Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge structures for adjacent boards are complex, costly, and require troublesome installation, often involving metal components.
Innovation Solution
An integrated hinge structure for plastic boards, comprising an embedded groove hinge that divides a first board into two turning portions, allowing them to be rotatable and perpendicular, with stopper features to prevent collapse and a detachable connection mechanism using pins and sockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional metal hinge structures are used to connect adjacent boards, then the connection strength and reliability are improved, but the device complexity, manufacturing cost, and installation difficulty increase
Solution Approach 1:
The patent merges the hinge function directly into the plastic board structure by forming an embedded groove hinge through injection molding. This integrates the hinge mechanism and the board into a single component, eliminating the need for separate metal hinge parts while maintaining the rotational connection function between adjacent boards.
Solution Approach 2:
The patent replaces the traditional mechanical hinge system (metal hinges, screws, and fasteners) with an integrated plastic structure. The embedded groove hinge formed by injection molding provides the rotational mechanism without requiring separate mechanical components, thereby simplifying the overall structure and reducing manufacturing complexity.
2Strength
If traditional metal hinge structures are used to connect adjacent boards, then the connection strength and reliability are improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the hinge function directly into the plastic board structure by forming an embedded groove hinge through injection molding. This integrates the hinge mechanism and the board into a single component, eliminating the need for separate metal hinge parts while maintaining the rotational connection function between adjacent boards.
Solution Approach 2:
The patent uses a plastic-based hinge structure that is cheaper to manufacture than metal hinges. The embedded groove hinge is formed through injection molding, which is a cost-effective manufacturing process for plastic components, thereby reducing the overall manufacturing cost compared to traditional metal hinge assemblies.
3Strength
If traditional metal hinge structures are used to connect adjacent boards, then the connection strength and reliability are improved, but the installation process becomes troublesome and time-consuming
Solution Approach 1:
The patent merges the hinge function directly into the plastic board structure by forming an embedded groove hinge through injection molding. This integrates the hinge mechanism and the board into a single component, eliminating the need for separate metal hinge parts while maintaining the rotational connection function between adjacent boards.
Solution Approach 2:
The patent designs the embedded groove hinge to be self-aligning and self-locking. The groove structure automatically guides the connection between adjacent boards during assembly, and the integrated design eliminates the need for separate fastening operations, thereby significantly reducing installation time and complexity.
4Strength
If traditional metal hinge structures are used to connect adjacent boards, then the connection strength and reliability are improved, but the use of metal components increases cost and complexity
Solution Approach 1:
The patent extracts the metal hinge components from the connection system and replaces them with an integrated plastic structure. The embedded groove hinge is formed directly in the plastic board through injection molding, eliminating the need for separate metal hinge parts while maintaining the rotational connection function.
Solution Approach 2:
The patent uses plastic material with reinforced properties to create the embedded groove hinge structure. The injection-molded plastic structure provides sufficient strength and durability for the hinge function without requiring metal components, thereby reducing material complexity and cost.

AI summary
The present subject matter discloses an integrated hinge structure for plastic boards. The integrated hinge structure has a simplified design that is screw-free and convenient to assemble. It also has a relatively lower manufacturing cost. The integrated hinge structure can comprise a first board and a second board that can be coupled to each other. Furthermore, the first board is divided into a first turning portion and a second turning portion by an embedded groove hinge. The second turning portion is further detachably connected to the second board. The integrated hinge structure further comprises fixation features to render the constructed assembly stable and durable.
