Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic video cameras face challenges in achieving a stable design while ensuring reliable heat dissipation and easy access to internal components for servicing, as existing designs often compromise on mechanical stability, heat management, and component protection against environmental factors like dust and moisture.
Innovation Solution
The camera body incorporates an inner carrier structure forming a central cooling passage that divides the interior space into a ventilation area open to the environment and a sealed component space, allowing for efficient heat dissipation through convective cooling and providing easy access to electronic components by releasable outer cover elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the camera body is designed with a sealed structure to protect electronic components from environmental factors, then protection against dust and moisture is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The camera body is divided into a sealed component space for electronic components and a separate ventilation space for heat dissipation. The carrier structure creates this segmentation by forming walls that separate these two functional zones, allowing the component space to remain sealed while the ventilation space provides thermal management through controlled airflow.
Solution Approach 2:
The carrier structure acts as an intermediary element between the sealed component space and the ventilation space. It provides thermal conduction pathways (through its thermally conductive material) that transfer heat from the sealed component area to the open ventilation area, enabling heat dissipation without compromising the seal of the component space.
2Strength
If the camera body is designed with heavy-duty materials and thick walls to ensure mechanical stability, then structural strength is improved, but accessibility to internal components for servicing deteriorates
Solution Approach 1:
The camera body is segmented into a permanent main body (providing structural strength) and a removable side cover (providing access). The carrier structure forms the rigid framework while the side cover can be detached to expose electronic components, allowing servicing without compromising the overall structural integrity of the camera body.
Solution Approach 2:
The side cover transitions from a fixed state (during normal operation providing protection) to a movable/removable state (during servicing providing access). This dynamic design allows the camera body to adapt between its protective and accessible functions, maintaining structural strength while enabling easy repair when needed.
3Volume of moving object
If the camera body is designed with a compact layout to reduce size, then volume is reduced, but heat dissipation efficiency deteriorates
Solution Approach 1:
The ventilation space is designed to extend along the longitudinal axis of the camera body, utilizing the length dimension for heat dissipation. The cooling passage runs longitudinally through the carrier structure, allowing heat to be dissipated along the length of the camera rather than requiring increased cross-sectional area, thus maintaining compact volume while improving heat dissipation efficiency.
Solution Approach 2:
The carrier structure incorporates thermally conductive materials specifically in regions where heat transfer is needed (such as the cooling passage walls adjacent to electronic components), while other parts of the camera body can use different materials optimized for their specific functions. This localized thermal conductivity enhancement improves heat dissipation without requiring a complete redesign of the entire camera body structure.

AI summary
An electronic video camera has a camera body which comprises an inner carrier structure and at least one outer cover element which is arranged at the carrier structure and which bounds an interior space of the camera body. In this respect, the camera structure forms a central cooling passage which divides the interior space of the camera body into a ventilation space within the cooling passage and into at least one component space outside the cooling passage. The ventilation space is open toward the environment of the video camera. The component space is sealingly closed with respect to the ventilation space and the environment of the video camera. The video camera has electronic components which are received in the component space and are thermally conductively coupled to the ventilation space via at least one side wall of the cooling passage. The cover element furthermore forms a side cover which is releasable to expose the electronic components arranged in the component space for servicing purposes.
