Solution Overview

Problem

Existing methods for testing cameras in high and low temperature environments only verify if a camera can operate after being exposed, but not if it can function normally in real-time within these conditions, leading to a need for a device that can detect camera performance in extreme temperatures effectively.

Innovation Solution

A device comprising a high and low temperature cabinet, a parallel light tube component, a test box, and positioning tables, along with an image acquisition system, which allows for real-time performance testing of cameras by adjusting temperatures and positioning to ensure accurate results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a camera is placed in a thermostatic chamber for temperature testing, then the camera can be exposed to extreme temperatures, but the testing cannot verify real-time operation performance in those temperature environments

Engineering Contradiction:
Improvecamera operation reliability in extreme temperaturesVSAvoidreal-time performance detection accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent introduces a transparent isolation chamber as an intermediary between the thermostatic chamber and the camera testing environment. This isolation chamber can be filled with temperature-controlled gas, allowing the camera to be tested in real-time under extreme temperature conditions while maintaining optical transparency for imaging. The intermediary structure enables both temperature exposure and real-time performance verification simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the camera is taken out from the thermostatic chamber for testing, then the camera can be tested at room temperature, but the test cannot verify whether the camera operates normally in the high and low temperature environments

Engineering Contradiction:
Improvetesting convenienceVSAvoidcamera performance verification in extreme temperatures
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The transparent isolation chamber serves as a mediator that allows the camera to remain inside the thermostatic chamber while enabling external observation and testing. This eliminates the need to repeatedly remove and reinsert the camera, maintaining both operational convenience and reliable verification of extreme temperature performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The isolation chamber enables continuous real-time testing of the camera under extreme temperature conditions without interruption. The camera operates continuously in the temperature environment while performance is monitored in real-time, eliminating the stop-start nature of traditional testing methods.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If real-time testing of camera in extreme temperatures is implemented, then accurate performance data can be obtained, but the testing system complexity increases

Engineering Contradiction:
Improvecamera performance measurement accuracyVSAvoidtesting system structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The transparent isolation chamber serves multiple functions: it maintains temperature isolation, allows optical transmission for imaging, enables gas filling for temperature control, and provides structural support. This multi-functional design achieves real-time accurate testing without proportionally increasing system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The isolation chamber utilizes transparent materials that are both thermally isolatable and optically transmissive. These flexible transparent structures enable temperature control while maintaining optical access, achieving complex testing requirements through relatively simple material selection.

Inventive Principle:
Principle #30Flexible shells and thin films
