Solution Overview

Problem

Current imaging apparatuses in vehicle utilization and monitoring systems face challenges in reducing power consumption while maintaining effective image capture and authentication processes.

Innovation Solution

The implementation of an imaging apparatus with multiple operation modes, including a low-power mode for initial detection and a high-resolution mode for authentication, allows for efficient power management by switching between modes based on detected activity, thereby reducing overall power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the imaging unit operates in high-resolution mode to generate captured images for authentication, then image quality and authentication reliability are improved, but power consumption increases

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The imaging unit dynamically switches between a first operation mode (low-power mode without captured image generation) and a second operation mode (high-resolution mode with captured image generation for authentication). The operation mode setting section controls this switching based on whether authentication is required, allowing the system to adapt power consumption to actual needs while maintaining authentication reliability when necessary

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the imaging unit by selecting different operation modes. In the first mode, parameters are set to minimize power consumption (no captured image generation). In the second mode, parameters are adjusted to generate high-quality captured images for authentication. This parameter switching resolves the contradiction by allowing optimal performance in each state

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the imaging unit continuously generates captured images for authentication, then authentication processing reliability is improved, but power consumption increases

Engineering Contradiction:
Improveauthentication processing reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

Instead of continuous operation, the imaging unit performs captured image generation periodically or on-demand based on authentication requirements. The operation mode setting section switches to the second operation mode only when authentication is needed, and returns to the first operation mode otherwise, creating a periodic action pattern that maintains reliability while reducing overall power consumption

Inventive Principle:
Principle #19Periodic action
