Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If display panels are installed in multi-display devices, then information display capability is improved, but screen distortion occurs due to height differences between adjacent panels
Solution Approach 1:
The invention divides the adjustment function into separate modular components: a displacement adjustment unit with threaded rod and nut mechanism, and a rotating magnet assembly. This segmentation allows independent adjustment of each display panel's position without affecting others, enabling precise alignment correction for height differences between adjacent panels.
Solution Approach 2:
The invention replaces traditional mechanical fastening systems with a magnetic field-based adjustment mechanism. The rotating magnet interacts with a magnetic rod to produce rotational motion that drives the threaded displacement adjustment unit, eliminating the need for complex mechanical linkages and enabling easier adjustment while maintaining precise positioning.
2Ease of manufacture
If traditional installation methods are used for display panels, then installation process is simple, but adjustment of height differences requires physical detachment and reattachment
Solution Approach 1:
The invention transforms the static installation system into a dynamic adjustable system. The rotating magnet and magnetic rod enable continuous rotational adjustment of the display panel position during operation, allowing real-time correction of height differences without requiring detachment. The threaded rod converts rotational motion into linear displacement for precise positioning.
Solution Approach 2:
The invention introduces a magnetic field as an intermediary between the rotating magnet and the display panel mounting structure. This magnetic intermediary transmits rotational motion through the magnetic rod to the displacement adjustment unit, enabling non-contact force transmission and smooth adjustment without mechanical friction or wear.
3Manufacturing precision
If display panels are repeatedly attached and detached for adjustment, then alignment can be corrected, but damage risk increases
Solution Approach 1:
The invention performs preliminary positioning adjustment through the displacement adjustment unit before final panel attachment. The rotating magnet mechanism allows fine-tuning of panel height and alignment while the panel remains mounted, eliminating the need for repeated detachment and reattachment operations that could cause damage to connectors or mounting structures.
