Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating devices fail to precisely control the angles of rotation, making it difficult to maintain a normal working angle when removing screws from mobile phone display panels, which requires fixing the phone at different angles.
Innovation Solution
A rotating device comprising a base, an angle defining disk, a rotating mechanism, and a positioning mechanism that allows for precise control of rotation angles by using a disk with evenly or non-uniformly arranged V-shaped locating slots, a shaft, and an elastic rotating handle to position and rotate the device at predetermined angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screwdriver is used to remove screws from a mobile phone display panel, then the screw removal operation can be performed, but the mobile phone must be fixed at different angles which increases operation complexity and reduces efficiency
Solution Approach 1:
The device segments the rotation control function into discrete angular positions using locating slots on the rotating disk. Each slot corresponds to a predetermined angle, allowing the user to select and fix the phone at specific orientations without manual angle adjustment, thus simplifying the operation while removing screws.
Solution Approach 2:
The rotating disk with locating slots acts as an intermediary mechanism between the user's rotation action and the phone's orientation. Instead of directly fixing the phone at different angles, the user rotates the disk to selected slots, which automatically positions the phone at the correct angle through the connection mechanism, reducing operational complexity.
2Adaptability or versatility
If existing rotating devices are used, then rotation function is provided, but the angles of rotation are not precisely controlled which reduces manufacturing precision
Solution Approach 1:
The locating slots on the rotating disk are pre-positioned at specific angular intervals corresponding to predetermined rotation angles. This preliminary arrangement of slots allows the rotating mechanism to automatically achieve precise angular positioning without requiring complex control systems, thereby improving rotation angle precision while maintaining adaptability.
Solution Approach 2:
The device changes the parameter of rotation angle control from continuous adjustment to discrete predetermined values. By using locating slots at specific angular positions, the system transforms the rotation control into a parameter-based selection mechanism, ensuring precise angular positioning for different screw removal operations.
3Ease of operation
If manual angle adjustment is performed without precise control, then rotation can be achieved, but the stability and reliability of the rotation position is reduced
Solution Approach 1:
The locating slots provide tactile and visual feedback when the rotating disk reaches a predetermined angle. The user can feel the slot engagement and see the position indicator align with the slot, confirming the exact angular position. This feedback mechanism ensures reliable and repeatable positioning while maintaining ease of operation during screw removal.
Solution Approach 2:
The rotating mechanism with locating slots is designed to self-position at predetermined angles without requiring external measurement or adjustment tools. The slots automatically guide the rotation to correct positions, and the connection mechanism between the disk and phone ensures stable positioning, making the system self-sufficient for precise angle control.

AI summary
A rotating device configured to rotate and position a product at multiple precision angles includes a base and an angle defining disk. The angle defining disk defines a circular through hole. A rotating mechanism is received in the through hole and a positioning mechanism is connected to the rotating mechanism. The periphery of an inner wall of the through hole includes a plurality of locating slots. The rotating mechanism is capable of rotating in the through hole by an external force and driving the positioning mechanism to rotate relative to the angle defining disk. The rotation causes the rotating mechanism to move and take a precise position from one locating slot to another locating slot.
