Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional anti-peeping display device uses a fixed louver structure, then the manufacturing process is simple and cost is low, but the visual angle is fixed and non-adjustable, limiting adaptability to different usage scenarios
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed louver structure into a dynamic, adjustable structure. The louver layer is positioned between two substrates that can move relative to each other in the thickness direction, allowing the visual angle to be adjusted dynamically. This enables the same structure to adapt to different usage scenarios without requiring redesign, resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
The patent implements parameter changes by modifying the distance between the two substrates in the thickness direction. By changing this physical parameter, the degree of compression of the louver layer is adjusted, which directly controls the visual angle. This allows a single structure to achieve multiple visual angle settings through parameter adjustment rather than structural redesign.
2Adaptability or versatility
If the visual angle of a conventional anti-peeping display device is changed, then a new louver structure must be redesigned and assembled, but this results in complicated modification processes and high manufacturing costs
Solution Approach 1:
The dynamic adjustment mechanism allows visual angle customization without requiring a new louver structure to be manufactured. The same louver layer can be adjusted to different visual angles by changing the substrate distance, eliminating the need for complicated redesign and reassembly processes for different visual angle requirements.
Solution Approach 2:
The patent creates a universal structure that can serve multiple visual angle requirements. The adjustable mechanism allows a single device to perform multiple functions (different visual angles) without requiring separate structures for each function, thereby simplifying manufacturing and reducing costs.
3Ease of operation
If drive modules are added to enable substrate movement and louver layer deformation, then visual angle adjustment is achieved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical drive systems with magnetic components. Electromagnets are used to generate the forces needed to move the substrates and deform the louver layer, eliminating the need for mechanical linkages, gears, or motors. This substitution reduces assembly complexity while maintaining ease of operation through electrical control.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary to transmit the control signal from the electromagnets to the substrates. This intermediary mechanism allows for smooth, contactless actuation of the substrates, simplifying the overall system while enabling precise visual angle control.

AI summary
An anti-peeping assembly and an anti-peeping display device. The anti-peeping assembly includes an anti-peeping component, two frames arranged at a periphery of the anti-peeping component, and two drive modules. The anti-peeping component includes two first substrates and a louver layer sandwiched between the two first substrates. The louver layer includes a plurality of light transmitting parts and a plurality of shading parts adjacent to the plurality of light transmitting parts. The drive module is configured to drive at least one of the two first substrates to move relative to the louver layer in a thickness direction of the first substrates so as to cause the louver layer to be compressed or be recovered from deformation, thereby realizing adjustment of a dimension of each of the light transmitting parts in the thickness direction. The anti-peeping assembly solves a problem that the conventional anti-peeping assembly has fixed and non-adjustable visual angle.
