken out when not needed (e.g., during steam venting operations) and inserted when gas closure is required. This extractable design provides gas closure functionality without permanently increasing lid structure complexity, allowing the lid to maintain simplicity while achieving reliable closure when needed.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The closing element is designed to self-align and self-retain in the lid opening through complementary geometric features. The closing element's shape matches the lid opening geometry, allowing it to be easily positioned and retained without complex locking mechanisms, providing gas closure while minimizing added complexity.

Inventive Principle:
Principle #25Self-service
