Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floorboards face issues with poor humidity resistance and anti-aging, leading to swelling, warping, and deformation, and their connecting structures are complex, prone to damage, and lack stability during installation and thermal expansion.
Innovation Solution
A floorboard unit with a connecting post featuring a hooking part of approximate trapezoidal structure and an introduction sloping face, which allows for a simple, stable, and locking mechanism that provides tension and accommodates thermal expansion, along with a floorboard connecting base with a step block and installation groove for secure clamping without glue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lock connection method is used to avoid glue and reduce pollution, then environmental friendliness is improved, but the connecting structure becomes complex and prone to damage during installation
Solution Approach 1:
The connecting post is divided into distinct functional segments: a body portion embedded in the floorboard, a hooking part for engagement, and an introduction sloping face for guidance. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure simple and robust.
Solution Approach 2:
Instead of using a complex interlocking mechanism or adhesive systems, the patent inverts the approach by using a simple hooking part that engages with the base through a sloping face. The installation process is inverted from precise alignment to a drop-in method where the sloping face guides the connecting post into place automatically.
2Ease of operation
If a simple structure is used to simplify installation, then ease of installation is improved, but the splicing structure is not strong enough and may deform after long-term use
Solution Approach 1:
The introduction sloping face is designed as a convex arc face rather than a flat surface. This curvature provides a gradual transition that guides the connecting post smoothly into the installation groove, distributing forces evenly and preventing sudden impacts that could cause deformation or failure during installation and use.
Solution Approach 2:
The hooking part is designed with an asymmetric trapezoidal structure where one side is longer than the other. This asymmetry creates a directional engagement mechanism that provides strong locking in the installation direction while maintaining ease of insertion, ensuring both simplicity and structural strength.
3Adaptability or versatility
If enough expansion and contraction space is left for thermal expansion, then adaptability to temperature changes is improved, but the overall structure stability is compromised
Solution Approach 1:
The hooking part is designed with a specific included angle (β) between 90° and 135° that optimizes the balance between providing expansion space and maintaining structural stability. This parameter optimization allows the connection to accommodate thermal movement while preventing excessive gaps or instability in the overall floor structure.
Solution Approach 2:
The connecting structure is designed to be dynamically adaptable rather than rigidly fixed. The hooking part can rotate and adjust within a limited range, allowing the floorboards to expand and contract with temperature changes while maintaining continuous contact and structural integrity throughout the installation.

AI summary
A floorboard unit and a floorboard connecting structure are disclosed in the application. The floorboard unit includes a floorboard body and a connecting post. The connecting post is located at an end edge of a lower surface of the floorboard body, and an end of the connecting post is provided with a hooking part folded in a direction toward an end of the floorboard body, and the hooking part is of an approximate trapezoidal structure, and the hooking part is provided with an introduction sloping face for auxiliary clamping. The floorboard connecting structure according to the disclosure is of a locking type, so it can be paved without glue due to a locking force, which is safe and environment-friendly. A whole structure may extend all around with change of temperature, and there will be no problems such as uplift or cracking due to the change of temperature.
