Curl Guide Structure for One-Handed Ground Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines require manual lifting of binding targets on the ground, increasing operation time and labor, as they lack a mechanism to securely scoop up targets without using a hand opposite to the machine.
Innovation Solution
Incorporating a curl guide with a tapered protrusion at the tip end to scoop up binding targets, allowing the machine to lift them without manual intervention, and providing a detachable guide part to prevent damage and facilitate easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a binding machine is used to bind targets on the ground, then binding efficiency is improved, but manual lifting of the target is required which increases operation time and labor
Solution Approach 1:
The patent combines the lifting function and binding function into a single integrated operation. The curl guide with tapered protrusion performs both lifting the target from the ground and guiding the wire for binding in one continuous motion, eliminating the separate manual lifting step and reducing total operation time.
Solution Approach 2:
The binding machine is designed to perform the lifting action automatically through its own structure (tapered protrusion on curl guide) without requiring external manual intervention. The machine uses its wire feeding and curling mechanism to simultaneously lift and bind the target, making the system self-sufficient.
2Ease of operation
If a curl guide is used to guide wire around the binding target, then binding function is achieved, but the curl guide may be damaged when binding targets on the ground
Solution Approach 1:
The tapered protrusion is designed to make preliminary contact with the ground and target before the main binding operation. This preliminary action lifts the target clear of the ground, preventing the curl guide from contacting or damaging the ground surface during subsequent binding operations.
Solution Approach 2:
The tapered protrusion acts as an intermediary element between the curl guide and the ground/target. It transfers the lifting force from the wire feeding mechanism to the target, protecting the curl guide from direct contact with the ground while still enabling the binding function.
3Productivity
If manual lifting of the binding target is required, then the binding machine can be used, but one-handed operation is not possible which increases labor burden
Solution Approach 1:
The patent merges the lifting function and binding function into a single integrated operation. The curl guide with tapered protrusion performs both lifting the target from the ground and guiding the wire for binding in one continuous motion, eliminating the separate manual lifting step and reducing total operation time.
Solution Approach 2:
The binding machine is designed to perform the lifting action automatically through its own structure (tapered protrusion on curl guide) without requiring external manual intervention. The machine uses its wire feeding and curling mechanism to simultaneously lift and bind the target, making the system self-sufficient.

AI summary
A binding machine includes a curl guide configured to guide a wire in a loop shape around a binding target and a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target. The curl guide has a tapered protrusion at a tip end-side.
