Solution Overview
Problem
Existing modular electronic assemblies in devices like video surveillance systems installed at heights face difficulties in maintenance due to restricted operator movement and sensitivity to climatic conditions, making module replacement challenging and prone to accidents.
Innovation Solution
A modular electronic assembly with a pivoting mechanism and clipping hook system that allows single-handed operation, combined with magnetic retention and stop mechanisms to secure modules in place, facilitating easy installation and removal without tools, and reducing the risk of accidental falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screw fixing means are used to secure modules on the support, then the module is firmly fixed, but the removal and installation process becomes complex and requires two hands and special tools
Solution Approach 1:
The fixing mechanism is segmented into two independent functions: a clipping mechanism for easy attachment/detachment and a magnetic retention mechanism for secure holding. This segmentation allows each mechanism to be optimized for its specific function, making module removal and installation simple while maintaining firm fixation.
Solution Approach 2:
A magnetic retention mechanism acts as an intermediary between the module and the support structure. The magnet provides automatic retention without requiring direct mechanical connection, enabling tool-free removal while ensuring secure fixing during operation.
2Adaptability or versatility
If modules are mounted high up on supports like CCTV cameras on pylons, then the system can monitor wide areas, but access for maintenance becomes dangerous and difficult
Solution Approach 1:
The magnetic retention mechanism enables self-service maintenance operations. The magnet automatically retains the module during operation, and the same magnetic force assists in removing the module during maintenance, eliminating the need for complex manual handling procedures even at heights.
Solution Approach 2:
The clipping mechanism changes the interaction parameter between the module and support from requiring significant mechanical force (screw fixing) to requiring minimal force (magnetic retention), making maintenance operations feasible at difficult locations without specialized equipment.
3Reliability
If manual screw fixing is used for modules, then the connection is secure, but the operation time for replacement increases significantly
Solution Approach 1:
The magnetic retention mechanism is pre-configured to automatically engage when the module is inserted into the support. This preliminary action eliminates the need for time-consuming screw fastening operations during installation and removal, while maintaining secure connection throughout operation.
Solution Approach 2:
The traditional mechanical screw-fixing system is replaced with a magnetic retention system. This substitution maintains connection security through magnetic force while dramatically reducing the time required for module replacement, as no manual fastening or unfastening operations are needed.
4Ease of repair
If operators work in exposed conditions on ladders or mobile platforms, then module replacement can be performed, but safety risks increase due to climatic conditions
Solution Approach 1:
The magnetic retention mechanism enables maintenance operations to be performed with minimal manual handling required. The magnet automatically secures the module, reducing the operator's exposure time in dangerous conditions and eliminating the need for complex manual manipulation that increases safety risks.
Solution Approach 2:
The magnetic retention mechanism provides beforehand cushioning by automatically securing the module before any manual handling is required. This prevents accidental drops or misplacement during the maintenance process, reducing safety risks associated with working in exposed conditions.
