Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote terminals are connected to battery terminals to enable jump-starting, then ease of operation is improved, but vulnerability to electronic tampering increases
Solution Approach 1:
A control system acts as an intermediary between the remote terminals and battery terminals, managing current flow authorization. The control system receives signals from remote terminals, verifies authorization, and controls the connection to battery terminals through switches, preventing unauthorized access while enabling legitimate jump-starting operations
Solution Approach 2:
The system implements feedback mechanisms where sensors detect current flow direction and magnitude, and the control system responds by authorizing or denying access, activating alarms, or disconnecting terminals. This closed-loop control ensures that any attempt at electronic tampering is detected and responded to appropriately
2Ease of operation
If battery terminals are accessible for jump-starting, then ease of operation is improved, but risk of unauthorized discharging increases
Solution Approach 1:
The control system serves as an intermediary that mediates all access requests to battery terminals. It evaluates whether discharging is authorized based on sensor inputs and control logic, then selectively enables or disables current flow through switches, preventing unauthorized discharging while maintaining accessibility for legitimate operations
Solution Approach 2:
The system performs preliminary authorization checks before allowing current flow to the battery. Sensors detect connection attempts in advance, the control system verifies authorization status, and only then permits current flow through controlled switches, preventing unauthorized access before it can cause damage
3Reliability
If electronic circuits are added to protect from voltage spikes, then reliability is improved, but device complexity increases
Solution Approach 1:
Protective electronic circuits are introduced as intermediary components between the remote terminals and battery terminals. These circuits include voltage regulation elements and protection devices that automatically activate when voltage anomalies are detected, shielding the battery from voltage spikes while integrating seamlessly into the existing terminal architecture
Solution Approach 2:
The electronic protection circuits provide beforehand cushioning by being pre-installed in the circuit path between remote and battery terminals. When voltage spikes occur during jump-starting or tampering attempts, these circuits immediately activate to clamp or regulate voltage, protecting the battery from damage before the spike can cause harm
