Camera Strap Fixing Device for Neck and Hand Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera strap systems require cumbersome and time-consuming detachment and reattachment processes when switching between neck and hand straps, causing user inconvenience and discomfort due to the weight distribution on the neck and back.
Innovation Solution
A fixing device with a main body and threaded post that can be removably attached to a camera strap, allowing it to be divided into adjustable sections, enabling quick conversion between neck and hand/wrist strap modes by screwing into the camera's threaded hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a neck strap is used to hold the camera, then the camera can hang conveniently in front of the user's chest, but the weight of the camera causes pain in the neck and back after long use
Solution Approach 1:
The patent implements a dynamic strap system where the fixing device can be quickly repositioned along the strap length. The strap transitions between different configuration states (neck strap mode with camera hanging at chest level, hand strap mode with camera held closer to body center) to adapt to varying comfort needs during different shooting scenarios
2Reliability
If a hand strap is used to hold the camera, then the camera can be held tight to one hand ready for shooting, but the user only has one hand free to handle other tasks
Solution Approach 1:
The system enables dynamic switching between hand strap configuration (camera held securely in one hand) and neck strap configuration (camera hanging freely at chest). The quick-adjust mechanism allows users to transition between these states without removing the strap, maintaining camera readiness while periodically freeing hands for other tasks
3Adaptability or versatility
If users buy both neck strap and hand strap to switch between modes, then both carrying comfort and camera readiness can be achieved, but changing strap involves cumbersome and time-consuming detaching and attaching work
Solution Approach 1:
The patent creates a universal strap system where a single strap can function in multiple modes (neck strap and hand strap) through the repositionable fixing device. This eliminates the need for separate neck and hand straps, consolidating multiple functions into one accessory while enabling quick mode switching
Solution Approach 2:
The strap is effectively segmented into adjustable sections by the repositionable fixing device. Users can divide the strap at different points along its length to create the desired configuration, whether for neck or hand carrying, without needing to physically separate or replace the entire strap
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
Enables easy and convenient switching between neck and hand/wrist strap modes, reducing the time and effort required for strap changes and alleviating neck and back discomfort by allowing adjustable weight distribution.
Implementation Method 1
a threaded post connected to the main body. The main body is configured to be removably disposed on the strap, and the threaded post is configured to be screwed into the threaded hole of the camera

AI summary
A fixing device adapted for a camera having a threaded hole and for a strap with two opposite ends fixed to the camera is provided. The fixing device includes a main body and a threaded post connected to the main body. The main body is configured to be removably disposed on the strap, and the threaded post is configured to be screwed into the threaded hole of the camera. When the main body is disposed on the strap and the threaded post is screwed into the threaded hole, the fixing device divides the strap into a first section and a second section that respectively form a first area and a second area with the camera.
