Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone plate guiding systems are cumbersome and prone to misalignment, requiring intricate attachment mechanisms that complicate surgical procedures.
Innovation Solution
A bone-fixation system comprising a bone plate with a recessed section and an aiming block with an extension that aligns with the plate's holes, along with a joystick for secure positioning, allowing for precise alignment and easy attachment of the aiming block to the bone plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intricate attachment mechanisms are used to secure the aiming block to the bone plate, then the aiming block can be firmly fixed, but the surgical procedure becomes more complex and difficult to perform
Solution Approach 1:
The attachment mechanism is merged with the bone plate structure itself. The bone plate includes integrated attachment features such as slots, holes, or geometric shapes that directly receive and secure the aiming block, eliminating the need for separate intricate attachment mechanisms. This integration maintains firm fixation while simplifying the overall system and surgical procedure.
Solution Approach 2:
The bone plate is designed to be self-sufficient by incorporating built-in attachment features that automatically secure the aiming block upon placement. The aiming block interfaces with these pre-integrated features through simple alignment and engagement, allowing the system to secure itself without requiring complex external attachment devices or multiple surgical steps.
2Measurement precision
If complex instruments are used for initial placement of the aiming block, then precise positioning can be achieved, but the surgical procedure requires more cumbersome tools and increases operational difficulty
Solution Approach 1:
The bone plate is pre-configured with attachment features and geometric cues during manufacturing that guide the aiming block into the correct position. These pre-integrated features establish alignment and positioning requirements before surgery, allowing surgeons to simply match the aiming block with the corresponding features on the plate, thereby achieving precise positioning with minimal instrumentation and operational complexity.
3Reliability
If the aiming block design requires multiple components and intricate mechanisms, then secure fixation can be achieved, but the number of surgical steps and time required increases
Solution Approach 1:
Multiple functions are merged into a single integrated design. The bone plate combines structural support, attachment mechanisms, and alignment features into one component that works with a simple aiming block. This integration secures fixation reliability while reducing the number of separate components and surgical steps required, thereby improving procedural efficiency.
Solution Approach 2:
The system is segmented into two main functional parts: the bone plate with integrated attachment features and the aiming block with corresponding interface elements. This segmentation allows each component to be optimized independently while maintaining simple, direct interaction between them, reducing the overall number of components and surgical steps compared to systems with multiple separate attachment mechanisms.
