Plastic Ceiling Profile Holder with Springy Catch Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing ceiling profiles in the transition between a wall and a ceiling require spring steel to maintain clamping force over time, making it difficult to use plastic holders effectively for permanent and secure mounting.
Innovation Solution
A plastic holder with a carrying leg at an acute angle, a support leg, and transverse holding legs that form a springy catch hook to engage with a catch stop of the ceiling profile, ensuring secure attachment without relying on clamping force, thus allowing plastic holders to be used for durable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring steel holders are used to maintain clamping force over time, then the mounting reliability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses a plastic holder instead of expensive spring steel, accepting that the plastic may degrade over time but designing the system so that the ceiling profile can be easily replaced anyway, making the holder effectively disposable while maintaining reliability during the useful life of the installation
Solution Approach 2:
The holder is divided into separate functional elements: the plastic holder body provides positioning and guidance, while the metal spring element provides the clamping force. This segmentation allows each component to be optimized for its specific function - plastic for cost and positioning, metal for reliable clamping force
2Ease of manufacture
If plastic holders are used to reduce device complexity, then ease of manufacture is improved, but the mounting reliability deteriorates due to loss of clamping force over time
Solution Approach 1:
The holder combines plastic and metal spring elements in a composite structure. The plastic portion is easy to manufacture and provides positioning, while the metal spring element maintains clamping force over time. This composite approach allows the holder to be manufactured simply while maintaining mounting reliability
Solution Approach 2:
The patent changes the material parameter from pure plastic to a combination of plastic and metal spring, allowing the holder to maintain clamping force over time while remaining easy to manufacture. The metal spring element compensates for the plastic's tendency to lose clamping force
3Ease of operation
If clamping action is used to secure the ceiling profile, then the mounting simplicity is improved, but the long-term security deteriorates due to plastic aging
Solution Approach 1:
The patent uses a dynamic spring element that automatically adjusts to maintain clamping force. The spring compensates for plastic aging by dynamically adjusting its force, ensuring long-term security while maintaining the simple clamping action installation process
4Ease of manufacture
If the holder structure is simplified to reduce device complexity, then ease of manufacture is improved, but the ability to dissipate loads onto the wall deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the load-bearing function in specific areas of the holder structure. The metal spring element and the engagement points with the wall are designed to handle loads, while other parts of the plastic holder can be simpler in shape for ease of manufacture
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 enables secure and long-lasting attachment of ceiling profiles using plastic holders, independent of plastic aging, with the springy catch hook providing additional security against unintentional detachment, while maintaining structural integrity and preventing rotation.
Implementation Method 1
the carrying leg is extended beyond the support leg to form a springy catch hook which interacts with a catch stop of the ceiling profile

AI summary
A device is described for fastening a ceiling profile (8) for the transition between a wall (9) and a ceiling (10) having a holder (1), which has a wall leg (2) and two holding webs (6), which engage in longitudinal grooves (7) of the ceiling profile (8). To provide simple structural conditions, it is proposed that the holder (1) forms a plastic profile having a carrying leg (3) which protrudes downward from the wall leg (2) at an acute angle, and having a support leg (4) which connects the wall leg (2) on top to the carrying leg (3), the holding legs (6) extending transversely to the wall leg (2) protrude from the carrying leg (3), and the carrying leg (3) is extended beyond the support leg (4) to form a springy catch hook (14), which interacts with a catch stop (16) of the ceiling profile (8).
