Manual Binding Tool Deformation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual binding tools face inefficiencies in applying plastic deformation to tie portions for secure engagement, leading to unstable slip-off prevention due to low force transmission efficiency and potential escape of pushing force during deformation.
Innovation Solution
A manual binding tool with a tie holding portion, a pushing mechanism, and a cutting mechanism, where the pushing mechanism deforms the tie portion and engages it into an engagement hole while the head portion is supported, ensuring stable plastic deformation and secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a machine is used to forcibly punch and deform the band, then the slip-off prevention function is more assured, but the device complexity increases and the pushing force may escape due to inadequate support
Solution Approach 1:
The binding tool utilizes the user's manual pressing action as the driving force, eliminating the need for complex powered punching mechanisms. The tool structure guides and concentrates the user's finger pressure to achieve the required deformation force, making the system self-sufficient without external power sources or complex actuation mechanisms.
Solution Approach 2:
The binding tool acts as an intermediary device between the user's finger and the band. It includes a support surface that receives the band and a pressing surface that applies concentrated force to deform the band end. This intermediary structure ensures proper force transmission and prevents force escape by providing stable support for both the band and the user's finger.
2Productivity
If only the free end of the band is supported during punching, then the apparatus structure is simpler, but the force transmission efficiency is very low and plastic deformation is unstable
Solution Approach 1:
The binding tool provides differentiated support at different locations: the support surface holds the band body while the pressing surface concentrates force on the band end. This localized quality distribution ensures that the supported portion receives adequate support force without requiring complex overall structural changes, thereby improving force transmission efficiency.
3Stability of the object's composition
If the head portion is not supported during deformation, then the apparatus structure is simpler, but the pushing force escapes and plastic deformation cannot be formed stably
Solution Approach 1:
The binding tool is pre-configured with a support surface that receives and stabilizes the band body before the user applies pressing force. This preliminary support action prevents the pushing force from escaping during deformation, ensuring stable plastic deformation without requiring complex active control mechanisms.

Function Achieved in This Case
The tool effectively applies deformation force for secure engagement, enhancing slip-off prevention by ensuring the pushing force is used efficiently and eliminating the escape of deformation force, resulting in a more stable and reliable binding mechanism.
Implementation Method 1
a pressing mechanism h which, in a state where the head portion 5 is supported by the tie holding portion g, pushes and deforms a tie portion 4c located in the head portion 5, and which causes the deformed portion 4b to be engaged into an engagement hole 10

AI summary
A manual binding tool including a mechanism for applying plastic deformation to a tie portion located in a head portion to forcibly cause tie portions to engage with each other. A manual binding tool has a tie holding portion that receives and supports a head portion, a tightening mechanism that pulls a projection tie portion that projects through the head portion, a return preventing mechanism that blocks a return movement of the projection tie portion with respect to the head portion that is supported by the tie holding portion, and a pushing mechanism that, in a state where the head portion is supported by the tie holding portion, pushes and deforms a passed tie portion located in the head portion, and that causes the deformed portion to be engaged into an engagement hole of a root tie portion on which the head portion is previously surroundingly held.
