Innovation Solution
A dual-battery system with an activation device that includes a circuit-breaker unit switchable between open and closed states, controlled by a processor unit comparing voltage signals from the ignition lock circuit to ensure energy supply from the starter battery even when the power battery is depleted, using a signal unit to generate and convey voltage signals and a monitoring unit to detect changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circuit-breaker is used to control energy flow in a dual-battery system, then energy distribution can be regulated, but the system fails when the power battery is depleted and requires activation current that consumes battery energy
Solution Approach 1:
The circuit-breaker is designed to activate automatically based on voltage signal monitoring without requiring external activation current. The monitoring unit detects voltage drops indicating power battery depletion and triggers the circuit-breaker closure autonomously, eliminating the need for separate activation energy supply.
Solution Approach 2:
The patent replaces traditional electromechanical circuit-breaker activation with an electronic monitoring and control system. The processor unit monitors voltage signals and controls the circuit-breaker closure electronically, eliminating the need for mechanical activation mechanisms that consume battery energy.
2Adaptability or versatility
If multiple components are used for monitoring and controlling the dual-battery system, then system functionality is enhanced, but system complexity and sensitivity to malfunctions increase
Solution Approach 1:
The patent combines the signal generation, voltage monitoring, processing, and circuit-breaker control functions into an integrated activation device. This consolidation reduces the number of separate components while maintaining full system functionality, thereby reducing complexity and potential failure points.
Solution Approach 2:
The activation device performs multiple functions: generating voltage signals, monitoring battery voltage, processing signals to detect depletion conditions, and controlling circuit-breaker activation. This multi-functional design eliminates the need for separate dedicated components for each function.
