Camera Ventilation Tubing for Environment Test Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capturing devices for environment test apparatuses face durability issues due to exposure to harsh temperature and humidity conditions, leading to early camera damage and reduced operational lifespan.
Innovation Solution
An image-capturing device with a camera positioned at the tip-end of a ventilation space, surrounded by a heat-resistant and insulating outer tubular member, and an air blower that blows fresh air directly to the camera through a dedicated ventilation path, preventing mixing with heated air and maintaining a stable environment for the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is disposed in the test chamber to capture images, then the image capturing function is achieved, but the camera durability decreases due to exposure to harsh temperature and humidity environments
Solution Approach 1:
The device is divided into two distinct spaces: a first ventilation space (inner tubular member) that exposes the camera to the harsh test chamber environment for image capturing, and a second ventilation space (outer tubular member) that houses the camera in a protected, temperature-controlled zone. This segmentation allows the camera to simultaneously perform its imaging function while being shielded from extreme conditions.
Solution Approach 2:
The outer tubular member acts as an intermediary protective structure between the harsh test chamber environment and the camera. It creates a buffer zone that supplies fresh air to the camera, preventing direct exposure to high temperatures and humidity while still allowing the camera to capture images of the test chamber interior.
2Temperature
If air tubes for air supply and air exhaust are connected to the camera housing to supply dry air, then temperature control is attempted, but fresh air and heated air mix and cannot cover the camera periphery
Solution Approach 1:
The ventilation system is segmented into two separate tubular members: the inner tubular member for air supply and the outer tubular member for air exhaust. This segmentation creates distinct airflow paths that prevent mixing of fresh air and heated air, ensuring that fresh air effectively reaches and covers the camera periphery.
Solution Approach 2:
The design transitions from a single-space ventilation approach to a two-dimensional concentric tubular structure. The inner and outer tubular members create separate airflow channels in different spatial dimensions, allowing independent control of air supply and exhaust paths without interference or mixing.
3Ease of operation
If the camera is exposed to high temperature or low temperature environments for image capturing, then the monitoring function is achieved, but the temperature exceeds the camera's usable range causing damage
Solution Approach 1:
The outer tubular member serves as an intermediary protective barrier that filters and conditions the air before it reaches the camera. It supplies fresh air from the test chamber environment to the camera while blocking harmful extreme temperatures and humidity, allowing the camera to operate within its usable temperature range while still monitoring the harsh environment.
Solution Approach 2:
Different regions of the device have different environmental qualities: the inner tubular member exposes the camera to the harsh test chamber environment for monitoring purposes, while the outer tubular member creates a locally controlled, milder microenvironment around the camera that maintains temperatures within the camera's usable range.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the camera from harsh conditions, reducing the risk of damage and extending its operational lifespan by ensuring fresh air is consistently blown to the camera, maintaining it within a usable temperature and humidity range.
Implementation Method 1
Air is blown toward the camera by the air blower via one of the first ventilation space and the second ventilation space, and is exhausted via the other of the first ventilation space and the second ventilation space.
Implementation Method 2
an outer tubular member configured to cover the inner tubular member
