Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the emergency jump starter uses clips that generate magnetism when energized, then the clips can be easily connected to the battery terminals, but the clips may be adsorbed together for a long time causing short circuit and damage to internal circuit
Solution Approach 1:
The patent applies the demagnetization function to convert the harmful magnetic adsorption effect into a beneficial automatic separation mechanism. The controller activates the demagnetization function after jump-start completion to actively eliminate residual magnetism in the clips, transforming the potential short-circuit hazard into a safety feature that ensures automatic clip separation and prevents internal circuit damage.
Solution Approach 2:
The patent implements a feedback control mechanism where the controller monitors the jump-start process and automatically activates the demagnetization function after operation completion. This closed-loop feedback ensures that the clips are actively demagnetized at the appropriate time, preventing prolonged magnetic adsorption and potential short circuits without requiring manual user intervention.
2Device complexity
If the emergency jump starter lacks protection mechanisms for lithium battery charging and discharging, then the device structure can be simpler, but it is easy to damage the emergency jump starter itself
Solution Approach 1:
The patent applies preliminary action by implementing protection mechanisms that proactively monitor and control battery charging and discharging processes before damage can occur. The controller continuously detects battery parameters and preemptively activates protection functions when abnormal conditions are detected, preventing battery damage before it happens rather than responding after failure occurs.
Solution Approach 2:
The patent implements real-time feedback control through the controller that continuously monitors battery charging and discharging parameters. When abnormal conditions are detected, the controller automatically activates protection mechanisms to adjust or terminate the charging/discharging process, ensuring battery safety through continuous monitoring and active response to changing conditions.
3Device complexity
If the emergency jump starter lacks reaction mechanisms under unfavorable situations, then the device structure can be simpler, but it cannot cope with temperature changes, lithium battery bulging, or burning
Solution Approach 1:
The patent applies preliminary action by pre-equipping the device with multiple detection modules (temperature, bulge, etc.) and protection functions that are ready to activate before actual damage occurs. These mechanisms are designed to detect unfavorable conditions early and preemptively activate appropriate protection measures, enabling the device to cope with various environmental challenges without requiring complex structural modifications.
Solution Approach 2:
The patent implements multi-functionality through a universal controller that manages multiple detection modules and protection functions. The controller serves multiple purposes: monitoring temperature, detecting battery bulge, controlling demagnetization, and managing charging/discharging protection. This universal control architecture enables the device to respond to various unfavorable conditions with a single integrated system rather than requiring separate specialized mechanisms for each condition.
