Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing osteosynthesis implants are complicated to handle and attach to separated bone segments due to the need for precise plastic deformation, requiring multiple bending operations and intricate adaptation to the bone contour.
Innovation Solution
The implant features elastically deformable snap-on lugs that can be temporarily deformed to snap onto bone segments with minimal deformation, eliminating the need for intricate adaptation and reducing the number of working steps, with a reinforced lattice-shaped securing region and variable pretension to accommodate individual bone tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the implant uses plastic deformation to adapt clips to bone contour, then the implant can be customized to fit bone segments, but the handling and attachment process becomes complicated requiring multiple bending operations
Solution Approach 1:
The patent changes the deformation mechanism from plastic to elastic. The projections are designed to be elastically deformable, allowing them to be temporarily deformed during attachment and then return to their original shape. This eliminates the need for multiple bending operations while maintaining adaptability to bone contours.
Solution Approach 2:
The patent introduces dynamic elasticity to the projections, making them flexible during the attachment process. The projections can be deformed elastically to fit around bone segments and then maintain their position through elastic recovery, transforming a static plastic deformation process into a dynamic elastic one that is easier to control and reverse if needed.
2Manufacturing precision
If the implant requires precise plastic deformation for proper fitting, then the final fit can be accurate, but the number of working steps increases requiring repeated application and adjustment
Solution Approach 1:
The patent changes the deformation parameter from irreversible plastic deformation to reversible elastic deformation. This allows the projections to be temporarily deformed to the required precision during attachment, then maintain that precision through elastic memory without requiring repeated adjustments. The elastic properties enable single-step attachment with accurate fitting.
Solution Approach 2:
The patent incorporates preliminary elastic deformation capability into the projection design itself. The projections are pre-designed with elastic properties that allow them to be deformed to the correct shape during a single attachment operation, eliminating the need for multiple subsequent adjustments. The elastic deformation is performed once and maintains precision without requiring repeated application and adjustment cycles.
3Stability of the object's composition
If the implant uses integrated clips attached to support web, then the structure is compact and integrally formed, but the clips cannot be easily deformed without affecting the entire implant
Solution Approach 1:
The patent applies local quality by making only the projections elastically deformable while keeping the securing region rigid. The projections are designed with specific elastic properties that allow localized deformation independent of the support web, while the securing region maintains its structural integrity and rigidity for stable fixation to bone segments.
Solution Approach 2:
The patent segments the implant into functionally distinct parts: a rigid securing region for stable attachment and elastically deformable projections for adaptation. This segmentation allows the projections to be deformed independently without affecting the structural integrity of the securing region, resolving the contradiction between overall structural stability and local deformability.
4Strength
If the implant is designed with reinforced securing region, then the fixation is robust and stable, but the overall implant becomes less flexible for deformation
Solution Approach 1:
The patent applies local quality by concentrating reinforcement in the securing region while keeping the projections thin and flexible. The securing region has increased thickness and structural complexity (lattice structure with multiple webs) for strong fixation, while the projections maintain minimal thickness for easy elastic deformation. This localized differentiation resolves the contradiction between overall flexibility and local strength.
Solution Approach 2:
The patent segments the implant into a rigid, reinforced securing region for strong fixation and flexible, thin projections for adaptability. The securing region contains the lattice structure with multiple webs and holes for bone screw attachment, providing robust strength. The projections are separated as independent elastically deformable elements, allowing flexibility without compromising the strength of the secured region.

Function Achieved in This Case
