Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measurement items are combined in a fixed-type integrated device, then measurement functionality is improved, but device portability deteriorates
Solution Approach 1:
The device is divided into a handheld detection unit and a separate battery pack, allowing the detection functions to be portable while the battery pack provides power and can be replaced. This segmentation enables comprehensive measurement capabilities without making the handheld unit bulky.
Solution Approach 2:
The detection device is designed with universal compatibility to detect multiple battery types (lead-acid, lithium-ion, nickel-cadmium) and perform various measurement functions (voltage, current, temperature, impedance) through a single integrated handheld unit, eliminating the need for multiple specialized devices.
2Device complexity
If a simple detection device is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The device separates detection functions into a simple handheld unit and places complex measurement capabilities in the battery pack, allowing the handheld unit to remain simple while maintaining high measurement precision through specialized sensors and processing in the battery pack.
Solution Approach 2:
The battery pack acts as an intermediary that handles complex measurement tasks (current measurement, impedance analysis) while the handheld unit provides simple user interaction and display, distributing complexity across multiple components.
