Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orbital covering grids are often too large and not adapted to individual skull bones, making them difficult to fit and adjust, which complicates the precise treatment of orbital floor injuries.
Innovation Solution
An orbital covering grid with alignable webs and recesses forming a predetermined breaking line, allowing manual adjustment without tools, and made from a titanium alloy for stability and biocompatibility, featuring elongated recesses and radial protrusions for secure attachment, with a method involving a negative mold for patient-specific production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard orbital covering grid is used, then the grid provides structural support for the orbital floor, but the grid is too large and not adapted to individual skull bones, making it difficult to fit and adjust
Solution Approach 1:
The orbital covering grid is designed with a lattice structure consisting of multiple bars arranged in a net-like pattern, creating modular segments that can be selectively removed. This segmentation allows the grid to be customized to fit individual skull bone contours while maintaining structural support functionality.
Solution Approach 2:
The grid incorporates predetermined breaking lines along which bars can be easily removed or adjusted during surgery. This dynamic design enables the grid to be adapted intraoperatively to match the specific anatomy of each patient's orbital floor, transforming a static implant into a customizable solution.
2Area of stationary object
If the orbital covering grid is made large to cover the orbital floor, then adequate coverage is provided, but the grid becomes difficult to adapt to individual contours
Solution Approach 1:
The large grid structure is divided into multiple smaller lattice units formed by intersecting bars. This segmentation allows selective removal of specific bars along predetermined breaking lines, enabling the grid to conform to individual orbital contours while maintaining overall coverage of the orbital floor.
Solution Approach 2:
Different regions of the grid can be selectively modified by removing specific bars in certain areas while leaving other areas intact. This local customization allows the grid to adapt to specific contour requirements of individual orbital floors without compromising overall coverage.
3Stability of the object's composition
If the orbital covering grid is made rigid for stability, then structural support is provided, but the grid becomes difficult to adjust and fit precisely
Solution Approach 1:
The grid incorporates predetermined breaking lines that allow specific bars to be easily removed or adjusted during surgery. This creates controlled weak points in the rigid structure, enabling intraoperative adaptation and precise fitting while maintaining overall structural stability for support functionality.
Solution Approach 2:
The rigid lattice structure is segmented into multiple bars connected at junctions, with predetermined breaking lines positioned along specific bars. This segmentation allows selective removal or adjustment of individual bars without compromising the structural integrity of the remaining grid framework.

AI summary
The invention relates to an eye socket covering grid (1) with a perforated main part which forms webs (4) and which has an outer terminating edge (6). Multiple elongated recesses (5, 8) which are separated from the terminating edge (6) by a web (4) and which are directly adjacent at the terminating edge are arranged so as to follow at least one section of the terminating edge (6). The invention also relates to a method for producing an eye socket covering grid (1). A negative mold is produced by using individual patient data, and a prefabricated blank piece with first and second elongated recesses (5, 8, 9) is then placed on the negative mold. The blank piece is then adapted to the negative mold by applying force/pressure and/or heat, and the molded completed eye socket covering grid (1) is removed/separated from the negative mold.
