Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation fan mounting structures face difficulties when the distance between the ceiling and the roof is small, as the bracket assembly cannot be easily inserted due to space constraints, leading to obstruction and incomplete mounting.
Innovation Solution
A ventilation fan mounting structure featuring a bracket assembly with rotatable U-shaped brackets connected by rivets, allowing for angled insertion and reduced space requirements, along with an adapter plate and temporary fixing structures for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bracket assembly is inserted at an angle to fit through the ceiling opening, then the insertion difficulty is reduced, but the mounting precision and horizontal positioning are compromised
Solution Approach 1:
The bracket assembly transitions from a static rigid structure to a dynamic adjustable structure. The connection members are designed to be adjustable in length and angle, allowing the bracket to adapt its configuration during insertion and then lock into a precise horizontal mounting position. This dynamic adjustment capability resolves the contradiction by enabling both easy angled insertion and precise final positioning.
Solution Approach 2:
The invention changes the geometric parameters of the bracket assembly, specifically making the connection members adjustable in length and angle. This parameter adjustability allows the bracket to be inserted at various angles through the ceiling opening and then adjusted to achieve precise horizontal mounting alignment, simultaneously improving insertion ease and maintaining mounting precision.
2Strength
If the bracket assembly is designed with a fixed rigid structure, then the structural strength is high, but the ease of insertion through limited ceiling openings is reduced
Solution Approach 1:
The bracket assembly incorporates dynamic adjustable connection members that can change their configuration during insertion. These connection members maintain structural strength when locked in position while allowing flexible adjustment during the insertion process, thereby resolving the contradiction between structural strength and insertion ease.
Solution Approach 2:
The bracket assembly is segmented into multiple components including side members, connection members, and mounting members. The connection members are further segmented to be adjustable in length and angle. This segmentation allows each part to fulfill its specific function - providing strength where needed and flexibility where required for insertion.
3Adaptability or versatility
If the connection members are made adjustable in length and angle, then the adaptability to different ceiling configurations is improved, but the device complexity increases
Solution Approach 1:
The adjustable connection members serve multiple functions: they provide structural support, enable angle adjustment for different insertion orientations, accommodate varying ceiling opening sizes, and allow positioning at different heights. This multi-functionality achieves high adaptability to different ceiling configurations while avoiding the need for multiple different bracket designs, thereby managing device complexity.
Solution Approach 2:
The connection members are designed with adjustable length and angle capabilities, providing dynamic adaptability to various ceiling configurations. This dynamic design allows a single bracket assembly design to accommodate multiple installation scenarios without requiring complex specialized components for each configuration.
