Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic adsorption is used to fix display modules, then disassembly and maintenance become quick and convenient, but the connection becomes unstable and modules are prone to falling under windy conditions
Solution Approach 1:
The patent combines magnetic adsorption with a mechanical locking system. The locking mechanism includes locking blocks that engage with locking grooves on the display frame, while magnets provide additional holding force. This merging of magnetic and mechanical locking methods achieves both easy disassembly (by releasing the mechanical lock) and high stability (through combined magnetic and mechanical retention).
Solution Approach 2:
The fixing system uses composite fixing components that integrate magnetic elements with mechanical locking structures. The fixing component includes a locking block with a locking end that engages the locking groove, and magnetic elements embedded within the structure. This composite design provides both the mechanical interlocking for stability and magnetic attraction for enhanced holding force and easy release.
2Reliability
If screw fixation is used to fix display modules, then connection stability improves and modules are resistant to wind, but disassembly and maintenance become troublesome and time-consuming
Solution Approach 1:
The locking mechanism is segmented into a locking block with a locking end and a locking groove on the display frame. The locking block can be quickly engaged with or disengaged from the locking groove by sliding or rotating motion, eliminating the need for screw operations. This segmentation allows the fixing function to be separated from the time-consuming screw tightening process.
Solution Approach 2:
The patent replaces the screw fixation mechanical system with a sliding or rotating locking mechanism. Instead of using threads and torque application, the system uses a locking block that engages with a locking groove through simple linear or rotational motion. This substitution maintains mechanical stability while dramatically reducing the time and complexity of disassembly operations.
3Reliability
If a safety rope is added behind display modules to prevent falling, then connection stability improves, but the appearance becomes unsightly
Solution Approach 1:
The patent extracts the safety function from the external safety rope and integrates it into the display module structure itself. The locking mechanism with locking blocks and locking grooves, combined with magnetic adsorption, provides inherent anti-falling capability built into the module design. This eliminates the need for external safety ropes that would compromise appearance, as the safety function is now embedded within the module's structure.

AI summary
The present application discloses a display screen, including a display frame, a detachable display module connected to the display frame, and a locking mechanism mounted on the back of the display module for locking the display module to the display frame. The display frame has at least two frame bars arranged in a row and at intervals, and any two adjacent frame bars are provided with at least two engaged grooves spaced opposite to each other. The locking mechanism includes two telescopic rods and a drive assembly for driving the two telescopic rods to be inserted into or pulled out from the engaged grooves arranged on the two frame bars, respectively. The drive assembly is installed on the back of the display module and connected to the two telescopic rods. The display screen disclosed in the present application has the advantages as follows: The connection between the display module and the display frame is firm, and the disassembly and installation of the display module and the display frame is straightforward and convenient.
