Solution Overview
Problem
Current treatments for hyperhidrosis, such as medications and ablation therapy, are not entirely effective in providing a non-invasive and efficient solution for reducing excessive sweating, which can lead to physical and emotional side-effects.
Innovation Solution
A microwave-based tissue modification system with a tissue interface module that includes a bio-barrier, vacuum port, and a filter to prevent liquid passage, allowing for the application of microwave energy while maintaining a vacuum to treat excessive sweating by attaching a microwave antenna and cooling element to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is added to prevent liquid passage between chambers, then liquid containment is improved, but device complexity increases
Solution Approach 1:
The filter is integrated within the tissue interface module structure, nested between the applicator chamber and tissue acquisition chamber. This nesting approach allows the filter to perform liquid containment while being part of the overall module architecture rather than a separate external component, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The filter utilizes porous material properties to achieve selective permeability - allowing air and vacuum to pass through while blocking liquid. This material-based solution provides effective liquid containment through the inherent properties of the porous structure itself, eliminating the need for additional mechanical barriers or complex sealing mechanisms.
2Ease of operation
If a variable flow restrictor is added to control air flow, then air flow control is improved, but device complexity increases
Solution Approach 1:
The variable flow restrictor incorporates a flexible element that dynamically adjusts the flow opening size in response to pressure differences between chambers. This dynamic adjustment mechanism allows automatic air flow control based on operating conditions without requiring external actuators or complex control systems, thereby improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The flow restrictor uses the pressure differential that naturally occurs during operation to drive the flexible element and adjust the flow opening. The system self-regulates air flow based on its own operating conditions without requiring external control inputs, providing automatic air flow management with minimal additional complexity.
3Reliability
If an attachment mechanism is added to secure the tissue interface module, then connection reliability is improved, but ease of operation decreases
Solution Approach 1:
The attachment mechanism utilizes magnetic force to create a secure connection between the tissue interface module and the applicator. The magnetic attachment provides reliable connection through attractive force while allowing for relatively easy attachment and detachment through simple approach and separation movements, avoiding complex mechanical interlocking mechanisms.
Solution Approach 2:
The magnetic attachment mechanism replaces traditional mechanical fastening systems (such as screws, clips, or latches) with a magnetic field-based attachment system. This substitution provides secure connection reliability through magnetic attraction while significantly improving ease of operation by eliminating complex mechanical manipulation requirements.
