Movable Wing Mounting Frame for False Ceiling Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing built-in frame fastening devices for false ceilings are insecure, leading to difficult installations due to the risk of the pivotable element causing the frame to tilt, making it challenging to secure the frame in place.
Innovation Solution
A mounting frame with movable wing elements that transition between a retracted and extended state, secured by a spring element, allowing for easy assembly and secure fixation, where the wing elements are braced against each other to prevent retraction and ensure clamping of the false ceiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pivotable element is used to engage behind the false ceiling, then the installation frame can be mounted in a false ceiling, but the pivotable element can cause the installation frame to tilt, making the installation more difficult
Solution Approach 1:
The wing element is designed to be movable between a retracted position (for insertion) and an extended position (for engagement). During installation, the wing element can be moved to the extended position to engage behind the false ceiling, then returned to the retracted position to prevent tilting. This dynamic positioning resolves the contradiction by allowing the element to serve different functions at different stages of installation.
Solution Approach 2:
The wing element is pre-configured with a retracted position that prevents tilting during the insertion phase. By having the wing element automatically retractable or manually movable to the retracted position before insertion, the design preliminarily prepares the frame for stable insertion without the risk of tilting, thus improving ease of operation while maintaining adaptability.
2Reliability
If the wing element is made movable to extend beyond the frame, then the frame can be secured to the false ceiling, but the spring-loaded element requires manual holding during insertion
Solution Approach 1:
The wing element is designed with automatic retraction capability through the spring mechanism. After the frame is inserted into the false ceiling, the spring automatically returns the wing element to its retracted position without requiring the installer to manually hold it back. This self-service mechanism eliminates the need for manual holding during insertion while maintaining the securing capability when the wing element is extended.
Solution Approach 2:
The wing element transitions dynamically between extended and retracted positions based on the installation stage. During insertion, it retracts automatically; during engagement, it extends to secure the frame. This dynamic behavior resolves the contradiction by providing the securing function when needed while eliminating the manual holding requirement through automatic retraction.
3Reliability
If the wing element is extended beyond the frame cross section, then the false ceiling can be clamped, but the frame cross section increases making insertion difficult
Solution Approach 1:
The wing element is designed to change its position dynamically: retracted during insertion to maintain a small frame cross-section for easy passage through the ceiling opening, and extended during engagement to provide the clamping capability. This dynamic transformation resolves the contradiction by allowing the same element to serve both purposes at different stages.
Solution Approach 2:
The mounting frame is segmented into a fixed body and a movable wing element that can independently change position. This segmentation allows the wing element to be retracted during insertion (reducing overall cross-section) and extended during engagement (providing clamping), thus resolving the contradiction between insertion ease and clamping capability.
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
The solution provides a secure and quick installation process with reduced effort, ensuring the frame is firmly fixed without manual holding of spring-loaded elements and transmitting force for effective clamping, thus preventing unintentional retraction or tilting.
Implementation Method 1
The first and the second wing element are braced against one another by a spring element, so that a movement of the second wing element in the first state causes the fixation of the first wing element to be released.

AI summary
The mounting frame (100) has a body (10) and wing elements (20,30) that are supported at the body in a movable manner. The mounting frame has a retracted condition with smaller cross section and another extended condition with greater cross section. The former wing element is retracted in the former condition in the smaller cross section of the mounting frame and is fixed at the body. The former wing element is extended in the latter condition over the smaller cross section.
