Wire Binding Apparatus with Adjustable Space Defining Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding apparatuses for reinforcing bars in concrete constructions face challenges in achieving consistent wire tension, often resulting in either loose or broken bindings due to variations in bar angles and protrusions, leading to inconsistent binding quality and increased costs.
Innovation Solution
A binding apparatus with adjustable space defining elements that vary the distance from objects to the binding tool based on torque, axial pressure, and tension, ensuring a predetermined number of twists and optimal wire tension, regardless of object size or protrusion position, to maintain consistent binding quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wire is twisted as many times as possible to ensure sufficient binding strength, then the binding strength is improved, but the binding time increases excessively
Solution Approach 1:
The patent changes the parameter of wire twisting from an indefinite process ('as many times as possible') to a controlled process with a predetermined number of twists (e.g., 5-15 twists). This is achieved by designing the binding apparatus to automatically limit the twisting operation, thereby reducing binding time while maintaining sufficient binding strength through optimized twist counts.
2Loss of time
If the wire is twisted a predetermined number of times to minimize binding time, then the binding time is reduced, but the binding tension becomes inconsistent
Solution Approach 1:
The patent introduces dynamic adjustment capability to the binding apparatus, allowing the predetermined number of twists to be adjusted based on specific binding requirements. The apparatus can adaptively modify twisting parameters during operation to maintain consistent binding tension across different binding positions and object configurations, resolving the inconsistency problem while preserving quick binding times.
3Strength
If excessive tension is applied to the wire to ensure tight binding, then the binding tightness is improved, but the wire may rupture
Solution Approach 1:
The patent applies the principle of partial action by limiting the wire twisting to a predetermined number of times rather than continuing until maximum tension is reached. This controlled partial twisting achieves sufficient binding tightness without applying excessive tension that would cause wire rupture, thereby improving reliability while maintaining adequate binding strength.
4Adaptability or versatility
If the wire path is adjusted to accommodate varying bar angles and protrusion positions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent designs the binding apparatus with universal adaptability features that allow it to handle various bar angles and protrusion positions without requiring complex adjustment mechanisms. The apparatus is configured to accommodate a range of configurations through its inherent design flexibility, maintaining simplicity while achieving high adaptability to different reinforcing bar arrangements.
