Solution Overview

Problem

Cooling appliances lack specialized storage containers for grains and legumes, leading to issues like reduced usage volume, metabolic activity-related water vapor condensation, and accidental grain flow due to lack of a locking mechanism in existing grain dispensing units.

Innovation Solution

A grain dispensing unit with a locking mechanism is integrated into the cooling appliance, featuring a pivotable dispenser with a chute that can be locked to prevent accidental activation, allowing for controlled grain flow and independent operation from the dispenser lever to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a grain dispensing unit is provided in the cooling appliance, then grain storage convenience is improved, but accidental grain flow occurs due to lack of locking mechanism

Engineering Contradiction:
Improvegrain storage convenienceVSAvoidaccidental grain flow prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The locking mechanism is designed to proactively prevent accidental grain flow by blocking the chute before unintended activation can occur. The lockable state serves as a preliminary protective measure that counteracts the potential harmful effect of accidental dispenser activation, allowing users to secure the grain dispensing unit when grain flow is not desired.

Inventive Principle:
Principle #9Preliminary anti-action

2Reliability

If the locking mechanism is connected to the dispenser lever, then grain flow control is improved, but breakage of locking mechanism parts occurs due to force applied by user

Engineering Contradiction:
Improvegrain flow controlVSAvoidlocking mechanism durability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The locking mechanism is segmented into an independent unit separate from the dispenser lever mechanism. This segmentation allows the locking function to operate independently without being subjected to the forces applied during normal dispenser operation. Users can lock or unlock the grain dispensing unit without applying force to the dispenser lever, eliminating the risk of breakage while maintaining grain flow control capability.

Inventive Principle:
Principle #1Segmentation

3Reliability

If hermetically sealed containers are used for grain storage, then shelf life is improved, but water vapor condensation occurs inside the container

Engineering Contradiction:
Improveshelf life extensionVSAvoidwater vapor condensation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The grain dispensing unit employs a non-hermetically sealed container design that allows controlled exchange of air between the stored grain and the external environment. This flexible sealing approach prevents water vapor accumulation and condensation inside the container while still providing sufficient protection against contamination. The controlled permeability maintains grain quality and extends shelf life without creating the condensation problem associated with completely sealed containers.

Inventive Principle:
Principle #30Flexible shells and thin films

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 locking mechanism prevents accidental grain flow and breakage, ensuring safe and controlled dispensing of grains, maintaining nutritional value and hygiene by allowing users to manage grain storage effectively within the appliance.

Implementation Method 1

A chute is provided on the dispenser and is configured to allow the grain to flow under the influence of gravity in the open position of the dispenser

Methodology Applied
Scientific EffectGravity: Gravitation
