Solution Overview

Problem

Existing ventilation devices face challenges in quick and safe assembly, particularly in emergency settings where ease of use and durability are crucial.

Innovation Solution

The input/output device is secured directly to the functional arrangement using a lifting mechanism, with a locking mechanism that ensures a positive locking engagement, allowing for a backlash-free assembly by connecting the input/output device and functional arrangement to the device housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the input/output device is separately assembled to the device housing, then assembly flexibility is improved, but assembly time and complexity increase

Engineering Contradiction:

Improveassembly flexibilityVSAvoidassembly time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent combines the input/output device and the functional arrangement into a single pre-assembled unit that is then attached to the device housing as one integrated component. This merging eliminates the need for separate assembly steps for each component, thereby reducing assembly time while maintaining the flexibility of modular construction.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If the input/output device is accessible from outside the housing, then ease of operation is improved, but protection from external influences deteriorates

Engineering Contradiction:

ImproveaccessibilityVSAvoidprotection from external influences

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The input/output device is nested within a protective housing structure that provides shielding from external influences such as mechanical shocks and contamination. The device remains accessible through a strategically positioned opening in the housing, allowing operators to interact with the device while the housing protects it from harmful external factors.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Reliability

If a locking mechanism is implemented, then assembly security is improved, but device complexity increases

Engineering Contradiction:

Improveassembly securityVSAvoidmechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is designed to automatically engage and secure the input/output device to the device housing without requiring additional manual intervention or complex activation procedures. The mechanism self-activates upon proper positioning of the components, providing secure assembly while maintaining simplicity in operation.

Inventive Principle:

Principle #25Self-service
