Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the internal structure design of the near-eye display module is conventional, then the structural stability is maintained, but the volume and weight become relatively large, making it inconvenient for long-term wearing
Solution Approach 1:
The patent applies dimensionality change by transforming the flat two-dimensional circuit board structure into a three-dimensional folded structure. The circuit board is folded along specific fold lines to create a multi-layer spatial configuration, allowing components to be arranged in different vertical levels. This three-dimensional arrangement significantly reduces the overall footprint and volume of the near-eye display module while maintaining all necessary electrical connections and component functions, thereby improving wearing comfort.
2Weight of stationary object
If the internal structure design of the near-eye display module is conventional, then the assembly is straightforward, but the weight becomes relatively heavy
Solution Approach 1:
The patent implements nesting by placing the storage assembly inside the accommodation space formed by the folded circuit board structure. The storage assembly, which contains memory chips and other components, is positioned within the three-dimensional space created by the folded layers of the circuit board. This nested arrangement eliminates the need for separate housing structures and reduces overall material usage, thereby decreasing weight while maintaining structural integrity and component protection.
3Volume of moving object
If the internal structure design of the near-eye display module is optimized for compactness, then the volume and weight are reduced, but the complexity of the structure increases
Solution Approach 1:
The patent applies segmentation by dividing the circuit board into multiple distinct sections separated by fold lines. Each section can be independently designed, manufactured, and assembled. The folded structure creates discrete spatial zones that accommodate different components (display assembly, storage assembly, processing units) in an organized manner. This segmented approach simplifies the manufacturing process and assembly procedures while achieving compact volume, as each segment can be optimized independently and then integrated through the fold lines.

AI summary
A near-eye display module and a near-eye display device are provided. A housing defines an installation space, and the control plate assembly is located in the installation space. The control plate assembly includes a main control plate and an adapter plate. A display assembly includes a first base, a second base, and a micro-display. The storage assembly is electrically connected to the display assembly. The storage assembly includes a second plate body, a first plate body, and a storage chip. The first plate body is configured to be non-parallel to the second plate body after folding a fifth fold section. The adapter plate is configured to at least partially overlap with the main control plate after folding a first fold section in a first direction. The second base is configured to at least partially overlap with the first base after folding the fourth fold section in the first direction.
