Solution Overview

Problem

Existing container sealing systems for moving delicate equipment fail to provide a reliable and secure seal under various environmental conditions, particularly during transit via different vehicles, as they lack an efficient mechanism to ensure consistent compression of seals between the lid and base portions.

Innovation Solution

A sealing system featuring a rotatable latch coupled to a drive gear and a linkage assembly that includes pivotally coupled arms and a deformable tang, which, upon rotation, compresses a seal between the lid and base portions of the container, ensuring a secure seal through a cam assembly and guide channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple sealing mechanism is used, then the device complexity is reduced, but the reliability of the seal under varying environmental conditions deteriorates

Engineering Contradiction:
Improveseal reliabilityVSAvoidsealing mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing mechanism employs a dynamic linkage assembly with pivotally coupled arms that convert rotational motion into linear compression motion. The arms pivot about fixed pins and are guided by channels in the lid, allowing the seal to be consistently compressed along its length as the latch rotates, thereby maintaining reliable sealing under varying conditions without excessive complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The linkage assembly acts as an intermediary mechanism between the rotatable latch and the seal compression function. Through the pivotally coupled arms and guide channels, the rotational input is transformed into controlled linear compression of the seal, ensuring reliable sealing while distributing the mechanical action along the seal's length

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a complex sealing mechanism with multiple arms and linkages is used, then the seal compression consistency is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveseal compression consistencyVSAvoidlatch operation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The linkage assembly with pivotally coupled arms converts the simple rotational motion of the latch into effective linear compression of the seal. The dynamic pivoting action of the arms ensures consistent compression along the seal's length while requiring minimal operational force from the user, maintaining ease of operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cam assembly and guide channels work together to automatically guide the linkage arms through their pivot motion and ensure proper compression of the seal. The system self-regulates the compression force and path without requiring complex user input or adjustment, maintaining ease of operation while ensuring consistent sealing

Inventive Principle:
Principle #25Self-service

AI summary

A container includes a sealing system coupled to an interior surface of the container's lid or cover. The sealing system includes a rotatable latch that, when rotated, cooperates with a number of gears to and a cam assembly formed in the lid to actuate a number of arms or links. In one embodiment, some of the arms extend approximately radially from a driven gear and operate to move an engagement member of the sealing assembly into contact with a complementary engagement member coupled to a base portion of the container. This engagement, in turn, compresses a seal or gasket located between the lid portion and the base portion of the container.
