Twist-Proof Telescoping Formwork Support for Fast Bolt Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork supports face challenges with twisting during telescoping, leading to alignment difficulties, increased complexity, weight, and manufacturing costs, as well as requiring manual handling due to the need for precise orientation and securing bolt alignment.
Innovation Solution
A formwork support design featuring a twist-proof region with a first inner contour and a guide region with a second inner contour, where the twist-proof region blocks rotation while allowing longitudinal displacement, simplifying alignment and locking by ensuring consistent orientation and facilitating easy telescoping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex anti-twist device is added to prevent twisting during telescoping, then twisting is blocked and alignment is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the anti-twist function with the existing telescoping structure by integrating twist-proof portions into the inner support part and twist-proof regions into the outer support part. The contour shapes of these regions inherently provide both telescoping guidance and twisting prevention, merging multiple functions into a unified structure rather than adding separate anti-twist devices.
Solution Approach 2:
The patent applies different contour shapes to different regions of the support parts. The twist-proof region has a first inner contour that differs from the guide region's second inner contour. This local differentiation allows the structure to provide both smooth telescoping in the guide region and twisting prevention in the twist-proof region, optimizing each zone for its specific function.
2Device complexity
If manual alignment and securing bolt insertion is required without anti-twist devices, then device complexity is reduced, but setup time and labor intensity increase
Solution Approach 1:
The patent pre-configures the inner and outer support parts with complementary twist-proof portions and regions having specific contour shapes. This preliminary design ensures that when the inner support part is inserted into the outer support part, the contours automatically guide alignment and prevent twisting, eliminating the need for manual alignment adjustments and accelerating the setup process.
Solution Approach 2:
The contour-shaped twist-proof regions enable the formwork support system to self-align and self-constrain during telescoping. The geometric interlocking of the inner and outer support part contours automatically performs the alignment function that would otherwise require manual intervention, making the system self-servicing during assembly.
3Ease of manufacture
If securing holes are provided without anti-twist features, then manufacturing is simplified, but precise bolt alignment becomes difficult and time-consuming
Solution Approach 1:
The patent employs asymmetric contour shapes in the twist-proof regions that are specifically designed to guide the inner support part into a precise rotational position relative to the outer support part. This asymmetric geometric constraint ensures that securing holes automatically align when the telescoping components are assembled, eliminating the need for additional alignment features while maintaining high precision.
