Interlocking Corner Molding Assembly for Siding and Roofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner moldings for siding and roofing coverings are aesthetically unaesthetic, cumbersome to assemble, and not adaptable to a range of corner angles, requiring different moldings for inside and outside corners.
Innovation Solution
A corner assembly comprising two complementary molding members with interlocking protruding fingers and recesses, capable of configuring into inside and outside corners, featuring identical design for ease of use and adaptability, with U-shaped wall extensions for vertical stacking and fastening flanges for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional corner moldings are used, then the corner joints are hidden, but the aesthetic appearance is compromised and assembly becomes cumbersome
Solution Approach 1:
The corner molding is divided into two separate complementary members (first and second corner molding members) that can be independently manufactured and then assembled together. Each member has simplified geometry with protruding fingers and recesses that enable easy interlocking assembly, eliminating the need for complex pre-assembled corner units.
Solution Approach 2:
The protruding fingers and recesses act as intermediary coupling elements between the two corner molding members. These features facilitate the assembly process by providing mechanical interlocking capability, making the corner assembly straightforward without requiring complex fastening mechanisms.
2Adaptability or versatility
If different corner moldings are used for inside and outside corners, then specific corner types are covered accurately, but the number of required molding types increases
Solution Approach 1:
The same two corner molding members can be configured to form both inside corners and outside corners by changing their relative positioning and orientation during assembly. This universal design eliminates the need for separate molding types for different corner configurations, reducing inventory requirements.
Solution Approach 2:
The corner molding system is designed to be dynamically configurable rather than statically fixed. The two members can be assembled in different orientations and configurations to adapt to various corner types (inside or outside corners at different angles), providing versatility through flexible assembly rather than through multiple specialized components.
3Ease of manufacture
If corner moldings are designed for predefined angles, then manufacturing is simplified, but adaptability to various corner angles is limited
Solution Approach 1:
The corner molding members are designed with flexible angular configuration capability. The protruding fingers and recesses allow the two members to be joined at various angles while maintaining structural integrity, enabling the same components to adapt to different corner angles without requiring angle-specific tooling or manufacturing processes.

AI summary
A corner assembly for siding and roofing coverings includes two complementary corner molding members, each one of the two corner molding members having a front wall including a covering section with simulated building elements on an outer face thereof. Each one of the two corner molding members further has at least one protruding finger and at least one recess. The at least one protruding finger and at least one recess are configured in an alternate configuration in order to interlock in a male-female configuration when the two complementary corner molding members are engaged with one another to define a corner. A method covers a length of a corner defined at a junction of a first support surface and a second support surface.
