Modular Camera Hanger Structure for Safe Magnetic Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera apparatuses face challenges in easy detachment and replacement, leading to a risk of damage during removal due to strong magnetic forces and complex structures, which complicate the decoupling process and increase the likelihood of the camera being dropped.
Innovation Solution
A camera apparatus design featuring a hanger with a through hole and protrusion on the main body, allowing for easy detachment from a plate using magnetic or Velcro attachments, which reduces the risk of the camera being dropped by providing a secure and user-friendly decoupling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnet is used to couple the modular camera to the housing, then the coupling strength is improved, but the ease of decoupling deteriorates
Solution Approach 1:
The coupling system is divided into two independent parts: a magnet for strong coupling and a hanger with hole for easy decoupling. The hanger is connected to the camera body while the hole allows finger insertion to pull the camera away from the housing, separating the coupling function from the decoupling function.
Solution Approach 2:
The hanger acts as an intermediary component between the camera body and the housing. It provides a mechanical interface (the hole) that mediates the decoupling action, allowing the user to easily separate the camera from the housing without directly overcoming the magnetic force.
2Reliability
If additional safety wires or connection structures are added to prevent camera dropping, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The decoupling function and safety function are merged into a single component - the hanger. The same hanger that enables easy decoupling also serves as a safety feature by allowing the user to maintain control of the camera during removal, eliminating the need for separate safety wires or connection structures.
Solution Approach 2:
The hanger structure provides its own safety function without requiring additional components. The hole in the hanger allows the user's finger to act as a safety mechanism, enabling the user to control the camera's movement during decoupling and prevent dropping without any extra safety devices.
3Stability of the object's composition
If the hanger is positioned at the center of the main body, then the coupling stability is improved, but the ease of detachment deteriorates
Solution Approach 1:
The hanger is positioned asymmetrically at a corner or side of the camera body rather than at the center. This asymmetric positioning creates a lever arm that provides mechanical advantage for detachment while the attachment point remains stable. The offset position allows the user to apply force more effectively for removal.
Solution Approach 2:
The hanger extends outward from the camera body in a different spatial dimension, creating a lever arm that provides mechanical advantage. This dimensional extension allows the user to apply detachment force at a greater distance from the coupling point, reducing the effort required for removal while maintaining stable coupling during operation.
