Solution Overview

Problem

Existing perimeter security camera-equipped vehicles face detection performance degradation due to fog or ice formation during cold seasons, which can be prevented by pre-operating heaters, but this consumes significant battery power.

Innovation Solution

A moving body equipped with detection units, heating units, and a power receiving unit, where the control unit manages the heating units to operate only when powered by an external supply, preventing unnecessary power consumption and ensuring detection performance without depleting stored power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the heater is operated in advance during parking before traveling to prevent fog or ice, then the detection performance of the sensor is improved, but the stored power of the in-vehicle battery is consumed

Engineering Contradiction:
Improvedetection performanceVSAvoidstored power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The heater is operated in advance during parking before traveling to prevent fog or ice formation on the window portion, ensuring clear sensor detection. The control unit determines whether to operate the heater based on stored power level, outdoor temperature, and humidity conditions, performing the heating action preliminarily before the vehicle is needed for travel.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit changes the operational parameters of the heater based on detected conditions (stored power level, outdoor temperature, humidity). When stored power is sufficient and conditions favor fog/ice formation, the heater is operated; when stored power is low or conditions are unfavorable, the heater operation is canceled or adjusted, thus adapting the system behavior to current parameters.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If the heater is not operated to save stored power, then power consumption is reduced, but fog or ice degrades the detection performance of the sensor

Engineering Contradiction:
Improvestored power conservationVSAvoiddetection performance
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The control unit continuously monitors stored power level, outdoor temperature, and humidity conditions, and uses this feedback to determine whether to operate the heater. This feedback mechanism allows the system to make informed decisions about heater operation, balancing power conservation with detection performance requirements based on real-time conditions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Instead of always operating the heater or never operating it, the system applies partial action by operating the heater only under specific conditions (when stored power is sufficient and fog/ice risk is high). This selective operation achieves sufficient prevention of fog/ice formation without the excessive power consumption of continuous operation.

Inventive Principle:
Principle #16Partial or excessive action
