Solution Overview

Problem

Existing agricultural binding apparatuses lack the ability to adjust wire tension in real-time as the wire is being pulled around objects, leading to potential damage to delicate vine shoots due to excessive tension or slacking, especially when encountering objects of varying diameters.

Innovation Solution

A hand-held binding apparatus with a tension adjusting mechanism that allows for selective pushing or restraining of the wire, controlled by motors and gears, to maintain tension within a predefined range, ensuring consistent binding performance across different object diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wire is pulled around large diameter or rough objects, then the binding coverage is improved, but the wire tension becomes excessively high causing damage to vine shoots

Engineering Contradiction:
Improvebinding coverageVSAvoidwire damage to vine shoots
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a tension adjusting means that dynamically modifies the wire tension during the binding operation. As the pulling member moves around objects of varying diameters and surface conditions, the tension adjusting means selectively pushes or restrains the wire to maintain tension within a safe range, preventing damage to delicate vine shoots while accommodating large diameter or rough objects.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the physical parameter of wire tension during operation. By using the tension adjusting means to push or restrain the wire, the patent modifies the tension parameter in real-time based on the object being bound, ensuring optimal tension for different binding scenarios without causing damage.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the wire is pushed around objects without tension, then the apparatus can handle various objects, but the wire becomes slack or crumpled making it difficult to reach the terminal

Engineering Contradiction:
Improvehandling capabilityVSAvoidwire guidance to terminal
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The tension adjusting means provides dynamic control of wire tension during the pushing operation. Rather than maintaining constant tension or no tension, the system adaptively adjusts tension levels to ensure the wire remains sufficiently taut to reach the terminal while still being gentle enough not to damage the vine shoot, resolving the contradiction between handling versatility and operational ease.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback through the tension adjusting means which responds to the wire's movement and tension state. This feedback mechanism allows the system to maintain appropriate tension levels that prevent wire slacking while ensuring the wire can be properly guided to the terminal for twisting.

Inventive Principle:
Principle #23Feedback

3Strength

If high wire tension is used to ensure secure binding, then binding strength is improved, but the wire may break when encountering large diameter or rough objects

Engineering Contradiction:
Improvebinding strengthVSAvoidwire breakage risk
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent uses dynamic tension adjustment to maintain binding strength without causing wire breakage. The tension adjusting means continuously adapts the wire tension during the binding operation, providing high tension when needed for secure binding on suitable objects, and reducing tension when encountering large diameter or rough objects that would cause wire breakage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides protective cushioning by anticipating and preventing excessive tension buildup. The tension adjusting means acts as a cushioning mechanism that limits maximum wire tension to below the breakage threshold while still maintaining sufficient tension for effective binding, thereby protecting against wire failure.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
