Interlocking Construction Profiles That Preserve Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction structures face challenges in maintaining structural integrity and efficiency due to deformation issues, particularly when using mixed auxiliary structures with perpendicular profiles, which require numerous joint pieces and increase installation time and cost, while compromising the moment of inertia and load capacity.
Innovation Solution
A profile system that joins primary and secondary profiles without the need for additional joint pieces, maintaining continuity by aligning perforations near the neutral fiber and elevating secondary profile support points, allowing for a durable and efficient coupling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mixed auxiliary structures with perpendicular profiles are used to support large loads or large spans, then the load capacity and span capability are improved, but the number of joint pieces increases significantly, increasing installation time and cost
Solution Approach 1:
The patent merges the joint piece function into the profile itself by integrating locking mechanisms directly into the C-shaped and U-shaped profile structures. This eliminates separate joint pieces while maintaining the mixed auxiliary structure's load capacity and span capability.
Solution Approach 2:
The profile design incorporates multiple functions within single structural elements - the C-shaped and U-shaped profiles simultaneously provide structural support, connection, and positioning functions, reducing the need for specialized joint pieces for each connection type.
2Ease of operation
If perforations are made in primary profiles to facilitate secondary profile fixing, then the ease of installation is improved, but the moment of inertia and load capacity of primary profiles are reduced
Solution Approach 1:
The patent applies local quality by making perforations only in the web of the C-shaped profile (the vertical section), avoiding perforations in the wings (horizontal sections) where the moment of inertia is most critical. This localized approach allows easy secondary profile fixing while preserving the primary profile's structural integrity.
3Strength
If the bottom of primary and secondary profiles are at the same level to improve mechanical behavior, then the rigidity is improved, but the profiles interfere with each other, requiring more complex joint solutions
Solution Approach 1:
The patent resolves the interference issue by using the vertical dimension - the C-shaped profile extends below the U-shaped profile level, creating a stepped arrangement. This dimensional differentiation eliminates interference while maintaining rigidity through the integrated locking mechanism that connects profiles at different levels.
4Manufacturing precision
If adjustment of profile separation is carried out during installation to prevent separation, then the positioning accuracy is improved, but the installation time increases
Solution Approach 1:
The patent incorporates preliminary action by including adjustment features (such as adjustable positioning elements) in the profile design that allow for quick separation adjustment during installation. This preliminary design of adjustment capabilities enables both accurate positioning and reduced installation time by eliminating complex post-installation adjustments.
