Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling mount structures for hanging fans are difficult and inconvenient to align and fix into desired positions due to their design, making installation cumbersome.
Innovation Solution
A ceiling mount structure comprising a ceiling mount disc with an internal and external disc portion, where the external disc has arc slots and screw thread portions for mounting the fan motor, and a cover with adjustable fixing portions and a gasket for secure engagement, allowing for quick and convenient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cover and ceiling mount base are fixed at a height proximate to the ceiling, then the structural stability is improved, but the ease of alignment and fixation deteriorates
Solution Approach 1:
The ceiling mount structure is divided into two main segments: a ceiling mount base that is fixed to the ceiling, and a cover that can be independently positioned and then secured. This segmentation allows the base to provide structural stability while the cover can be easily aligned and fixed at the desired height near the ceiling without requiring complex simultaneous alignment of all components.
Solution Approach 2:
The ceiling mount base is preliminarily fixed to the ceiling first, establishing a stable foundation. Then the cover is separately positioned and aligned with the pre-installed base, making the alignment process easier since one component is already in its final position. This preliminary action resolves the contradiction by stabilizing the base first while allowing flexible positioning of the cover.
2Stability of the object's composition
If the cover and ceiling mount base are fixed at a height proximate to the ceiling, then the structural stability is improved, but the installation time increases
Solution Approach 1:
By segmenting the structure into a ceiling mount base and a separate cover, the installation process can be divided into two simple steps: first fix the base to the ceiling, then attach the cover. This is much faster than trying to simultaneously align and fix multiple components at ceiling height, thus reducing installation time while maintaining structural stability.
Solution Approach 2:
The ceiling mount base is installed first as a preliminary step, serving as a pre-prepared mounting platform. This allows the cover to be quickly attached without requiring complex real-time alignment, significantly reducing the total installation time while ensuring the final structure maintains its stability near the ceiling.
3Measurement precision
If the arc slot width is smaller than the circular hole diameter, then the positioning precision is improved, but the ease of assembly deteriorates
Solution Approach 1:
The fixing portion is designed with a width that allows it to dynamically transition from a loose state during assembly to a constrained state during operation. During assembly, the fixing portion can freely move within the arc slot for easy positioning. Once assembled, the gasket is compressed to create resistance, converting the dynamic freedom into static precision, thus resolving the contradiction between ease of assembly and positioning precision.
Solution Approach 2:
The effective width of the fixing portion changes depending on the assembly state. During assembly, the full width allows easy movement within the arc slot. During operation, the gasket compression reduces the effective clearance, increasing positioning precision. This parameter change resolves the contradiction by providing both ease of assembly and positioning precision at different stages.
