Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized control unit is used to control motorized struts, then the system can be controlled, but the device becomes bulky and cumbersome with safety hazards
Solution Approach 1:
The patent divides the centralized control unit into separate controller modules that are distributed throughout the spatial frame structure. Each controller module independently controls specific strut actuators, eliminating the need for a single bulky centralized unit while maintaining system control capability.
Solution Approach 2:
The control functionality is extracted from a centralized location and distributed to multiple smaller controller modules positioned at different locations within the spatial frame. This extraction reduces the bulkiness and safety hazards associated with a large centralized control unit.
2Extent of automation
If motorized struts are used to automate adjustments, then patient compliance improves, but the device becomes more complex
Solution Approach 1:
The control circuitry is segmented into separate, distributed controller modules rather than a single complex centralized system. Each module handles control for specific actuators, reducing overall system complexity while maintaining automation capability.
Solution Approach 2:
The spatial frame system automatically executes treatment plans without requiring continuous patient intervention. The distributed controllers autonomously manage strut adjustments according to programmed parameters, enabling automation while keeping individual control modules simple and manageable.
3Adaptability or versatility
If complex circuitry is housed within motorized struts, then control is integrated, but manufacturing and sterilization become more difficult
Solution Approach 1:
The control circuitry is segmented into separate controller modules that can be manufactured and sterilized independently from the spatial frame components. This segmentation allows each module to be produced using appropriate manufacturing processes and sterilized without compromising the entire system.
Solution Approach 2:
The control circuitry is extracted from the motorized strut assemblies and placed in separate, dedicated controller modules. This extraction simplifies manufacturing by allowing specialized production processes for each component and facilitates sterilization by isolating electronic elements from the main structural components.

Function Achieved in This Case
The solution provides a compact, safer, and more reliable motorized strut system that reduces patient burden, minimizes errors, and enables finer adjustments for improved bone healing, while maintaining treatment plan compliance.
Implementation Method 1
The coupler of the motorized strut and the coupler of the detachable programmer are arranged and configured as magnetic couplers so that the detachable programmer is magnetically attached to the motorized strut
Data Source
AI summary
A detachable programmer arranged and configured to be selectively coupled to a motorized strut in an automated and/or motorized spatial frame is disclosed. In some examples, a plurality of detachable programmers are provided, one for each of the plurality of motorized struts in the spatial frame. Thus arranged, each of the plurality of detachable programmers can be configured to supply power and/or control the motorized strut to which it is connected to actuate the motorized strut according to a treatment plan negating, or at least minimizing, the need for any complex, sensitive circuitry housed within the motorized strut. In some examples, the detachable programmer is configured to magnetically couple to the motorized strut via a magnetic or bayonet-style connector.
