Solution Overview
Problem
Existing clamping devices face challenges in secure and cost-effective positioning of the clamping collar relative to the article, especially when a leaktight fastening is required, as existing solutions often compromise on clamping quality or require complex fastening mechanisms.
Innovation Solution
A clamping device with a securing plate that deforms to match the curvature of the belt during tightening, allowing relative movement and simple bracing, combined with a positioning portion that can be pre-positioned without affecting the clamping diameter or quality, using a tangential screw mechanism for efficient tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fastening mechanism is used to secure the positioning plate to the belt, then the positioning reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The positioning plate utilizes the bracing effect of the belt itself to achieve secure positioning. The plate is simply placed against the belt's inner face, and the belt's structural rigidity provides the necessary support without requiring any additional fastening components. This self-service approach eliminates complex fastening mechanisms while maintaining positioning reliability.
Solution Approach 2:
The invention extracts the fastening function from the system by eliminating the need for fastening mechanisms entirely. The positioning plate is retained solely through the bracing effect of the belt structure, removing unnecessary components and simplifying the overall device while achieving the desired positioning reliability.
2Stability of the object's composition
If the positioning plate is rigidly fixed to the belt, then the positioning stability is improved, but the clamping quality deteriorates due to interference with belt contraction
Solution Approach 1:
The positioning plate is designed to be dynamically adaptable during the clamping process. In the initial state, the plate is braced against the belt for stable positioning. During tightening, the plate deforms elastically to match the belt's curvature changes, allowing the belt to contract freely without rigid constraints. This dynamic behavior maintains both positioning stability and clamping quality.
Solution Approach 2:
The plate's physical state changes during the clamping process. Initially, the plate maintains a rigid braced position for stability. As the belt contracts during tightening, the plate deforms to match the changing curvature parameter of the belt, transitioning from a rigid state to a deformed state that accommodates the belt's dimensional changes without compromising clamping quality.
3Ease of operation
If the plate deforms during tightening to match belt curvature, then the relative movement between belt and plate is enabled, but the positioning precision may be compromised
Solution Approach 1:
The positioning plate is pre-positioned against the belt's inner face in a braced configuration before tightening begins. This preliminary positioning establishes the correct relative location between the plate and belt. The deformation during tightening is a controlled secondary effect that enables smooth operation while the pre-established braced position ensures positioning precision is maintained throughout the process.

AI summary
A device includes a clamping collar having a belt that has two substantially cylindrical faces and that is suitable for being tightened around an article to be clamped; and at least one positioning including a securing plate that is disposed facing a first face of the belt while being retained relative to the belt; and a positioning portion that is suitable for positioning the device relative to the article to be clamped. When the collar is in its initial, non-tightened state, the securing plate is braced against the first face of the belt, wherein at the beginning of tightening, the plate deforming causes the bracing effect to cease, thereby allowing the belt and the plate to move relative to each other. The plate is suitable for being deformed while the collar is being tightened onto the article so as to present curvature that matches the curvature of the belt.
