Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for electronic devices on ceilings or walls are difficult to mount and dismount, often damaging the surface and becoming loose due to high spring requirements and reduced elasticity over time.
Innovation Solution
A fixing device with a mounting assembly and fixing assembly that uses a clamping member and guiding member to securely attach to a mounting hole, featuring a torsion spring and locking mechanism for quick installation and firm attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a press fastener with spring is used to fix the mounting plate, then the mounting plate can be suspended on the ceiling or wall, but the elastic force requirement is high and the spring becomes flexible after long use, causing the installation to loosen
Solution Approach 1:
The patent replaces the traditional spring-based press fastener with a mechanical expansion system. The expansion rod expands within the expansion hole to create a rigid mechanical lock between the fixing device and the mounting plate, eliminating the need for elastic springs and their associated reliability issues over time.
Solution Approach 2:
The fixing device is divided into separate functional components: the mounting plate, expansion holes, expansion rods, and limiting components. This segmentation allows each part to perform its specific function independently, with the expansion rod providing stable long-term fixation without the degradation problems of spring materials.
2Strength
If screws are used to fix the mounting plate on the ceiling or wall, then the mounting plate can be securely installed, but it is difficult to disassemble and may damage the ceiling or wall
Solution Approach 1:
The patent employs a dynamic expansion mechanism where the expansion rod can be pushed to expand for installation and then contracted or removed for disassembly. This dynamic system provides strong fixation during use but allows easy removal when needed, unlike static screw connections that require tools and may damage surfaces.
Solution Approach 2:
The expansion mechanism is designed to be self-locking through the interaction between the expansion rod and the expansion hole walls. The limiting component prevents over-expansion while the friction and geometric interference provide automatic locking, eliminating the need for additional fastening operations or tools during both installation and disassembly.
3Adaptability or versatility
If a traditional mounting plate with screws is used, then the electronic device can be mounted, but the installation process is time-consuming and requires tools
Solution Approach 1:
The patent extracts the fastening function from separate screws and integrates it into the mounting plate itself through the expansion holes and expansion rods. This integration allows the entire mounting operation to be performed by simply pushing the expansion rods, eliminating the need for separate fastening steps and tools, thereby dramatically increasing installation speed.
4Force
If the spring elastic force is increased to maintain firm installation, then the mounting plate remains secure, but the spring becomes more flexible and prone to loosening after long use
Solution Approach 1:
The patent replaces the elastic force mechanism with a rigid mechanical expansion system. The expansion rod creates direct mechanical contact and geometric interference with the expansion hole walls, providing stable fixation force without relying on material elasticity that degrades over time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and secure mounting and dismounting of electronic devices without damaging the surface, maintaining firm fixation without loosening.
Implementation Method 1
one end of the clamping member can be tilted towards the mounting plate to abuts against the plate
Implementation Method 2
two ends of a torsion spring are respectively wound around the mounting post
Implementation Method 3
there is an acute angle between the clamping member and the guiding member, and the clamping member obliquely abuts against the bottom surface of the plate

AI summary
A fixing device capable of mounting and dismounting quickly includes a mounting assembly and at least one fixing assembly, the mounting assembly includes a mounting plate, a fitting cylinder arranged on a bottom surface of the mounting plate, and at least one guiding member perpendicularly extending downward from the bottom surface of the mounting plate. The fitting cylinder attaches to the wall of the mounting hole, the mounting plate is provided on the top surface of the mounting plate around the mounting hole. The guiding member is provided in the fitting cylinder and extends out of the fitting cylinder. The fixing assembly is provided at the guiding member and abuts against the bottom surface of the plate, thereby clamping the plate between the mounting plate and the fixing assembly.
