Wrist-Mounted Phone Case With Snap-Strap Quick Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing phone accessories require one hand to hold the phone or are bulky and inconvenient for quick detachment from protective cases, lacking a versatile and ergonomic solution for hands-free use and angle adjustment.
Innovation Solution
A wrist-mounted phone case with a snap strap and button mechanism allows quick detachment and reattachment, enabling hands-free operation and adjustable horizontal or vertical positioning on the wrist or a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive based accessories are used to attach phone, then phone can be held more easily, but one hand is still occupied and phone cannot be detached quickly
Solution Approach 1:
The attachment system is divided into separate components: a wrist strap with stud and a phone case with socket. This segmentation allows the phone to be quickly detached by simply releasing the button mechanism, eliminating the time-consuming process of removing adhesive accessories while maintaining easy holding capability through the wrist strap.
Solution Approach 2:
The button mechanism provides dynamic attachment and detachment capability. The button can be quickly pressed to release the phone from the wrist strap, enabling rapid transitions between held and detached states. This dynamic system resolves the contradiction by making detachment fast while maintaining secure attachment during use.
2Adaptability or versatility
If strap based phone holders are used, then hands-free use is enabled, but they are bulky and inconvenient for quick detachment
Solution Approach 1:
The wrist strap is constructed from a thin, flexible material that can conform to the wrist shape, providing a compact and comfortable fit. This flexible design enables hands-free phone carrying without the bulkiness of traditional rigid strap holders, while the integrated button mechanism ensures quick detachment capability.
3Loss of time
If phone case with button mechanism is used, then quick detachment is enabled, but attachment security must be maintained
Solution Approach 1:
The button mechanism features a stud with a rounded head that fits into a socket with a corresponding cavity. The curved surfaces of the button components allow for easy pressing and releasing actions, enabling quick detachment and reattachment. Despite the simplicity of the button press action, the interlocking geometry of the stud and socket ensures secure attachment when engaged.
Applied Scientific Principles

AI summary
The phone mounting device enables hands-free use of a mobile phone by securely holding it on a user's wrist. The device includes a phone case with an integrated socket mechanism that connects to a stud on a wrist strap. Made of a metal snap strap covered with durable material like silicon, the wrist strap allows quick detachment and reattachment of the phone case and mobile phone together, without needing to remove the phone from its case. The adjustable strap ensures a comfortable fit and enables the phone to rest horizontally or vertically on a surface without additional accessories. This device offers a seamless, secure connection and addresses common challenges in carrying and using mobile phones, providing easy access and usability without requiring the user to hold the phone.
