Integrated Siding Splice Joint for Fast Waterproof Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing siding splice joints require numerous screws to connect, leading to cumbersome and error-prone assembly, with potential for screws to be dropped and lack of anti-slip and waterproof functionality, resulting in poor alignment and additional waterproofing needs.
Innovation Solution
A siding splice joint design featuring a body with injection-molded washers and screws, where washers provide anti-slip and waterproofing, and screws are directly connected to the body for quick assembly, preventing accidental dropping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to connect siding splices, then the connection strength is improved, but the ease of operation deteriorates due to cumbersome handling and risk of dropping screws
Solution Approach 1:
The patent combines multiple screws and washers into a single integrated connector body. The body contains multiple through-holes with washers pre-installed, and multiple screws are stored within cavities of the body. This merging eliminates the need to handle multiple loose screws and washers separately, while still providing multiple connection points for strong attachment of siding splices.
Solution Approach 2:
The washers are pre-installed on the through-holes of the body during manufacturing, and screws are pre-stored in the cavities. This preliminary preparation eliminates the need for users to manually install washers or search for screws during assembly, significantly improving ease of operation while maintaining strong connection capability.
2Ease of manufacture
If the body is made simple for easy connection, then the ease of manufacture is improved, but the reliability deteriorates due to lack of anti-slip and waterproof functions
Solution Approach 1:
The body is segmented into functional zones: connection portions with through-holes for mechanical attachment, waterproof portions that extend into grooves to seal interfaces, and anti-slip portions with textured surfaces. This segmentation allows each zone to perform its specific function effectively while maintaining an integrated structure that is relatively easy to manufacture as a single piece.
Solution Approach 2:
Different portions of the body have different local properties: the connection portions have precise holes for screw attachment, the waterproof portions have smooth surfaces that fit into grooves, and the anti-slip portions have textured or patterned surfaces. This local differentiation of qualities enables the body to provide multiple functions (strong connection, waterproofing, anti-slip) without requiring complex assembly of multiple components.

AI summary
A siding splice joint contains: a body, multiple washers, and multiple screws. The body includes a first face, a second face, and multiple through holes. A respective washer is injection molded on a respective through hole and includes a thin portion, a thick portion, a connection portion, and a lock orifice. The thick portion of the respective washer is connected on the first face, the thick portion of the respective washer is connected on the second face, and the connection portion is inserted through the respective through hole. A respective screw includes a head, an extension shank integrally extending from the head, and a tip formed on the extension shank away from the head. The extension shank is screwed in the locking orifice of the respective washer so that the respective screw is not locked on but connected with the respective washer.
