Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional applicators with mechanical mechanisms are used to insert microprobe arrays, then sufficient insertion force can be achieved, but excessive mechanical force is required which may damage skin tissue

Engineering Contradiction:

Improveinsertion forceVSAvoidskin tissue damage

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent applies vibration to the microprobe array during insertion to reduce the mechanical force required. The vibration mechanism oscillates the probes at high frequency, which facilitates tissue penetration by exploiting the viscoelastic properties of skin, thereby reducing the peak force needed and minimizing tissue damage while maintaining effective insertion capability.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent changes the physical state and parameters of the insertion process by introducing vibrational motion and controlling insertion speed dynamically. By adjusting vibration frequency, amplitude, and insertion velocity, the system optimizes the balance between achieving sufficient penetration force and minimizing harmful effects on skin tissue.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If conventional applicators with fixed mechanical mechanisms are used, then consistent force application can be achieved, but adaptability to individual skin characteristics is lost

Engineering Contradiction:

Improveforce application consistencyVSAvoidadaptability to skin characteristics

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static, fixed mechanical mechanisms to dynamic, adjustable systems. The applicator incorporates controllable vibration parameters (frequency, amplitude, duration) and adjustable insertion speeds that can be modified in real-time based on skin characteristics, user feedback, and insertion progress, enabling both consistency and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms including force sensors, vibration sensors, and potentially optical or electrical sensors that monitor insertion progress and skin response. This feedback is used to dynamically adjust vibration parameters and insertion force to maintain optimal performance across different skin types and conditions while ensuring consistent insertion outcomes.

Inventive Principle:

Principle #23Feedback

3Force

If microprobe arrays with sub-10-micron tips and length below 1 mm are used, then insertion force requirement is reduced, but precision in force control and placement is increased

Engineering Contradiction:

Improveinsertion force requirementVSAvoidforce control precision

Core Design Contradiction:

ForceVSManufacturing precision

Solution Approach 1:

The patent replaces purely mechanical force application systems with a hybrid system that incorporates vibration (mechanical oscillation) and electronically controlled actuation. This substitution allows for more precise control of the insertion process through electronic feedback loops that can modulate vibration parameters and apply controlled mechanical forces, achieving the required precision for sub-10-micron tip placement with reduced overall force requirements.
