Suspension Arrangement for Monitoring Device Secure Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension arrangements for monitoring devices, such as surveillance cameras, face issues with secure engagement and risk of unintentional disengagement, particularly due to the design of leaf spring-based hooks that can break under weight and are difficult to unhook.
Innovation Solution
A suspension arrangement featuring a hook member, a blocking member, and a resilient member that transitions between open and closed states based on the weight of the monitoring device, ensuring secure engagement and preventing disengagement through the use of a slot and blocking member configuration, allowing the resilient member to absorb impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a leaf spring is used to create a gap for receiving the safety wire, then the hook member can be easily opened for engagement, but the gap is small making unhooking difficult and the leaf spring may break under load
Solution Approach 1:
The hook member is divided into two separate components: the hook member itself and the resilient member (leaf spring). This segmentation allows the hook member to be designed for easy opening while the resilient member provides the necessary locking force, eliminating the structural weakness of integrating both functions into a single leaf spring component.
Solution Approach 2:
The blocking member is extracted as a separate component from the hook member assembly. This blocking member actively prevents disengagement by blocking the slot, separating the engagement function (hook member) from the retention function (blocking member), thereby solving both the ease of opening and the reliability of retention.
2Ease of operation
If the hook member is designed to be easily opened for receiving the wire, then engagement is simplified, but unintentional disengagement becomes more likely
Solution Approach 1:
The blocking member is positioned to proactively prevent disengagement before it can occur. By placing the blocking member to block the slot in the closed state, the design anticipates and counteracts potential unintentional disengagement, allowing easy engagement while maintaining security.
Solution Approach 2:
The system transitions between two dynamic states: closed state where the blocking member actively prevents disengagement, and open state where the hook member can receive the wire. This dynamic switching allows the system to provide both easy engagement and secure retention at different operational phases.
3Reliability
If the resilient member biases the hook member toward the closed state, then disengagement is prevented, but impact forces from the monitoring device weight are not adequately absorbed
Solution Approach 1:
The resilient member (leaf spring) is positioned to absorb impact forces before they can damage the hook member or mounting structure. By placing the resilient member between the hook member and the mounting bracket, it provides beforehand cushioning that protects the system from the harmful impact forces generated when the monitoring device is suspended.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy engagement and secure suspension of monitoring devices without manual interaction, preventing unintentional disengagement and providing a damping effect to protect against impact forces, thus ensuring reliable and safe operation during installation and use.
Implementation Method 1
The resilient member is arranged to bias the suspension arrangement toward the closed state
Implementation Method 2
The suspension arrangement is configured such that when the monitoring device is suspended by the suspension arrangement, the hook member is adapted to carry the weight of the monitoring device and thereby to transfer the load to the resilient member
