Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available presentation boards have complex structures, limited flexibility, and are inconvenient to assemble and disassemble, making them unsuitable for adapting to market demands.
Innovation Solution
A modularized presentation board system with rectangular modules, plug connectors, and articulation pieces featuring 45-degree chamfers, clamping slots, and reinforced ribs, allowing for easy assembly and disassembly, and enabling connection at various angles through annular bulges and strip-shaped grooves, with optional support uprights or rollers for mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a modularized design with simple structures is adopted, then ease of assembly and flexibility are improved, but structural strength and stability may deteriorate
Solution Approach 1:
The presentation board is divided into multiple independent modules that can be assembled together. Each module has standardized connection interfaces (plug connectors and articulation pieces) that enable easy assembly while maintaining structural integrity through the modular architecture.
Solution Approach 2:
The connection structure combines multiple material properties: the plug connectors and articulation pieces use reinforced ribs and nested grooves to create composite joints that provide both ease of assembly and structural strength through the combination of mechanical interlocking and material reinforcement.
2Ease of operation
If a modularized design with simple structures is adopted, then convenience of transportation is improved, but connection reliability may deteriorate
Solution Approach 1:
The board segments into transportable modules with standardized connectors. The articulation pieces with hinges allow folded configurations for compact transport, while the plug connectors ensure reliable reassembly through precise nested groove and bulge interfaces.
Solution Approach 2:
The plug connectors feature nested grooves and bulges where one component fits into another. This nesting mechanism provides reliable connection through progressive engagement of multiple nested features, ensuring connection reliability while maintaining modular portability.
3Stability of the object's composition
If fixed-angle connections are used, then structural stability is improved, but adaptability to different presentation styles deteriorates
Solution Approach 1:
The articulation pieces incorporate hinges that enable dynamic adjustment of connection angles. This allows the structure to transition between stable fixed configurations and adaptable intermediate positions, providing both structural stability when needed and flexibility for different presentation styles.
Solution Approach 2:
The standardized plug connectors and articulation pieces serve multiple functions: they provide stable fixed-angle connections for structural integrity, enable adaptable angle adjustments for different presentation configurations, and allow the same components to be used across various module combinations.
4Strength
If complex structures are used in presentation boards, then structural strength is improved, but device complexity and ease of assembly deteriorate
Solution Approach 1:
The complex structure is segmented into standardized modules with simplified individual components. Each module maintains necessary structural strength through localized reinforcement ribs and properly designed connection interfaces, while the overall system complexity is reduced through standardization and modularity.
Solution Approach 2:
Complexity and reinforcement are concentrated locally at the connection points (plug connectors and articulation pieces) where structural strength is most needed. The majority of the module bodies remain simple and lightweight, achieving overall structural strength without universal complexity.

AI summary
A modularized presentation board includes multiple rectangular presentation board modules, multiple plug connectors and multiple articulation pieces; 45-degree chamfer structures are arranged at four corners of each presentation board module, a clamping slot is configured in the middle of each of four corners in the thickness direction, multiple strip-shaped bulges and multiple reinforced ribs perpendicular to the strip-shaped bulges are respectively arranged on both sides of each clamping slot, and a groove is defined between every two adjacent reinforced ribs; and the plug connectors and the articulation pieces are equipped with multiple annular bulges, respectively, and thus nested and matched connection between every two adjacent presentation board modules is realized.
