Modular Extension Assembly for Sealed Electronic Circuit Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cameras and outdoor base stations face limitations in functional flexibility due to pre-installation of required circuits, leading to incomplete or redundant functions, and issues with air tightness and heat dissipation.
Innovation Solution
An electronic device with a primary assembly and extension assembly, allowing for detachable and flexible installation of extension circuits such as communication modules and processors, using a combination of slots, tongues, and fasteners for quick connection and disassembly, along with a shielding cover assembly for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional circuits are installed in a camera before delivery, then the camera structure is complete and stable, but the functional flexibility is reduced and cannot be adjusted after delivery
Solution Approach 1:
The camera system is divided into a main body and separate functional extension assemblies. Each extension assembly contains specific functional circuits (communication, processing, etc.) that can be independently installed or removed. This segmentation allows functional flexibility while maintaining a simple base structure.
Solution Approach 2:
The extension assembly introduces a dynamic installation structure with slots and tongues that enable post-delivery configuration changes. Users can add or remove functional circuits based on actual needs, transforming the static camera into a dynamically configurable system without increasing overall installation complexity.
2Adaptability or versatility
If functional circuits are added to meet different user requirements, then the functionality is enhanced, but the installation cannot be performed after delivery
Solution Approach 1:
The extension assembly is pre-configured with specific functional circuits during manufacturing, but the actual installation into the camera body is deferred until needed. This preliminary preparation of functional modules enables timely installation after delivery, allowing users to customize functionality based on actual deployment requirements rather than forcing all configurations to be decided beforehand.
3Adaptability or versatility
If the primary device assembly is disassembled for extension circuit installation, then the functional flexibility is improved, but the air tightness is affected
Solution Approach 1:
The functional extension assembly is extracted as a separate unit that interfaces with the camera body through a dedicated opening. This extraction approach allows the extension to be installed without disassembling the main air-tight structure of the camera body. The opening is specifically designed to maintain sealing while enabling extension installation.
4Productivity
If a detachable connection structure is used for quick installation, then the installation efficiency is improved, but the connection stability may be reduced
Solution Approach 1:
The detachable connection structure merges multiple functions into a single integrated mechanism: the tongue inserts into the slot for mechanical connection, while simultaneously electrical contacts establish signal connections. This merging achieves quick installation through a single insertion action while maintaining stable both mechanical and electrical connections through the combined design.
