Adjustable Grip Binding Machine Reducing Wiring Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines require complex internal wiring and length adjustments, leading to reduced electrical efficiency and increased operational burdens due to the need for telescopic parts and potential wiring malfunctions during assembly and use.
Innovation Solution
A binding machine design that allows for adjustable grip positions without extending the connecting part, using grips that can be positioned along the axis of the twisting shaft to accommodate operators of varying heights and situations, thereby simplifying length adjustments and reducing wiring complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a telescopic part is used to adjust the length from the guide part to the handle, then the handle position can be adjusted for operators of different heights, but the internal wiring becomes complicated and electrical efficiency decreases
Solution Approach 1:
The invention divides the adjusting mechanism into two independent segments: the connecting part length remains fixed to maintain simple wiring, while the grip position on the handle is segmented into multiple adjustable positions. This allows handle position adjustment without extending the connecting part, thus avoiding wiring complexity.
Solution Approach 2:
Instead of adjusting the length of the connecting part (one-dimensional adjustment), the invention shifts the adjustment to the grip position along the handle (another dimension). The grip can be positioned at different locations on the handle body, providing adaptability without changing the connecting part length.
2Adaptability or versatility
If the connecting part length is extended to adjust the entire length of the binding machine, then the machine can accommodate different operator heights, but the electrical efficiency is lowered due to extended electric wire length
Solution Approach 1:
The invention separates the adjustment function from the connecting part and assigns it to the grip position on the handle. This segmentation ensures that the connecting part length remains constant, preventing electrical efficiency loss, while the grip position provides the necessary adjustability.
Solution Approach 2:
The invention creates multiple grip positions on the handle as alternative options, allowing operators to choose the most comfortable position without physically extending the machine. This is similar to having multiple copies of the grip at different locations.
3Adaptability or versatility
If the connecting part is detached and reassembled to adjust the entire length, then the machine can be adapted to different situations, but the operation becomes troublesome and wiring malfunctions may occur
Solution Approach 1:
The invention makes the grip position dynamic and adjustable without requiring detachment of the connecting part. The grip can be easily repositioned along the handle while the connecting part remains firmly connected, ensuring both adaptability and operational ease.
Solution Approach 2:
The invention extracts the adjustment function from the connecting part assembly/detachment process and relocates it to the grip position on the handle. This extraction eliminates the need for troublesome reassembly operations and potential wiring malfunctions.
4Device complexity
If the grip position is fixed, then the machine structure is simple, but operators must lean forward causing high burden on the waist
Solution Approach 1:
The invention introduces dynamic adjustability to the grip position on the handle, allowing operators to choose positions that maintain a comfortable posture. This dynamic feature improves operator comfort while maintaining relatively simple machine structure.
Solution Approach 2:
The invention changes the parameter of grip position from fixed to variable, allowing operators to adjust the position according to their height and comfort needs. This parameter change improves ease of operation without significantly complicating the machine structure.

AI summary
A rebar binding machine comprises a curl guide that causes a wire to curl, a torsion part including a torsion shaft for twisting the curled wire, and a pair of grips that can be grasped by an operator. The grips are provided to the two axial sides of the torsion shaft as viewed from the operator side when the operator grasps the grips to perform an operation, and it is possible to change the height of the grips in the axial direction of the torsion shaft.
