Sliding Clamping Element for Cable Duct Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing device installation boxes and other electrical installation devices on cable routing ducts are cumbersome and time-consuming, particularly with front-locking installations, as they require complex positioning and fixing processes that complicate assembly and disassembly.
Innovation Solution
A device featuring a separate clamping element that is slidably integrated into the holding frame, allowing for easy attachment and detachment without screws, utilizing snapping or clamping elements to create a friction lock with the duct's shape-retaining profiles, enabling quick and efficient assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw-fixing methods are used to secure device installation boxes on cable routing ducts, then the fixation is secure and stable, but the assembly and disassembly process becomes time-consuming and complex
Solution Approach 1:
The fixing system is divided into separate functional components: a holding frame that attaches to the duct, a device installation box, and a separate clamping element. This segmentation allows each component to be optimized independently and facilitates quick assembly by simply connecting the components together without complex fastening procedures.
Solution Approach 2:
The clamping element is designed to be displaceable between a release position and a clamping position. In the release position, the holding frame can be freely positioned on the duct. When displaced to the clamping position, it engages the shape-retaining profiles to create a friction lock, providing secure fixation. This dynamic mechanism enables both easy positioning and reliable fixing.
2Reliability
If front-locking installation methods are used, then the device installation box can be secured to the duct, but the positioning and subsequent fixing becomes cumbersome and complex
Solution Approach 1:
The holding frame is pre-equipped with clamping elements that are initially in a release position, allowing the frame to be freely moved and positioned on the duct. Once positioned, the clamping elements are displaced to engage the shape-retaining profiles, performing the fixation action after positioning rather than requiring positioning through a complex locking mechanism.
Solution Approach 2:
The clamping element acts as an intermediary between the holding frame and the duct's shape-retaining profiles. It provides a simple displacement action that transforms the holding frame from a movable state to a securely fixed state, mediating between the ease of positioning and the security of attachment.
3Reliability
If complex assembly procedures are used to secure electrical installation devices, then the fixation is secure, but the disassembly and repositioning becomes difficult and time-consuming
Solution Approach 1:
The clamping element is designed with a displaceable mechanism that can easily transition between clamping and release positions. To disassemble, the clamping element is simply displaced from the clamping position to the release position, releasing the friction lock and allowing the holding frame to be removed from the duct. This dynamic design provides both secure fixation and easy disassembly.
Solution Approach 2:
The friction lock mechanism inherently provides both fixation and release capabilities through the same clamping element. The same displacement action that creates secure attachment can be reversed to enable easy removal, making the system self-servicing without requiring different mechanisms for assembly and disassembly.
4Reliability
If multiple assembly materials and tools are required for securing devices, then the fixation can be secure, but the assembly process becomes more complex and requires more resources
Solution Approach 1:
The clamping element utilizes the elastic properties of the holding frame material itself to create the friction lock, rather than requiring separate fasteners, adhesives, or other assembly materials. The system uses the inherent mechanical properties of the components to achieve secure fixation, eliminating the need for additional assembly materials and reducing overall system complexity.
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
This solution simplifies the assembly and disassembly of electrical installation devices by allowing them to be moved along the duct during positioning and securely fixed with minimal effort, reducing the need for tools and assembly materials, and facilitating easy repositioning or removal.
Implementation Method 1
whereby the clamping element causes an inner strip with clamping lugs formed thereon to be pressed inwards elastically against the shape-retaining profiles of the duct base
Implementation Method 2

AI summary
The device has a holding frame (10) defining a central opening, and a clamping element (20) inserted into a frame element (12) and comprising a base body (23). The clamping element is inserted into the frame element, such that the clamping element is movable from a mounting position to a locking position along a guide (19) i.e. rail. A flange (28) lies on the frame in the mounting position, and the clamping element presses an inner bar of the frame against a form-holding profile i.e. cover holding profile, of a channel lower part for producing a frictional connection in the locking position.
