Support-Rod Head Structure for Wide-Angle Baffle Cloth Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support rods for baffle cloths in construction environments suffer from complex operations, labor inefficiencies, and limited adjustable ranges, leading to potential cloth slippage and damage due to inconsistent angles with ceiling surfaces.
Innovation Solution
A support-rod head structure featuring a connecting base with a rotatable turning base and top plate, combined with a telescopic rod mechanism, allowing for a composite 'clip+universal joint' function, enhanced adjustability, and anti-slip features to secure the baffle cloth effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal joint connection is used between the top plate and telescopic rod, then the support rod can adapt to different ceiling angles, but the operation becomes complex and time-consuming
Solution Approach 1:
The head structure is divided into three independent modules: connecting base, turning base, and top plate. Each module can rotate relative to the others through groove-pinning mechanisms, allowing incremental angle adjustment without complex manual manipulation of a single universal joint.
Solution Approach 2:
The structure transitions from a static universal joint to a dynamic multi-groove system where the top plate can rotate through first, second, and third grooves in sequence. This dynamic segmentation enables continuous angle adjustment while maintaining operational simplicity through a plug-and-play pinning mechanism.
2Ease of operation
If a side clip is used to clamp the baffle cloth, then the installation is simpler, but the adjustable range is limited and the cloth may slip or be damaged
Solution Approach 1:
The turning base serves multiple functions: it acts as a rotational joint for angle adjustment, provides a second groove for additional rotation, and maintains structural support. This multi-functional design replaces the limited side clip while preserving operational simplicity through integrated geometry rather than separate components.
3Stability of the object's composition
If the top plate is rigidly fixed to the telescopic rod, then the structure is stable, but it cannot adapt to different ceiling angles
Solution Approach 1:
The turning base is rotatably mounted within the connecting base through nested grooves and pin shafts. The top plate is similarly nested within the turning base. This nested configuration allows rotational movement while maintaining structural integrity, as each nested interface provides stable mechanical support during rotation.
Solution Approach 2:
The groove-pinning mechanism provides pre-positioned rotational stops at multiple angles (first groove, second groove, third groove). These pre-defined positions cushion the adjustment process by guiding the user to stable equilibrium points, preventing unstable intermediate positions while maintaining adaptability.
4Adaptability or versatility
If a complex universal joint structure is used, then the angle adaptability is improved, but the device complexity increases
Solution Approach 1:
Each groove-pinning interface (connecting base to turning base, turning base to top plate) is designed with localized quality: the grooves are positioned at specific orientations to enable rotation in specific directions. This localized geometric design achieves comprehensive angle adaptability through simple, repetitive local features rather than a complex global mechanism.
