Hand-Mounted Phone Holder With Elastic Finger Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cell phones are often dropped while being used due to difficulty in holding them in desirable positions, leading to accidental key manipulation errors and potential damage.
Innovation Solution
A system using elastic straps to securely attach a cell phone to the inside of a user's hand, specifically capturing the middle and ring fingers, allowing for rotational positioning and easy removal for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cell phone is held in one hand with fingers straddling the front, then the phone can be manipulated with the thumb, but the phone is difficult to hold in desirable positions and may be dropped
Solution Approach 1:
An elastic mounting system with straps serves as an intermediary between the user's hand and the cell phone. The mounting plate with loops captures the middle and ring fingers, while the elastic bands provide flexible attachment, allowing the phone to be securely held without direct manual gripping that leads to drops
Solution Approach 2:
The mounting system divides the attachment function into separate components: a mounting plate with loops for finger capture, elastic bands for flexible attachment, and a mounting mechanism for securing the phone. This segmentation allows each component to perform its specific function optimally while working together to solve the stability problem
2Adaptability or versatility
If elastic straps are used to attach the cell phone to the hand, then the phone stays snug on hands of different sizes, but the mounting system becomes more complex
Solution Approach 1:
The elastic bands change their physical parameters (length, tension) dynamically to adapt to different hand sizes and finger configurations. The loops can expand or contract to accommodate various finger thicknesses, allowing the same mounting system to fit different users without requiring multiple sizes or complex adjustments
Solution Approach 2:
The mounting system is designed with universal applicability through the elastic loops that can accommodate different hand sizes and the flexible mounting plate that adapts to various phone models. This multi-functionality allows a single design to serve multiple purposes and users, reducing the need for complex size-specific variants
3Reliability
If the cell phone is securely attached to the hand, then drops are reduced, but the phone cannot be easily removed for maintenance
Solution Approach 1:
The mounting system incorporates dynamic elements that allow it to transition between secure attachment and easy removal states. The elastic bands provide continuous tension for secure holding during use, but the entire mounting plate can be dynamically detached from the phone by releasing the elastic tension, enabling quick removal for maintenance when needed
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 system provides a secure and ergonomic hold for cell phones, reducing the likelihood of drops and errors during use while allowing for easy access for maintenance.
Implementation Method 1
Elastic straps are used because there are many different hand sizes and fingers but no matter of the different hand and finger sizes, the cell phone will stay snug on the hand
Implementation Method 2
it is desirable that the instrument will remain rotational relative to the mounting plate of the straps and thereby relative to the hand that is holding the cell phone

AI summary
A system for attaching an electronic instrument to the inside of a hand. The system includes a fixed plate removably attached to an electronic instrument. The system further consists of a fixed plate attached to the cell phone and a rotational plate attached to the fixed plate. The rotational plate has threaded there through an elastic band having loops, each of which will connect to a middle finger and a ring finger, respectively, designed to hold the hand of a user snugly on the electronic instrument. The fixed plate may also be attached to a case of a cell phone.
