Interlocking Plastic Panel Structure for Orientation-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modular plastic panels require careful orientation during construction due to asymmetrical engaging portions, limiting their functionality and increasing construction time, as they can only be connected when one panel faces up and the other down, restricting their application in various space and environmental conditions.
Innovation Solution
A plastic panel design featuring complementary engaging portions on both sides, allowing for connection regardless of orientation, with extension sections and recesses that enable secure engagement and facilitate drainage, decoration, and ventilation, while supporting ribs enhance structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional modular panels use asymmetrical engaging portions, then the panels can be connected when oriented in specific directions, but the construction time increases and functionality is limited due to orientation requirements
Solution Approach 1:
The patent applies asymmetry by designing the engaging portions with distinct convex and concave features that are asymmetrically arranged on each panel. However, the key innovation is that both sides of each panel have identical asymmetrical engaging portions, allowing the panel to be connected regardless of which side faces up, thereby eliminating orientation requirements during construction
2Reliability
If conventional modular panels use asymmetrical engaging portions, then the panels can be securely connected, but the application options are restricted due to orientation constraints
Solution Approach 1:
The patent achieves universality by designing panels with identical engaging portions on both sides, making the panels multi-functional and adaptable to various installation orientations and application scenarios. The panels can be installed in different configurations (e.g., sloped roofs, flat roofs, vertical walls) without requiring different panel types or orientations, thereby expanding application versatility while maintaining connection reliability
3Ease of manufacture
If conventional modular panels use simple engaging portions, then the manufacturing is easier, but rainwater can intrude through the convex and concave portions
Solution Approach 1:
The patent applies local quality by designing the engaging portions with differentiated features: convex portions with inclined surfaces that slope downward to shed rainwater, and concave portions that are positioned and shaped to minimize water accumulation. This localized design of the engaging portion surfaces provides both secure mechanical engagement and effective rainwater drainage functionality

AI summary
A plastic panel includes a middle portion. Two opposing sides of the middle portion are defined as a first engaging portion and a second engaging portion, respectively. Each engaging portion has a concave portion, a convex portion, a protruding portion and a recess portion. Two adjacent plastic panels can be firmly connected through their concave portions, convex portions, protruding portions and recess portions. Besides, two adjacent plastic panels facing up or facing down can be engaged and connected with each other.
