U-Profile Cable Fastener for Tool-Free Wall Groove Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening methods for securing pipes and conduits in wall grooves are time-consuming, require tools, pose safety risks, and are difficult to implement, especially in hard masonry, and often damage the pipes or cables.
Innovation Solution
A fastening element designed as an upwardly open U-profile with friction-enhancing ribs on its legs and spring-like wings, allowing it to be easily pressed into wall grooves by hand without tools, providing a secure hold and facilitating quick installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nail clamps with hand tools are used to drive nails into masonry, then fastening is achieved, but installation time increases and injury risk arises
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (nails, hammers, hand tools) with a spring-elastic deformation system. The fastening element uses its own elastic properties to expand and secure itself in the wall groove without requiring external driving tools, thereby eliminating installation time loss and injury risks while maintaining fastening security.
Solution Approach 2:
The fastening element is designed to perform its own installation through spring-elastic deformation. When pressed into the wall groove, it automatically expands and secures itself without requiring external tools or additional operations, making the system self-installing and eliminating the need for manual driving operations.
2Reliability
If plastic wall plates with nails are used, then fastening is achieved, but plaster must be chipped away and installation becomes more complex
Solution Approach 1:
The patent extracts the nail-driving operation and separate wall plate components from the fastening system. The integrated fastening element combines the securing function and installation simplicity into a single component that expands within the groove, eliminating the need for separate nails and the complex operation of chipping away plaster.
Solution Approach 2:
The patent merges the wall plate and fastening mechanism into a single integrated element. The spring-elastic body combines the structural support function with the self-securing mechanism, eliminating the need for separate components and simplifying the overall installation process.
3Reliability
If traditional clamps with nails or screws are used, then pipes are secured, but tool requirements increase and portability decreases
Solution Approach 1:
The fastening element is designed to perform its own installation through spring-elastic deformation. When pressed into the wall groove, it automatically expands and secures itself without requiring external tools or additional operations, making the system self-installing and eliminating the need for manual driving operations.
Solution Approach 2:
The patent utilizes changes in the physical state of the fastening material through spring-elastic deformation. The material transitions from a compressed state during insertion to an expanded state for securing, allowing tool-free installation while maintaining portability and pipe securing reliability.
4Strength
If hard masonry is used, then structural strength is improved, but nail driving becomes difficult or impossible
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (nails, hammers, hand tools) with a spring-elastic deformation system. The fastening element uses its own elastic properties to expand and secure itself in the wall groove without requiring external driving tools, thereby eliminating installation time loss and injury risks while maintaining fastening security.
Solution Approach 2:
The patent utilizes changes in the physical state of the fastening material through spring-elastic deformation. The material transitions from a compressed state during insertion to an expanded state for securing, allowing tool-free installation while maintaining portability and pipe securing reliability.
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 fastening element securely holds cables and pipes in place without tools, is easy to install, cost-effective, and can be transported without additional equipment, ensuring safe and efficient installation.
Implementation Method 1
spring-like wings molded at its free ends at an acute angle downwards in the direction of the U-bottom
Implementation Method 2
a break in the U-shaped base, which creates an additional spring effect
Implementation Method 3
friction-enhancing means on the outer wall side of its two U-shaped legs... the friction-enhancing means are designed as ribs
