Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a large charging current is used to charge the battery, then the charging time is reduced, but the circuit elements of the charger may be thermally damaged
Solution Approach 1:
The patent implements dynamic adjustment of charging current by the adaptor based on real-time temperature monitoring. The controller dynamically changes the charging current from a first current to a second current according to temperature conditions, transforming the static charging process into a dynamic adaptive process that resolves the contradiction between fast charging and thermal safety
Solution Approach 2:
The patent employs a feedback mechanism where the sensor continuously monitors temperature and feeds this information to the controller. The controller then adjusts the charging current accordingly, creating a closed-loop control system that automatically balances charging speed and thermal protection based on real-time conditions
2Reliability
If the charging current is reduced to protect circuit elements, then thermal damage is prevented, but the charging efficiency decreases
Solution Approach 1:
The patent changes the charging current parameter dynamically based on temperature conditions. The adaptor switches between different current levels (first current and second current) according to thermal status, allowing the system to maintain high charging efficiency when safe and reduce current only when necessary for thermal protection
Solution Approach 2:
The patent applies partial action by using high charging current only when temperature conditions permit, and reducing to lower current only when thermal protection is needed. This partial application of maximum current resolves the contradiction by avoiding excessive current while maintaining sufficient charging speed during safe operating conditions
