Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional hypodermic needles are used for medical treatments, then the treatment can be performed, but the insertion and retraction lack precise control leading to pain and infection risks
Solution Approach 1:
The patent replaces traditional mechanical needle insertion systems with a semiconductor-based MEMS actuator system that provides precise electronic control of needle movement, enabling controlled insertion and retraction to minimize pain and infection risk
Solution Approach 2:
The patent changes the control parameters of needle insertion from manual/uncontrolled to electronically controlled with precise depth regulation, allowing optimization of insertion speed and depth to reduce pain and improve safety
2Manufacturing precision
If semiconductor fabrication techniques are integrated to create movable needle systems, then precise control over needle movement is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the needle, actuator, and controller into a single integrated semiconductor device fabricated using MEMS techniques, reducing the number of separate components while maintaining precise control functionality
Solution Approach 2:
The patent creates a multi-functional integrated device that combines needle delivery, actuation, and control capabilities in a single semiconductor structure, enabling precise movement control without proportionally increasing overall device complexity

AI summary
A needle system for penetrating to or passing thought an object or an organ comprising a semiconductor die, one or more needles, wherein the needles move relative to the die using one or more actuators. The actuators are controlled by a controller wherein the controller instruct the needle to penetrate into or to pass through and/or retract from the object or organ. The needle system is used among other treatments for drug delivery, blood extraction, blood analysis, glucose measurements, blood measurements, nerve system stimulus treatment, hair removal, skin lesions coloring or removal or tattoo painting or removal.
