Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired fracture reduction robot is used, then power can be continuously supplied to driving members, but electric wires interfere with the surgical procedure and may contact the bone being reduced
Solution Approach 1:
The patent removes the power source (battery) from the external control unit and integrates it into the portable actuator itself. This extraction of the harmful element (external power wires) eliminates the interference problem while maintaining continuous power supply through the integrated battery pack in the actuator.
Solution Approach 2:
The patent replaces the mechanical/wired power transmission system with a wireless power system using an integrated battery. The actuator becomes a self-powered wireless unit that communicates with the control unit through wireless communication, eliminating the need for physical electric wires connecting to the bone reduction area.
2Power
If a bulky robot with wired driving components is used, then driving power can be ensured, but the robot size becomes too large for surgical room requirements
Solution Approach 1:
The patent divides the fracture reduction robot into separate functional modules: a portable actuator with integrated battery and motor, a separate control unit, and interchangeable variable legs. This segmentation allows the main robot body to be compact while the power source is distributed to where it's needed in the portable actuator.
Solution Approach 2:
The patent creates a dynamic system where the portable actuator can be moved and repositioned freely without being constrained by fixed power wires. The variable legs can be interchanged based on surgical needs, and the actuator adapts to different positions and orientations during the procedure, providing flexibility without increasing overall system volume.
3Measurement precision
If surgeons manually perform bone traction and positioning, then precise control can be achieved, but excessive physical strain is applied to surgeons and multiple surgeons are required
Solution Approach 1:
The patent implements a self-powered portable actuator that autonomously performs the traction and positioning functions. The actuator with integrated battery and motor automatically adjusts the variable legs to achieve precise bone alignment without requiring surgeons to manually hold or adjust heavy equipment, eliminating physical strain while maintaining precision through controlled actuation.
Solution Approach 2:
This principle doesn't apply to this patent as it relates to chemical oxidation processes, which are not relevant to the mechanical and wireless control system described in the fracture reduction robot.
4Ease of manufacture
If a fracture table is used for traction, then simple setup is achieved, but accurate positioning of bone fragments and force measurement are impossible
Solution Approach 1:
The patent creates a multi-functional portable actuator that combines the simplicity of a fixed device with the precision and measurement capabilities of a complex robotic system. The actuator serves multiple functions: providing controlled traction, achieving accurate positioning through programmable movement, measuring forces through sensors, and communicating wirelessly with the control unit, all in a compact portable design that is easier to set up than traditional fracture tables.

AI summary
Provided is a fracture reduction robot including a fracture reduction part having a plurality of ring frames for surrounding a fractured area of a patient and at least one or more struts located between the ring frames to adjust a distance between the ring frames and a wireless driving part connected to any one of the ring frames to transmit power for adjusting the distance to the struts, whereby during fracture reduction surgery, interferences with electric wires can be avoided.
