Angle Adjustable Tread Brackets for Staircase Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing staircase construction methods, particularly for custom angles other than 39 degrees, are challenging due to complex calculations and a lack of readily available stringers, leading to potential errors in creating staircases with desired inclinations.
Innovation Solution
An angle adjustable tread holding bracket system comprising a pin hinge mechanism with a U-shaped slot and arcuate groove, allowing adjustment from 30 to 45 degrees, which includes an anchor member for secure attachment to the stringer and a tread plate for easy customization of staircase angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom stringers are made for non-standard angles, then staircase angle customization is achieved, but calculation complexity and error risk increase
Solution Approach 1:
The bracket assembly incorporates a rotational joint that allows the second bracket member to rotate relative to the first, enabling dynamic adjustment of the staircase angle. The arcuate groove with bolt element provides a guided rotation path, transforming the static fixed-angle bracket into a dynamic adjustable system that can accommodate various inclinations without complex calculations
Solution Approach 2:
The invention changes the fixed angular parameter of traditional brackets to a variable parameter system. By providing an arcuate groove with multiple positioning holes and a rotatable second bracket member, the bracket can be adjusted to different angles (e.g., 30, 35, 40, 45 degrees) and locked in place, allowing parameter variation without recalculation
2Adaptability or versatility
If angle adjustable mechanism is added to the bracket, then staircase inclination flexibility is improved, but bracket structure complexity increases
Solution Approach 1:
The bracket is divided into two separate bracket members (first and second) that can rotate independently relative to each other. This segmentation allows the angle adjustment function to be isolated to the rotational joint between members, rather than requiring the entire bracket structure to be complex and adjustable
Solution Approach 2:
The pin hinge member acts as an intermediary element that connects the first and second bracket members, enabling controlled rotation between them. The arcuate groove with bolt element serves as another intermediary that guides and limits the rotational movement, providing a simple mechanical solution for angle adjustment without complex mechanisms
