Parapet Upright Height Adjustment via Sleeve Base Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parapet systems are limited by the need for specific upright cross-sections, high investment in die-casting processes, and inefficient anchoring systems that restrict adaptability and ease of installation, making them costly and difficult to integrate with architectural designs.
Innovation Solution
A parapet system with adjustable uprights supported by feet featuring a sleeve and base portion that allows for longitudinal adjustment, using screws to secure the uprights at varying heights, enabling flexible installation and production from standard extruded components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If die-casting process is used to produce the support, then the support can be manufactured with complex geometry, but the production cost and investment requirements increase significantly
Solution Approach 1:
The patent replaces expensive die-casting with cheaper extrusion and machining processes. The support is manufactured using standard extruded profiles that are then machined to final dimensions, eliminating the need for expensive dies and tooling while reducing production costs and investment requirements.
Solution Approach 2:
The patent changes the manufacturing parameters from die-casting to extrusion and machining. This allows the use of standard extruded aluminum profiles with consistent cross-sections that can be easily machined, rather than requiring complex die-casting processes for each unique support geometry.
2Reliability
If uprights with specific cross-sections are required, then the connection with the support can be secure, but the adaptability to different architectural designs is restricted
Solution Approach 1:
The patent creates a universal support system that can accommodate various upright cross-sections. The support is designed with a standardized interface that can securely connect different types of uprights (square, rectangular, circular, or other profiles) through machining operations, allowing the same support to serve multiple architectural designs and upright types.
Solution Approach 2:
The patent separates the connection function into two independent components: the standardized support with its machined interface and the various upright profiles. This segmentation allows the support to remain unchanged while accommodating different upright types, enhancing versatility without compromising connection reliability.
3Shape
If the parapet system requires custom-cut bars with specific ribs, then the aesthetic results can be optimized, but the installation complexity and equipment requirements increase
Solution Approach 1:
The patent performs all necessary cutting, shaping, and rib formation operations during the extrusion and machining processes at the factory. The uprights are pre-formed with their final geometry, ribs, and connection features before shipment, eliminating the need for on-site cutting equipment and complex installation procedures while maintaining aesthetic quality.
Solution Approach 2:
The extrusion and machining processes inherently create the required ribs and geometric features as part of the standard manufacturing process. The uprights are self-sufficient with all necessary connection features and aesthetic elements already integrated, requiring no additional on-site fabrication or specialized installation equipment.
4Ease of manufacture
If the upright height is fixed, then the manufacturing process is simplified, but the adaptability to different installation heights is reduced
Solution Approach 1:
The patent introduces adjustability into the upright-s support connection through machined interfaces that allow vertical positioning. The support includes threaded holes or slots that enable the upright to be secured at multiple height positions, transforming the system from fixed to adjustable while maintaining manufacturing simplicity through standard machining operations.
