Retractable Finger-Hole Bracket for Secure Electronic Device Grip

Solution Overview

Problem

Conventional electronic devices lack a specifically designed holding portion for a firm grip, increasing the risk of dropping or slippage when used with one hand, and existing solutions like external straps or hand supports are cumbersome and difficult to conceal.

Innovation Solution

A holding support system comprising a case with a bracket compartment and an extendable bracket featuring finger holes, allowing for secure grip when extended and space-saving retraction when not in use, which can be integrated into the device's housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an external strap or hand support is added to the housing, then the grip firmness is improved, but the device complexity and space occupation increase

Engineering Contradiction:

Improvegrip firmnessVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bracket is nested within a recess formed in the housing. When not in use, the bracket is concealed inside the housing, maintaining a sleek appearance. When needed, the bracket can be extended outward to provide grip support, thus resolving the contradiction between grip firmness and device complexity by hiding the structural element when not required.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The bracket is designed to be movable rather than fixed, allowing it to extend outward when grip support is needed and retract into the recess when not in use. This dynamic configuration enables the device to adapt between two states: one optimized for grip firmness and another for sleek appearance and space efficiency, thereby resolving the technical contradiction.

AI summary

A holding support for electronic device is disclosed, which includes a case and a bracket. A bracket compartment is formed on the case and defined by an opening formed on the outer surface of the case. The bracket has a body and at least one finger hole formed thereon for sliding a finger through. The bracket can be retracted in or extended from the bracket compartment by being arranged at a retracted position or extended position, respectively. Therefore, the user can firmly secure the electronic device and prevent from dropping it accidentally.
