U-Shaped Clamping Device With Wing Nails For Plaster Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for attaching pipes or tubes to plaster boards lack sufficient retaining force and often damage the surface, especially when using straight nails on plaster walls, which do not provide a secure attachment and can leave unsightly marks.
Innovation Solution
A U-shaped clamping device with wing nails and a central nail, where the wing nails are designed to bend sideways upon insertion, and a bead or collar along the U-shaped main body to prevent deformation and enhance grip, ensuring secure attachment without damaging the plaster board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If straight nails are used to attach the clamping device to plaster boards, then the attachment process is simple, but the retaining force is insufficient and the surface may be damaged
Solution Approach 1:
The nail geometry is changed from straight to bent/winged configuration. This parameter change allows the nail to deform plastically upon insertion, creating lateral expansion that increases friction and mechanical interlocking with the plaster board, thereby significantly improving retaining force while maintaining attachment simplicity
Solution Approach 2:
The attachment means are designed to be deformable during the attachment process. The bent nails dynamically change shape upon insertion, transitioning from a compact form to an expanded form that provides superior anchoring. This dynamic behavior enables the system to adapt to the plaster board material and achieve reliable attachment
2Reliability
If the clamping device is forced into the plaster board, then attachment is achieved, but the U-shaped main body may deform if hit aslant
Solution Approach 1:
The clamping device is segmented into distinct functional zones: the U-shaped main body for clamping the pipe, the attachment means for securing to the plaster board, and reinforcement elements (bead/collar) for structural support. This segmentation allows each part to be optimized independently - the main body remains lightweight while the reinforcement elements provide necessary rigidity against lateral impacts
Solution Approach 2:
The clamping device employs composite construction combining different material properties in different regions. The main body may use a lighter material for ease of installation, while strategic reinforcement elements (bead or collar) provide enhanced stiffness and impact resistance. This composite approach achieves both attachment security and structural stability
3Reliability
If nails are driven into the plaster board, then the clamping device is secured, but the front surface of the plaster board may be damaged or deformed
Solution Approach 1:
The bent/winged nails act as intermediaries between the clamping device and the plaster board. Their deformable design allows them to absorb insertion forces and distribute loads over a larger area within the plaster board, reducing point loads that could cause surface deformation or damage to the front side
Solution Approach 2:
The nails are pre-configured in a bent or winged shape that anticipates the insertion process. This preliminary configuration ensures that upon insertion, the nails immediately engage the plaster board material in a controlled manner, creating secure anchorage without requiring excessive force that could damage the surface

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 clamping device provides a strong and secure attachment to plaster boards without deforming the U-shaped main body or damaging the surface, ensuring the pipe or tube remains fixed and aesthetically intact, meeting European building standards.

AI summary
The present invention relates to a clamping device (10) intended for attaching a pipe (18), such as a water pipe, gas pipe or ducts for pulling for electrical cables, to a supporting surface (17) comprising plaster boards. The clamping device (10) comprises a U-shaped main body (11) having a diameter which more or less corresponds to the diameter of the pipe (18). The clamping device (10) is at its two free ends provided with attachment means (12) intended to be forced into the plaster board for attaching the pipe (18), in order to attach the clamping device (10) to the supporting surface (17). The clamping device (10) (15) is along its curved part, provided with at least one outwards projecting, curved, continuous bead or collar (16) following the curved part (15) of the U-shaped main body (11). Each attachment means (12) comprises a centrally arranged nail (14) and two wing nails (13) positioned on each side of the centrally arranged nail (14), the two wing nails (13) being configured to bend in sideways direction away from the central nail (14) when the clamping device (10) is attached to the plaster board (17), enhancing the attachment force of the attachment means (12) to the plaster board (17).
