Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If technicians use existing electrical test devices to measure voltage and continuity, then basic diagnostic measurements can be performed, but additional diagnostic testing capabilities are not supported
Solution Approach 1:
The patent applies universality by designing a diagnostic probe system that can perform multiple diagnostic functions (voltage measurement, continuity testing, PWM signal measurement, current measurement) through a single integrated apparatus. The probe includes multiple probe elements that can be selectively engaged to provide different measurement capabilities, eliminating the need for multiple separate test devices and expanding the versatility of the base electrical test device.
2Adaptability or versatility
If technicians acquire additional expensive, bulky test devices to perform advanced diagnostic tests, then comprehensive diagnostic capabilities are achieved, but storage space and cost increase
Solution Approach 1:
The patent applies the nested doll principle by designing a compact diagnostic probe that can be attached to or integrated with an existing electrical test device. The probe contains multiple measurement circuits and probe elements nested within a small form factor housing, allowing comprehensive diagnostic capabilities to be added without requiring separate bulky devices. The entire diagnostic system fits within the footprint of the base test device, minimizing additional storage space requirements.
3Adaptability or versatility
If existing electrical test devices are used for basic measurements, then simple voltage and continuity diagnostics are possible, but current measurement and PWM signal measurement capabilities are missing
Solution Approach 1:
The patent applies dynamics by incorporating selectable input mechanisms that allow the diagnostic probe to dynamically switch between different measurement modes (voltage, continuity, current, PWM). The probe can be configured for different measurement types through user-selectable switches or buttons, enabling the device to adapt its measurement capabilities based on the diagnostic task at hand. This dynamic reconfiguration capability provides multiple measurement types without requiring separate fixed-function devices.
