Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for observing objects in high-temperature environments, such as paint drying furnaces, face challenges in capturing high-definition images of moving objects due to heat limitations and the inability to continuously observe distant or inner areas, leading to blurred images and limited usability.
Innovation Solution
A heat-resistant imaging camera with a heat-insulated outer case and cold storage material packs that absorb heat, combined with an internal battery and LED lighting semiconductors, allowing for continuous high-definition imaging without external power and in high-temperature environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an observation window is provided in the outer wall of the high temperature drying furnace to observe the moving object, then the observation can be performed from the outside, but only the range visible from the observation window or the outer side of the moving object can be observed, making it difficult to image distant places or capture high-definition images through the stationary window
Solution Approach 1:
The imaging device is mounted on a moving device that moves along with the painted object through the drying furnace, enabling dynamic positioning and continuous tracking of the object throughout the entire process, thereby capturing high-definition images from multiple angles and positions that would be inaccessible to a stationary observation window
Solution Approach 2:
A moving device serves as an intermediary carrier, transporting the imaging device along with the painted object through the drying furnace, enabling flexible positioning and close-proximity imaging that overcomes the limitations of fixed observation windows
2Ease of operation
If a cable is used to supply power and transmit images from outside the vessel to the automatic inspection device, then the device can receive power and transmit images, but the heat resistance of the cable limits the usable high temperature field to a relatively low temperature
Solution Approach 1:
The imaging device carries its own power supply (battery) and performs autonomous operation within the high-temperature drying furnace, eliminating the need for heat-sensitive external cables and enabling operation in the full high-temperature range required for paint drying
Solution Approach 2:
The power supply function is extracted from the external cable system and integrated directly into the imaging device as an internal battery, removing the thermal bottleneck imposed by cable heat resistance and enabling operation in high-temperature environments
3Productivity
If the imaging device is mounted on a moving device that moves in a high temperature drying furnace reaching 200°C, then continuous high-definition imaging can be achieved, but the device must withstand high temperatures that would normally damage conventional imaging equipment
Solution Approach 1:
Cold storage material packs utilizing phase change (melting from solid to liquid at specific temperature) absorb intrusive heat through melting latent heat, maintaining a stable temperature environment for the camera and enabling continuous high-definition imaging in the high-temperature drying furnace
Solution Approach 2:
The housing structure employs composite thermal management combining heat insulator material and cold storage material packs, creating a multi-layer thermal protection system that blocks and absorbs heat to protect the camera from high-temperature damage while enabling continuous operation

AI summary
Provided is a heat-resistant imaging camera configured to move in a high temperature furnace and configured to capture high-definition images of the outer side or the inner side of a painted object passing in a high temperature drying furnace. Heat insulators (13a to 13f) are attached to all inner surfaces of an outer case (10) of a heat-resistant imaging camera (1) except a double glass window (21), and cold storage material packs (15a to 15e) are disposed inward of the heat insulators (13a to 13f) in layers so as to cover around a camera (2). Intrusive heat is absorbed by melting latent heat when the cold storage material packs (15a to 15e) are melted and changed in phase from a solid to a liquid at a specific temperature or higher, thereby ensuring heat resistance that maintains the camera (2) at a safely operatable temperature.
