Adjustable Formwork Device for Concrete Slab Height Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork devices for concrete slabs are limited to standardized dimensions, particularly vertical dimensions, making it difficult to accommodate variations in concrete slab thickness, and lack the ability to adjust height according to construction needs.
Innovation Solution
A formwork device with adjustable height features, including interlocking profiled support bases, brackets for vertical plates, oblong slots for height adjustment, and a lifting mechanism with a control arm and platform, allowing for fine adjustments and inclination, enabling the device to accommodate varying concrete slab thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If formwork devices are designed with standardized dimensions, then manufacturing and operation become simpler, but the ability to accommodate variations in concrete slab thickness is lost
Solution Approach 1:
The patent implements height adjustability through movable support legs with extension mechanisms, allowing the formwork device to dynamically adapt its vertical dimension. The support legs can be extended or retracted to accommodate different concrete slab thicknesses, transforming a static standardized structure into a dynamic adaptable system.
Solution Approach 2:
The invention changes the vertical parameter (height) of the formwork device by providing adjustable support legs with multiple position settings. This allows the same device to operate at different heights depending on the required concrete slab thickness, resolving the contradiction between standardization and adaptability.
2Device complexity
If formwork devices are designed with fixed dimensions, then device complexity is reduced, but the capacity to adjust height according to construction needs is eliminated
Solution Approach 1:
The formwork device is segmented into modular components, with support legs that can be independently adjusted. Each support leg functions as a separate adjustable unit, allowing height modification without redesigning the entire structure. This segmentation enables adaptability while keeping individual components relatively simple.
Solution Approach 2:
The support legs incorporate extension mechanisms that enable dynamic height adjustment. These mechanisms allow the support legs to change length within a defined range, providing the necessary height variation capability while maintaining a relatively simple overall device structure through straightforward mechanical extensions.
3Productivity
If formwork devices use standardized vertical dimensions, then production and inventory management become easier, but the ability to accommodate varying concrete slab thicknesses is compromised
Solution Approach 1:
The formwork device achieves multi-functionality through its adjustable support legs, enabling a single standardized device design to serve multiple height requirements. The same device can be used for different concrete slab thicknesses by adjusting the support leg extensions, eliminating the need for multiple specialized devices and improving productivity.
