Multi-Camera Frame Fan Structure for Individual Fan Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance cameras require disassembly of multiple frame fans to replace a single fan, which is inconvenient due to their rotatable coupling to the frame bottom.
Innovation Solution
A multi-camera assembly with individually detachable frame fans supported by a connection structure that includes a ring member, first fastening members, and extension members, allowing selective attachment and detachment without interference during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frame fans are rotatably coupled to the frame bottom for panning movement, then the camera modules can perform panning rotation, but removing a single frame fan requires disassembly of multiple frame fans
Solution Approach 1:
The coupling structure is segmented into separate components: a coupling portion on the frame fan and a connection portion on the frame bottom. This segmentation allows the frame fan to be independently attached and detached without requiring disassembly of other frame fans, resolving the contradiction between ease of replacement and structural complexity.
Solution Approach 2:
The connection structure is extracted as a separate functional element (connection portion with ring member and fastening members) that can be independently configured. This extraction enables the frame fan to be selectively removed by detaching only its specific connection portion, eliminating the need to disassemble multiple fans while maintaining the rotational coupling function.
2Adaptability or versatility
If multiple frame fans are arranged around the frame bottom, then multiple camera modules can be supported, but assembly interference occurs during fan attachment
Solution Approach 1:
Each connection portion is configured with local quality features: ring members positioned at specific locations and fastening members arranged at different angles. This local differentiation allows multiple frame fans to be attached simultaneously without interference, as each fan's connection portion is uniquely positioned and oriented, enabling versatile camera module support while maintaining ease of assembly.
Solution Approach 2:
The connection portions are arranged in different spatial dimensions: ring members are positioned at different angular positions around the frame bottom, and fastening members are oriented at different angles. This dimensional arrangement allows multiple frame fans to coexist without assembly interference, supporting multiple camera modules while simplifying the manufacturing process.
3Ease of operation
If frame fans are rotatably coupled to enable panning, then camera modules can rotate, but impact is transmitted to camera modules during rotation
Solution Approach 1:
The connection portion acts as an intermediary element between the frame bottom and the frame fan. The ring member and fastening members in this intermediary structure reduce impact transmission during panning rotation, allowing the camera modules to rotate smoothly while protecting them from harmful forces generated during movement.
