Detachable Bracket Guiding Slot Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device casings with detachable brackets are inconvenient for rotation, detachment, and reinstallation, limiting maintenance and replacement of electronic components due to restricted rotation angles and complex alignment requirements.
Innovation Solution
A device casing design featuring guiding slots and sliding posts that allow the detachable bracket to rotate and detach easily, with a structural constraint enabling stable rotation and convenient installation by sliding and rotating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable and detachable bracket is designed with holes and pull pins forming a hinge structure, then the bracket can be detached from the device casing, but the installation becomes inconvenient due to alignment requirements and the rotation angle is restricted
Solution Approach 1:
The bracket is divided into a fixed portion attached to the device casing and a movable portion that can rotate and detach independently. This segmentation allows the bracket to provide both rotational functionality and detachability without requiring complex alignment between holes and pins, as the fixed and movable portions can be connected through a simpler hinge mechanism.
Solution Approach 2:
A hinge structure serves as an intermediary mechanism between the fixed and movable portions of the bracket. This hinge allows smooth rotation and controlled detachment without requiring precise alignment of multiple components, thereby improving ease of operation while maintaining adaptability.
2Adaptability or versatility
If the bracket is designed to rotate through a hole and shaft fit with pull pins, then the bracket can be detached, but the allowable rotation angle is not large and it is uneasy to make the bracket immovable
Solution Approach 1:
The bracket incorporates a dynamic hinge mechanism that allows rotation during operation but can be easily locked into an immovable position when needed. This dynamic design enables the bracket to transition between rotatable and fixed states, providing both adaptability and stability without compromising either characteristic.
3Reliability
If electronic components are fixedly disposed individually by screws, then the components are securely mounted, but maintenance and replacement require opening the device casing and loosening screws which is inconvenient
Solution Approach 1:
Electronic components are grouped and mounted on the movable portion of the bracket as a unit rather than being individually fixed to the device casing. This segmentation allows all components on the bracket to be accessed, maintained, or replaced together by simply detaching or rotating the bracket, eliminating the need to open the entire device casing or loosen individual screws.
Solution Approach 2:
The movable portion of the bracket with attached electronic components can be extracted from the device casing as a complete assembly. This extraction enables convenient maintenance and replacement of components without affecting the overall device structure or requiring disassembly of the casing, while the components remain securely mounted on the bracket during normal operation.

AI summary
A device casing includes a casing body and a detachable bracket. The casing body has first and second supporting frames opposite to each other, and first and second guiding slots formed on the first supporting frame. The first guiding slot has a first open end and a first closed end. The second guiding slot has a second open end and a second closed end. The detachable bracket is detachably disposed between the first and second supporting frames and has first and second sliding posts. The first sliding post is rotatably disposed at the first closed end. The second sliding post is slidably disposed at the second closed end. By the structural constraint between the first and second guiding slots and the first and second sliding posts respectively, the detachable bracket can stably rotate relative to the casing body and can be installed onto the casing body easily.
