Device Clip With Spring Locking Rod For Camera Bag Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing a camera bag to a backpack, such as using Velcro tape, suffer from reduced binding force over time, leading to connection instability and the need for frequent replacements, compromising convenience and mobility.
Innovation Solution
A device clip comprising a first jaw member with a coupling and locking part, and a second jaw member with a pivot connection, locking unit, and spring mechanism, allowing for secure and stable attachment of the camera bag to the backpack by engaging a rod member into a retaining groove, utilizing elastic potential energy for a firm lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Velcro tape is used to secure camera bag to backpack, then ease of operation is improved, but reliability deteriorates over time due to reduced binding force
Solution Approach 1:
The Velcro tape is divided into two separate components: a loop tape portion attached to the backpack and a hook tape portion attached to the camera bag. This segmentation allows independent replacement of worn components and maintains functional effectiveness over time.
Solution Approach 2:
The connection system transitions from a static, permanently degrading Velcro tape to a dynamic system where the binding force can be maintained through periodic reconfiguration - separating and reattaching the loop and hook portions to restore optimal binding capability.
2Ease of operation
If Velcro tape is used for securement, then ease of operation is improved, but duration of action deteriorates due to need for frequent replacement
Solution Approach 1:
The loop tape portion is designed to be permanently attached to the backpack (discarding it from replacement), while the hook tape portion can be detached, recovered, and reattached to the camera bag. This allows the permanent component to accumulate durability while the removable component can be replaced if needed.
3Weight of moving object
If camera is carried in backpack, then weight distribution is improved, but accessibility deteriorates requiring opening backpack
Solution Approach 1:
The camera bag is nested within or attached to the backpack structure, allowing the camera to be carried within the backpack's weight-bearing system while remaining externally accessible through the bag's opening, combining the benefits of internal weight distribution with external accessibility.

AI summary
A device clip includes a first jaw member, and a second jaw member having fixed end pivotally connected to one end of the first jaw member and a free end provided with a rod member that is movable along the major axis of the second jaw member by an external force and can return to its former position when the external force disappears. Thus, the other end of the first jaw member is detachably lockable to the rod member at the free end of the second jaw member for enabling the device clip to conveniently and steadily link two objects together, for example, to link a camera bag to a backpack.
