Solution Overview

Problem

Existing fan devices for switch cabinets are perceived as ineffective and non-variable, failing to provide effective cooling while adequately preventing dust introduction.

Innovation Solution

A fan support system with a modular design that allows for the insertion of either a flap device or a filter insert, enabling users to choose between improved air circulation or dust prevention, featuring a frame with a receiving area and holding means for inserts, and a separable cover hood for easy adaptation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a filter mat is installed in the fan device, then dust prevention is improved, but air flow is reduced

Engineering Contradiction:
Improvedust preventionVSAvoidair flow
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The fan device is divided into separate functional modules: a filter module with filter mats and a flap module with adjustable flaps. This segmentation allows independent optimization of each function - the filter can be positioned to minimize flow resistance while the flaps can be adjusted to maintain high air flow, resolving the contradiction between dust prevention and air flow efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flap device incorporates adjustable flaps that can dynamically adapt to different operating conditions. The flaps can be positioned to optimize air flow while the filter remains in place for dust prevention, allowing the system to maintain both high productivity and effective filtration simultaneously through dynamic adjustment

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a modular fan support system with exchangeable inserts is implemented, then adaptability is improved, but device complexity is increased

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fan support structure is designed as a universal base that can accommodate multiple types of inserts including filter mats, flap devices, and other functional elements. This multi-functional design allows a single standardized support structure to serve various applications, improving adaptability while actually reducing overall system complexity through standardization rather than increasing it

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

Solution Approach 2:

The modular inserts are designed to nest within the fan support structure, with components like flaps and filters fitting into designated compartments. This nesting approach allows easy installation and removal of different functional elements without requiring complex assembly procedures, thereby improving adaptability while keeping the device relatively simple

Inventive Principle:
Principle #7Nested doll (Nesting)
