Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen is allowed to rotate freely during disassembly and assembly, then the assembly and disassembly process becomes more flexible, but it causes damage to the bottom base or desk and makes reassembly difficult
Solution Approach 1:
The patent applies preliminary action by positioning the screen at a predetermined height on the support frame before disassembly begins. The positioning groove and positioning pin mechanism ensure the screen is pre-positioned in a safe horizontal state, preventing rotation damage before the disassembly process starts. This pre-positioning resolves the contradiction by establishing safety conditions before operational flexibility is needed.
Solution Approach 2:
The positioning groove and positioning pin act as intermediary structures between the screen and support frame. These intermediaries constrain the screen's movement during disassembly and assembly, allowing flexible operation while preventing harmful rotation. The intermediary mechanism enables the screen to be moved vertically for easy assembly/disassembly while maintaining horizontal orientation to prevent damage.
2Ease of operation
If the pushed portion of the first buckling ring is accessible during screen rotation, then the buckling ring can be easily actuated, but the screen may be accidentally separated from the coupling frame and fall
Solution Approach 1:
The stopping ring serves as an intermediary safety mechanism between the user's hand and the pushed portion of the buckling ring. It allows intentional actuation of the buckling ring while blocking accidental touches during screen rotation. The stopping ring transmits deliberate pressing forces to the buckling ring while preventing unintended contact, resolving the contradiction between ease of operation and safety.
Solution Approach 2:
The stopping ring applies preliminary anti-action by physically blocking access to the pushed portion of the buckling ring during screen rotation. This pre-emptive barrier prevents accidental separation before it can occur, while still allowing intentional actuation when needed. The stopping ring's positioning creates a controlled access mechanism that resolves the safety-operability contradiction.
3Adaptability or versatility
If the screen position is not restricted to specific heights, then the screen can be positioned flexibly, but the screen cannot be raised in height when vertical and cannot be turned vertical when raised
Solution Approach 1:
The patent applies dynamics by creating a conditional positioning system where the screen's movement capabilities change based on its position. When the screen is at a predetermined height, it can be rotated horizontally or vertically. When rotated to vertical position, the positioning groove and pin mechanism dynamically restrict further height adjustment. This dynamic behavior provides adaptability for different operational states while maintaining safety interlocking.
Solution Approach 2:
The positioning mechanism segments the screen's movement into distinct phases: vertical adjustment phase (when horizontal) and rotation phase (at predetermined height). The positioning groove and pin create discrete positioning states that separate height adjustment and rotation operations. This segmentation allows flexibility within each phase while preventing unsafe combinations of movements.

AI summary
The present invention is a screen rotation quick release structure. One end of an adapter member is connected to a support frame. One end of a positioning pin protrudes from the other end of the adapter member, and the positioning pin is positioned inside the adapter member in a reciprocating way. A hinge module comprises a first pivoting shaft and a second pivoting shaft. A gap between proximal ends of the first and the second pivoting shafts is provided for accommodating the one end of the positioning pin. A first buckling ring is accommodated and positionally constrained in a clamping space of a top base. An inner ring surface of the first buckling ring has a first and a second engaging grooves. The first and the second engaging grooves are respectively corresponding to distal ends of the first and the second pivoting shafts.
