Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional negative pressure suction is used at a single fixed point, then the surgery is simple to perform, but uneven skin development occurs due to variation in depth between liposuctions
Solution Approach 1:
The robotic arm enables dynamic, multi-directional movement of the suction tube, allowing the surgeon to access different depths and angles of fat deposits systematically. This dynamic positioning capability ensures uniform fat removal at varying depths while maintaining skin flatness, resolving the contradiction between surgical precision and operational simplicity.
Solution Approach 2:
The invention transitions from single-point, fixed-depth suction to multi-dimensional liposuction by enabling the suction tube to operate at multiple depths and angles simultaneously. This dimensional expansion allows comprehensive fat removal throughout the adipose layer while maintaining uniform skin surface, addressing the skin flatness issue without excessive surgical complexity.
2Productivity
If ultrasonic energy is increased for fat disintegration, then fat removal efficiency is improved, but the probe temperature rises and may burn the skin
Solution Approach 1:
The invention extracts the ultrasonic probe from direct contact with the skin surface by introducing a separate negative pressure suction tube. The ultrasonic energy is applied subcutaneously to disintegrate fat, while the suction tube removes fat deposits through negative pressure without requiring high-temperature probes near the skin surface, thereby eliminating skin burn risk while maintaining fat removal efficiency.
Solution Approach 2:
The negative pressure suction system acts as an intermediary mechanism that separates the fat disintegration function (ultrasonic) from the fat removal function (suction). This intermediary approach allows ultrasonic energy to be applied at safe temperatures for fat breakdown, while the suction tube handles the actual fat extraction, preventing direct heat transfer to the skin and avoiding burns.
3Reliability
If reciprocating liposuction movement is performed manually during massive liposuction, then the surgeon can control the process, but considerable physical strength is required resulting in surgeon fatigue
Solution Approach 1:
The robotic system performs the physically demanding reciprocating movement and positioning tasks autonomously, freeing the surgeon from exerting considerable physical strength. The surgeon maintains control through electronic interfaces, allowing the system to serve itself in performing the mechanical work while the surgeon oversees the surgical decisions, thereby eliminating fatigue while preserving surgical control.
Solution Approach 2:
The invention replaces the surgeon's manual mechanical effort with an automated robotic mechanical system. The robotic arm executes the reciprocating liposuction movements with precise control, substituting the surgeon's physical strength with motorized actuation. This substitution eliminates surgeon fatigue from manual manipulation while maintaining reliable surgical control through electronic interfaces.
