Solution Overview

Problem

Existing portable containers face challenges in maintaining an open configuration against accidental closure, especially in professional applications where the containers are designed to carry sensitive equipment, and the existing solutions for coupling gas cylinder actuators compromise sealing integrity and are not easily adaptable or adjustable.

Innovation Solution

A coupling assembly that includes inserts and a slider with a profiled element, allowing for flexible positioning and anchoring of the safety device, enabling versatile and adjustable coupling to the shell portions without compromising the container's sealing integrity, using existing seats or creating new ones as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gas cylinder actuators are coupled to shell portions using traditional methods (screws, nails, or inserts in pockets), then the safety device can contrast accidental closure and facilitate opening, but the sealing integrity of the container is compromised due to holes in the shell portions or complex insert structures

Engineering Contradiction:
Improvesealing integrityVSAvoidcoupling complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

A coupling assembly acts as an intermediary component between the gas cylinder actuator and the shell portion. This assembly includes a first element that couples to the actuator and a second element that couples to the shell portion, allowing the actuator to be mounted without direct attachment to the shell, thus preserving sealing integrity while enabling functional coupling.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The coupling assembly is divided into multiple separate elements: a first element for actuator coupling and a second element for shell portion coupling. This segmentation allows each element to be optimized for its specific function - the first element can have holes for actuator attachment while the second element interfaces with the shell portion without compromising its sealing surface.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If fixed pockets are provided in shell portions for actuator coupling, then the actuator can be mounted, but the positioning and adjustment of the actuator are limited

Engineering Contradiction:
Improveactuator positioning flexibilityVSAvoidpocket configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling assembly introduces dynamic adjustability to the actuator mounting system. The first element can be positioned at different locations along the shell portion wall, and the second element can be adjusted relative to the first, allowing the actuator to be mounted in various positions and orientations without requiring multiple fixed pockets or complex reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling assembly serves multiple functions: it provides structural support for the actuator, enables adjustable positioning, maintains sealing integrity, and facilitates easy installation and removal. This multi-functionality replaces the need for dedicated fixed pockets, as the coupling assembly can be adapted to various mounting requirements using the same basic structure.

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

3Strength

If the container is designed to carry heavy equipment, then the shell portions must be rigid and strong, but the weight and dimensions of the container increase

Engineering Contradiction:
Improveshell strengthVSAvoidcontainer weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The coupling assembly segments the load-bearing functions from the sealing functions. The shell portion maintains its structural integrity for carrying heavy equipment, while the coupling assembly provides the necessary attachment points for the actuator without requiring additional reinforcement or thickening of the shell walls, thus avoiding increased weight.

Inventive Principle:
Principle #1Segmentation
