Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing electrode leads are designed to be maximum in length to accommodate all size patients, then all patient sizes can be accommodated, but excess wires around smaller patients cause discomfort and safety hazards
Solution Approach 1:
The electrode lead incorporates a telescopic mechanism that allows the lead length to be dynamically adjusted. The telescopic sections can extend to accommodate larger patients and retract to minimize excess wire for smaller patients, eliminating discomfort and safety hazards while maintaining adaptability across all patient sizes.
Solution Approach 2:
The electrode lead contains nested telescopic sections where one lead segment is inserted within another. When the lead is not fully extended, the inner segments are retracted into outer segments, creating a compact configuration that eliminates excess wire for smaller patients while allowing full extension when needed for larger patients.
2Adaptability or versatility
If existing electrode leads are designed to be maximum in length to accommodate all size patients, then all patient sizes can be accommodated, but it becomes difficult to keep wires from tangling and maintain appropriate application
Solution Approach 1:
The telescopic lead allows operators to dynamically adjust the lead length to match the specific patient size, minimizing excess wire that would otherwise tangle. This dynamic adjustment simplifies the application process and wire management while maintaining the ability to accommodate all patient sizes.
Solution Approach 2:
The lead length parameter can be changed to match the specific requirements of each patient. By adjusting the lead length to the minimum necessary length rather than using a fixed maximum length, the system reduces wire tangling and simplifies application while still accommodating all patient sizes through appropriate length selection.
3Measurement precision
If conventional electrode placement procedures are used, then standard electrode positions can be achieved, but application and calibration procedures are cumbersome and prone to human errors
Solution Approach 1:
The electrode padset is pre-configured with conductive pads arranged in the correct anatomical positions on a flexible substrate. This preliminary arrangement eliminates the need for complex manual placement and calibration procedures during application, reducing human errors while maintaining measurement precision. The pre-configured padset simply needs to be applied to the patient's body.
Solution Approach 2:
The invention combines multiple electrode pads, connection leads, and positioning features into a single integrated padset unit. This merging of components simplifies the application process by eliminating separate calibration steps and reducing the complexity of handling multiple separate electrodes, while maintaining accurate signal acquisition through the integrated design.
