Self-Locking Wallboard Structure With Controlled Expansion Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wallboards in construction require a direct gap reservation between them, which is uncontrollable and relies on constructor experience, leading to issues like bulges or aesthetically undesirable joints due to improperly sized gaps.
Innovation Solution
A wallboard with a self-locking function and pre-expansion space, featuring a strip-shaped groove and bulge design with a three-layer structure, including a spring-type insertion strip and guide columns, allowing for controlled gap adjustment and expansion to prevent joint raising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gap is reserved between wallboards for expansion, then the wallboard can expand without causing bulges, but the gap size becomes uncontrollable and relies on constructor experience
Solution Approach 1:
The wallboard structure incorporates self-locking grooves and protrusions that automatically control the gap size during installation. The mechanical interlocking mechanism allows the wallboard to self-adjust and maintain the proper expansion gap without requiring constructor judgment or experience, thus achieving self-service functionality.
Solution Approach 2:
The patent introduces specific geometric parameters through the groove and protrusion design, including the inclined surface angle and the dimensions of the self-locking structures. These parameter changes transform the uncontrollable gap into a precisely controlled dimension determined by the manufactured features rather than human judgment.
2Ease of operation
If a small gap is reserved between wallboards, then installation is easier, but joint bulges form during expansion causing unqualified construction
Solution Approach 1:
The wallboard design incorporates pre-formed grooves and protrusions that create a predetermined expansion space before installation. This preliminary action ensures that sufficient gap is reserved in advance through the mechanical structure, preventing joint bulges during expansion while maintaining consistent quality without relying on constructor experience.
3Reliability
If a large gap is reserved between wallboards, then expansion is accommodated, but aesthetic impact deteriorates due to excessive spacing
Solution Approach 1:
The self-locking groove and protrusion design establishes precise geometric parameters that control the gap to an optimal size. This parameter control ensures the gap is large enough to accommodate expansion but small enough to maintain aesthetic appearance, eliminating the need to choose between excessive spacing and insufficient space.
4Shape
If no gap is reserved between wallboards, then the connection appears seamless and aesthetic, but expansion causes joint bulges and structural failure
Solution Approach 1:
The groove and protrusion features are nested within the wallboard edges, creating a hierarchical structure where the self-locking mechanism is integrated into the overall wallboard design. This nesting allows the expansion gap to be concealed within the structural features, maintaining seamless appearance while providing necessary expansion space for structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures firm and aesthetically pleasing connections by optimizing gap size and allowing the wallboard to expand and fill gaps, preventing joint bulges through the use of a self-locking mechanism.
Implementation Method 1
a self-locking structure matched is arranged on the strip-shaped bulge and the first strip-shaped groove; a lower part of the strip-shaped bulge is an inclined surface, and an angle between the inclined surface and a lower surface of the strip-shaped bulge is an acute angle; an upper part of the strip-shaped bulge is a vertical surface; a second strip-shaped groove is provided in a position, adjacent to the inclined surface, of the lower board surface; two side edges of the second strip-shaped groove are both provided with inclined structures and have the same inclination angle as the inclined surface
Implementation Method 2
the self-locking structure is a spring type insertion strip; a step is arranged on an outermost side of a lower part of the first strip-shaped groove; the insertion strip is arranged on the step and is fixed to the step by a plurality of springs; an upper part of the insertion strip protrudes into the first strip-shaped groove in a natural state of the springs
