Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the watchband is designed as a simple fixation structure, then the device complexity is low and ease of manufacture is high, but the functionality and versatility are limited
Solution Approach 1:
The patent merges the fixation function and electrical stimulation function into a single integrated watchband structure. The watchband incorporates an electrical stimulation module with electrodes, signal strips, and circuit boards embedded within the band itself, combining mechanical fastening with medical therapeutic functions in one component.
Solution Approach 2:
The watchband is designed to perform multiple functions: mechanical fixation of the bracelet to the wrist, electrical stimulation delivery for gastric control and appetite reduction, physiological parameter monitoring via sensors, and metabolic enhancement. This multi-functional design transforms a simple fixation element into a versatile therapeutic device.
2Adaptability or versatility
If an electrical stimulation module is added to the watchband, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The electrical stimulation components are nested within the watchband structure. The circuit board, signal strip, and electrodes are embedded inside the watchband housing, with only the electrodes making external contact through the band material. This nesting approach consolidates multiple components into a compact integrated unit.
Solution Approach 2:
The watchband incorporates flexible circuit boards and thin film signal strips that can bend and conform to the curved surface of the wrist. These flexible components maintain electrical connectivity while adapting to the wearable form factor, enabling complex functionality within a flexible, form-fitting structure.
3Adaptability or versatility
If the electrode is placed at the end of the watchband, then the electrical stimulation function is achieved, but the structural complexity increases
Solution Approach 1:
The electrode is extracted and positioned at the distal end of the watchband, separate from the main circuit board assembly. This extraction allows the electrode to be optimally positioned for direct skin contact and electrical stimulation delivery, while the main circuitry remains consolidated in the dial assembly, simplifying the overall wiring architecture.
