Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional strapping devices are used with multiple instruments and complex surgical techniques, then the strapping function can be achieved, but the surgical time increases and the risk of infection increases
Solution Approach 1:
The patent combines the strapping element and closing member into a single integrated device. The closing member is directly attached to the strapping element, eliminating the need for separate instruments to apply and secure the strapping. This merging of components streamlines the surgical procedure while maintaining the essential strapping function for fracture stabilization.
2Reliability
If traditional strapping devices with multiple instruments are used, then the strapping function can be achieved, but the complexity of the surgical procedure increases
Solution Approach 1:
The strapping element and closing member are merged into a single integrated device, reducing the number of separate instruments and steps required during surgery. The closing member is pre-attached to the strapping element, simplifying the application process and reducing procedural complexity while maintaining effective fracture stabilization.
Solution Approach 2:
The integrated device is designed to be self-contained, with the closing member already attached to the strapping element. This self-service design eliminates the need for multiple separate instruments and complex manipulation steps, allowing the surgeon to apply the strapping more directly and with less procedural complexity.
3Force
If additional clamping pieces are used for tensioning, then the tensioning function is achieved, but the number of instruments and steps increases
Solution Approach 1:
The closing member is integrated directly with the strapping element, combining the tensioning and securing functions into a single component. This eliminates the need for separate clamping pieces or additional instruments to achieve proper tensioning, reducing the overall number of instruments required while maintaining effective force application for fracture stabilization.
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 device simplifies the surgical procedure by reducing the number of instruments needed and minimizing post-operative pain, while ensuring stable bone compression and tension maintenance during the healing process.
Implementation Method 1
sliding a portion of the adjustable loop in an interior volume of a sleeve arranged in the textile element
Implementation Method 2
perimeter of the elongate hollow textile element is adjustable by sliding a portion of the adjustable loop in an interior volume of a sleeve
Implementation Method 3
The bone assembly or the bone held by the strapping wire must undergo traction concomitant with torsion to remain in its implantation position
Implementation Method 4
the metallic strappings have limited elastic deformation, which compromises their ability to maintain compression on the bone fragments held together

AI summary
The present disclosure relates to an implantable strapping device comprising an elongate hollow textile element comprising an attachment portion and an adjustable loop, the perimeter of the adjustable loop is adjustable by sliding a portion of the adjustable loop in an interior volume of a sleeve arranged in the textile element, and a strapping closing member comprising a front part with which the adjustable loop or the attachment portion is connected, and a rear part comprising a first U-shaped housing configured to receive part of the attachment portion or of the adjustable loop. The strapping device thus comprises a clamping position of the strapping by sliding the adjustable loop in the sleeve, and a locking position in which the sliding of the adjustable loop is prevented by the sleeve.
