Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan lamp installations are difficult, time-consuming, labor-intensive, and aesthetically unpleasing, often requiring multiple people and posing safety risks due to the use of screws for fixation.
Innovation Solution
A ceiling assembly with a detachable connection between the bracket body and ceiling box, utilizing inclined guiding parts and reinforcing ribs for easy installation and disassembly, allowing single-person operation and enhancing structural compactness and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used for fixation in fan lamp installation, then the connection strength is improved, but the installation complexity and time consumption increase significantly
Solution Approach 1:
The connection system is segmented into separate components: a ceiling box with first connecting part, and a bracket body with second connecting part. This segmentation allows for modular assembly and disassembly without requiring complete dismantling of the entire fixture, significantly reducing installation time while maintaining connection strength through dedicated connecting parts.
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with a snap-fit connection system. The first connecting part on the ceiling box engages with the second connecting part on the bracket body through a simple insertion and snapping motion, eliminating the need for tools and multiple fastening operations while providing sufficient connection strength.
2Stability of the object's composition
If traditional fixation methods are used, then the structural stability is improved, but the ease of operation deteriorates due to requiring multiple people
Solution Approach 1:
The connection system incorporates dynamic elements including guiding parts that direct the insertion motion and limiting parts that control the engagement depth. This dynamic design allows a single operator to easily manipulate the connecting parts while ensuring stable structural connection through controlled engagement of the bracket body with the ceiling box.
3Reliability
If complex connection structures are used, then the connection reliability is improved, but the device complexity increases affecting aesthetics
Solution Approach 1:
The complex internal connection mechanisms are extracted and concealed within the ceiling box structure. The first connecting part is integrated into the ceiling box housing, hiding the mechanical complexity from view while maintaining reliable connection functionality. Only the essential engagement interface is exposed, preserving aesthetic appearance.
4Ease of repair
If detachable connections are implemented, then the ease of repair and maintenance is improved, but the connection strength may deteriorate
Solution Approach 1:
The connecting parts are pre-designed with built-in engagement features including guiding surfaces and limiting structures that ensure proper alignment and secure connection upon assembly. This preliminary design of the connection interface ensures that the detachable connection maintains sufficient strength while allowing for easy disassembly when needed for repair or maintenance.
