Ceiling Ventilation Assembly with Frame-Suspended Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ventilation box installation methods are cumbersome and risky, involving heavy equipment and potential misalignment of anchoring members, which complicates the fixing process and affects safety and aesthetics.
Innovation Solution
A ventilation assembly with a lightweight frame that is fixed to the ceiling first, allowing the ventilation box to be suspended from pre-positioned fastening members, ensuring precise alignment and reducing installation time and risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ventilation box is directly fixed to the ceiling using anchoring members, then the fixing operation is complex and time-consuming, but the structural strength is sufficient
Solution Approach 1:
The fixing system is divided into two independent parts: a frame that is fixed to the ceiling first, and a ventilation box that is subsequently suspended from the frame. This segmentation allows the heavy ventilation box to be installed separately from the ceiling anchoring process, significantly simplifying the operation and reducing installation time while maintaining structural strength.
Solution Approach 2:
The frame is preliminarily fixed to the ceiling before the ventilation box is installed. This preliminary action establishes the mounting structure in advance, allowing the ventilation box to be simply suspended from pre-positioned fastening members rather than requiring complex direct anchoring of the heavy box to the ceiling.
2Reliability
If anchoring members are used to directly fix the ventilation box to the ceiling, then the structural strength is sufficient, but misalignment and blockages occur during installation
Solution Approach 1:
By separating the anchoring function (performed by the frame with integrated fastening members) from the ventilation box, the system ensures that alignment-critical components are pre-positioned on the frame. This eliminates the risk of misalignment between anchoring members and the ventilation box during installation, as the fastening members are already correctly positioned on the frame structure.
Solution Approach 2:
The frame acts as an intermediary structure between the ceiling and the ventilation box. It provides pre-positioned fastening members that serve as reliable attachment points, eliminating the need for direct alignment between ceiling anchoring members and the ventilation box, thus preventing misalignment and blockages.
3Measurement precision
If the ventilation box is held against the ceiling using lifting equipment, then precise positioning is achieved, but the installation process becomes tedious and risky
Solution Approach 1:
The system separates the positioning function (achieved by fixing the frame to the ceiling) from the weight-bearing function (achieved by suspending the ventilation box from the frame). This allows the frame to be precisely positioned and fixed to the ceiling first, then the ventilation box is simply suspended from pre-positioned fastening members, eliminating the need for prolonged use of lifting equipment and reducing installation time and risk.
4Strength
If fixing lugs are used to attach the ventilation box to the ceiling, then the structural connection is strong, but aesthetic appearance is compromised
Solution Approach 1:
The fixing lugs and anchoring members are extracted from the ventilation box structure itself and relocated to the frame structure. This allows the ventilation box to have a clean, aesthetic appearance without exposed fixing elements, while the frame (which can be positioned within or behind the box perimeter) contains all the structural fixing components.
Solution Approach 2:
The frame serves as an intermediary that carries all the fixing lugs and anchoring members, separating these structural elements from the ventilation box. This allows the ventilation box to maintain its aesthetic appearance while the frame provides the necessary structural connection to the ceiling, with the frame's fixing components positioned within the box perimeter.
