Solution Overview

Problem

Existing device hoods, particularly those for heat pumps, are difficult to assemble and disassemble, especially when permanently installed connections are present, making maintenance challenging due to the need to dismantle connected pipes and components.

Innovation Solution

A two-part device hood design with a releasable lock featuring a rotatable locking element that can be easily switched between open and closed positions, allowing for easy access and maintenance without disassembling connected pipes, using C-shaped grooves and a contact web for secure fixation and simplified handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a device hood with permanently installed connections is used, then the device can be securely installed with fixed connections, but maintenance becomes difficult and time-consuming requiring dismantling of pipes

Engineering Contradiction:
Improvesecure installationVSAvoidmaintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The device hood is divided into two separable parts: a first hood part that can be removed and a second hood part that remains installed. This segmentation allows the hood to provide secure installation when assembled while enabling easy maintenance by removing only the first hood part, leaving the second part with connected pipes in place.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a releasable lock with rotatable locking element is used, then the hood parts can be easily assembled and disassembled, but the locking mechanism adds device complexity

Engineering Contradiction:
Improveassembly and disassembly easeVSAvoidlocking mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking element is designed to be rotatable between a locked position (fixing the hood parts together) and an unlocked position (allowing separation). This dynamic mechanism enables easy assembly and disassembly through simple rotation while maintaining a secure fixed state when locked, balancing operational ease with structural simplicity.

Inventive Principle:
Principle #15Dynamics

3Ease of repair

If the first hood part is designed to be removable while the second remains installed, then maintenance is simplified by avoiding pipe dismantling, but the hood structure becomes more complex

Engineering Contradiction:
Improvemaintenance simplicityVSAvoidhood structure complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The hood is segmented into a first removable hood part and a second stationary hood part that remains installed during maintenance. This segmentation allows maintenance personnel to access components by removing only the first part without dismantling pipes connected to the second part, simplifying maintenance while accepting increased structural complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

Device hood (2), in particular for a heat pump (4), which extends in an axial direction (A) and has a first and a second hood part (10, 10a, 10b), the hood parts (10a, 10b) in the assembled state abut one another at separating edges (12) and can be pulled apart in a connecting direction (V) perpendicular to the axial direction (A), a releasable locking mechanism with at least one rotatable locking element (14) being arranged to fix the hood parts (10a, 10b) to one another in the assembled state characterized in that the locking element (14) can be reversibly transferred between an open and a closed position by rotation about an axis of rotation (D) and in that the hood parts (10a, 10b) can be pulled apart in the open position.
