Hinged Fan Support Element for Maintenance Access Without Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fan support systems require complete dismantling for maintenance, which is time-consuming and inefficient, especially when cleaning heat exchangers in refrigeration and air conditioning systems.
Innovation Solution
A support element with a hinge mechanism on the wall ring allows the fan to be pivoted away from the mounting wall for maintenance, eliminating the need for complete disassembly by using a hinge with bearing receptacles and journals for secure attachment and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan is firmly fixed to the mounting wall, then stability and reliability are improved, but maintenance work becomes time-consuming and complex
Solution Approach 1:
The support element incorporates a hinge mechanism that transforms the static fixed connection into a dynamic system. The wall ring can pivot between a mounted position (providing stability) and a maintenance position (enabling easy access). This dynamic capability allows the system to adapt between operational reliability and maintenance ease, resolving the contradiction between firm fixation and simple maintenance.
2Ease of operation
If the wall ring is completely dismantled for maintenance, then access for cleaning is improved, but time and effort are increased
Solution Approach 1:
The support element is segmented into the wall ring and the mounting wall connection. The hinge mechanism allows the wall ring to be separated from the mounted position without completely dismantling the entire assembly. This segmentation enables partial disconnection - the wall ring can be pivoted away for cleaning access while remaining connected through the hinge, significantly reducing the time and effort required compared to complete dismantling.
3Ease of repair
If a hinge mechanism is added to the wall ring, then maintenance ease is improved, but device complexity is increased
Solution Approach 1:
The hinge acts as an intermediary mechanism between the wall ring and the mounting wall. Instead of creating a complex dismantling procedure, the hinge provides a simple pivot connection that enables easy movement. The bearing receptacles and journals further simplify the hinge construction by providing straightforward bearing solutions. This intermediary element adds minimal complexity while dramatically improving maintenance ease.

AI summary
The present invention relates to a support element (2) for holding a fan (1), in particular an axial fan, comprising a wall ring (4) for receiving the fan (1). The wall ring (4) has on its outer periphery a hinge (20) consisting of a first hinge part (22) that is connected to the wall ring (4) and a second hinge part (24) that can be pivoted about a hinge axis (X) relative to the first hinge part (22). The invention further relates to a fan (1) comprising such a support element (2).
