Shoulder Strap Elastic Support for Chest-Mounted Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strap devices for carrying electronic devices across the shoulder against the chest often result in the device slipping or being tossed under the arm, and require frequent adjustments to position the device for use, while also being vulnerable to theft or falling.
Innovation Solution
A strap device with a band support that includes elastic return means to securely fix the electronic device against the chest, preventing it from falling or being stolen, and allows for adjustable positioning and remote control functionality through sensors and control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is suspended from the shoulder strap via an attachment system, then the device can be carried against the user's chest, but the device will bounce or slip under the user's arm
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the support band to move between a retracted position (when not in use) and an extended position (when needed). This dynamic capability enables the device to adapt to different user needs: secured firmly during normal wear to prevent bouncing, and easily accessible when the user needs to adjust or use the device
Solution Approach 2:
The elastic retraction means continuously exert a retracting force on the support band, keeping it in a predetermined retracted position before use. This preliminary action ensures the device is always secured against bouncing during normal wear, while allowing quick deployment when needed by simply overcoming the elastic force
2Ease of operation
If the support band is made detachable for easy access, then the user can adjust the device for use, but the device becomes vulnerable to falling or theft
Solution Approach 1:
The elastic retraction means continuously applies a securing force to the support band, counteracting any tendency for the band to detach or the device to fall. This preliminary anti-action maintains constant security pressure on the connection, making accidental detachment unlikely while still allowing intentional release when needed
Solution Approach 2:
The support band acts as an intermediary element between the shoulder strap and the electronic device. It provides a controlled interface that allows easy access when detached intentionally, while the elastic retraction means ensures it remains securely connected during normal use, mediating between security and accessibility requirements
3Ease of operation
If the support band is extended for device accessibility, then the user can reach the device for operations, but the device may be torn from or fall off the strap
Solution Approach 1:
The support band transitions between retracted and extended states dynamically. During normal wear, it remains retracted maintaining strong connection. When the user needs access, the band extends to allow device manipulation. The elastic retraction means ensures that even when extended, the band maintains sufficient tension to prevent accidental detachment
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 strap device securely holds the electronic device against the chest, preventing slipping and theft, while allowing for easy adjustment and remote control of device functions, enhancing user interaction and safety.
Implementation Method 1
said return means are designed to elastically return the support from the position of use to the rest position
Implementation Method 2
the connecting means operate by magnetic attraction

AI summary
The invention relates to a device (1) with a belt (4) for carrying an electronic apparatus (2) over the shoulder against the chest (3) of a user. The device comprises, in particular, a support (5) with a strap for the electronic apparatus. The belt of the device has two ends (4') between which the strap support is attached along its length in order to form the shoulder strap. The strap support has a first face (5') orientated on the chest side when the belt is worn over the shoulder and a second face (5''), opposite the first face, said second face comprising attachment means designed to fasten the second face flat against the electronic device.
