Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current interconnection devices are used, then the procedure can be completed, but the invasiveness of the procedure increases and implant integrity is compromised
Solution Approach 1:
The connector element incorporates a flexibly deformable wall that can elastically deform to transition between configurations. This flexible wall allows the device to adapt to component insertion while maintaining structural integrity, reducing invasiveness during implantation while ensuring reliable connection.
Solution Approach 2:
The connector element is designed with a first wall capable of transitioning between a first configuration and a second configuration. This dynamic structure allows the device to change shape during implantation to facilitate component insertion, then lock into a secure configuration to maintain implant integrity.
2Ease of operation
If current interconnection devices are used, then the components can be connected, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The retainer element automatically engages with the connector element to maintain the first wall in the second configuration. This self-retaining mechanism eliminates the need for additional fastening steps or complex assembly procedures, improving ease of operation while managing device complexity through intelligent design.
Solution Approach 2:
The retainer element acts as an intermediary between the connector element and the component being secured. It cooperates with the connector element to maintain the wall configuration, providing a simple interface that facilitates easy assembly without requiring complex direct connections.

Function Achieved in This Case
The solution provides a stable and secure interconnection of spinal implant components, enhancing the integrity of the implant assembly and reducing invasiveness, thereby improving patient outcomes and treatment efficacy for spinal disorders.
Implementation Method 1
A flexibly deformable wall encloses the passage but for one section including an opening. The wall is capable of transitioning from a first configuration arranged to transversely receive the portion of the component and a second configuration arranged to lock the portion of the component in the passage.

AI summary
A spinal fixation system including an interconnection device is provided. The interconnection device comprises a connector element including a passage structured to receive a component of the spinal fixation system therein. The passage is at least partially bound by a first wall portion and a second wall portion, wherein the first wall portion is movable between a first position to receive the component and a second position to restrain the component in the passage. The device further includes a retainer element which holds the first wall portion in the second position in order to lock the component in the passage.
