Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rebar positioning devices for concrete forming lack adjustability, which hinders flexibility in accommodating varying form panel configurations and rebar spacings, potentially leading to improper rebar positioning and reduced concrete strength.
Innovation Solution
A rebar positioning device featuring a support rod with a threaded outer surface and adjustable bar clips that can rotate to change their position and orientation, allowing for customizable rebar placement and integration with interlockable clips for enhanced adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed rebar positioning devices are used, then device structure is simple, but adaptability to varying form panel configurations and rebar spacings is poor
Solution Approach 1:
The patent applies the dynamics principle by making the bar clip position adjustable along the support rod. The bar clip can be moved to different locations on the support rod to accommodate varying rebar spacings and form panel configurations, transforming a static positioning device into a dynamic one that adapts to different construction requirements.
Solution Approach 2:
The patent implements universality by designing a support rod with multiple notches that can accommodate bar clips at various positions. This single device structure can serve multiple functions by adjusting the bar clip location, allowing one device to handle different rebar spacing requirements and form panel configurations rather than requiring multiple fixed-position devices.
2Ease of operation
If adjustable bar clips are used, then positioning flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the support rod into multiple sections with notches at different positions. Each notch represents a discrete positioning option for the bar clip, allowing easy adjustment to different rebar spacing requirements while maintaining a relatively simple overall device structure.
Solution Approach 2:
The bar clip design incorporates a breakable feature where the clip can be snapped off the support rod after use. This allows for quick disposal of the clip while retaining the reusable support rod, simplifying the adjustment process for different positioning requirements without requiring complex retention mechanisms.

AI summary
A rebar positioning device with opposite ends for positioning adjacent to a form face of at least one form panel may include a support rod having opposite ends and an outer surface, with at least a portion of the outer surface being threaded. At least one bar clip may be movably mounted on the support rod. An orientation of the at least one bar clip on the support rod is adjustable, and a position of the at least one bar clip on the support rod is adjustable.
