Solution Overview

Problem

Blender containers with vacuum sealing mechanisms leak in high vibration environments, such as vehicles or when carried in bags, due to the failure of seals to retain liquids and ingredients effectively.

Innovation Solution

A container assembly with a needle valve and umbrella valve system, coupled with a biasing mechanism, that forms and breaks a vacuum within the blender container to prevent leakage, utilizing a coil spring and vacuum pad for sealing engagement and movement control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a seal is used to form a vacuum within the blender container, then nutritional degradation is reduced, but liquid leakage occurs in high vibration environments

Engineering Contradiction:
Improvevacuum sealing reliabilityVSAvoidliquid leakage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The needle valve is designed to be movable rather than fixed, allowing it to dynamically adjust its position in response to vibration forces. The biasing mechanism enables the valve to move between open and closed positions, maintaining sealing reliability under varying vibration conditions that would cause a fixed seal to fail.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational state of the valve from a static closed position to a dynamically controllable open/closed state. By introducing the movable needle valve with biasing mechanism, the system can adjust the sealing parameter in real-time to maintain vacuum integrity during vibration while preventing liquid leakage.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a movable needle valve is used to control vacuum formation, then vacuum sealing is improved, but device complexity increases

Engineering Contradiction:
Improvevacuum sealing reliabilityVSAvoidvalve mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The biasing mechanism provides self-actuating functionality, where the spring automatically returns the needle valve to its closed position after vacuum formation. This eliminates the need for complex control systems, motors, or electronic actuators, maintaining simplicity while achieving reliable vacuum sealing.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The biasing mechanism acts as an intermediary between the needle valve and the vacuum chamber, providing the necessary force to maintain sealing without requiring direct complex control. The spring mechanism mediates the interaction between vacuum pressure and valve position, simplifying the overall control architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)
