Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face discomfort and potential injury from holding handheld electronic devices, such as smartphones, for extended periods, leading to arm and shoulder pain, and neck strain due to improper viewing angles and postures, which limits mobility.
Innovation Solution
A waist-worn holder with a hoop body and adjustable semi-rigid cord system allowing 360-degree positioning of the device, featuring quick-release locks and a sliding runner mechanism for secure, hands-free operation and adjustable alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the smartphone is held in the hand for extended periods, then the device can be used for various tasks, but arm and shoulder pain occurs
Solution Approach 1:
The holder divides the support function into multiple components: a waist-worn hoop body and a separate adjustable bracket connected by a semi-rigid cord. This segmentation allows the device to be supported away from the hands while maintaining usability, eliminating arm and shoulder strain.
Solution Approach 2:
The semi-rigid cord acts as an intermediary element connecting the waist-mounted hoop body to the device bracket. It transmits the support function from the waist to the device while allowing positional adjustment, enabling hands-free operation without direct hand holding.
2Ease of operation
If the smartphone is placed on a table or stand, then hands-free operation is possible, but proper viewing angles cannot be achieved and neck injury may occur
Solution Approach 1:
The bracket is designed with dynamic adjustment capabilities through the semi-rigid cord and sliding mechanism, allowing the user to position the smartphone at various angles and orientations. This dynamic positioning enables proper viewing angles tailored to each user, preventing neck injury while maintaining hands-free operation.
Solution Approach 2:
The holder system allows changing of positional parameters (height, angle, orientation) of the smartphone through the adjustable bracket and cord mechanism. By varying these parameters, users can achieve optimal viewing angles for different tasks, eliminating the need for fixed-position stands that cause neck strain.
3Adaptability or versatility
If the holder structure is made complex to allow 360-degree adjustment, then positioning flexibility is improved, but device complexity increases
Solution Approach 1:
The semi-rigid cord provides flexible positioning capability while maintaining a simple structure. Its semi-rigid nature allows it to hold position when set while remaining flexible enough to enable 360-degree adjustment, achieving high adaptability without complex mechanical components.
Solution Approach 2:
The holder utilizes the third dimension (vertical space from waist to device level) to provide positioning flexibility. By mounting the device at waist level and using the cord length and bracket orientation for adjustment, the system achieves 360-degree positioning capability without requiring complex multi-axis mechanisms.

AI summary
A holder for handheld electronic devices, such as a smartphone. The holder includes a hoop body configured to be worn around a waist of a person. The hoop body having a proximal end and a distal end, wherein the proximal end and the distal end having a quick release lock to couple to the proximal end to the distal end. The hoop body having a tunnel configured around its outer periphery. A runner connected to a bracket through a semi-rigid extension. The runner, slidably received in the tunnel, can revolve along its length. The bracket can mount the handheld electronic device.
