Hand-held Strapper Reversible Motor Module for Ergonomic Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strapping tools, particularly those using pneumatic systems, can be cumbersome and difficult to operate comfortably and efficiently, especially when requiring multiple motor operations for tensioning and welding.
Innovation Solution
A single reversible air or gas driven motor module assembly with adjustable weld time and ergonomic switch placement allows for easy hand operation, featuring a motor module with a grip that includes an opening switch, tensioning switch, and welding switch, along with a weld switch lockout assembly to prevent improper sequencing, and a mechanism to adjust tension and weld time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple pneumatic motors are used for tensioning and welding operations, then the strapping tool achieves reliable and effective performance, but the tool becomes cumbersome and difficult to operate comfortably by hand
Solution Approach 1:
The patent combines multiple pneumatic motors into a single integrated motor module assembly that performs both tensioning and welding operations. This consolidation reduces the number of separate components the user must handle, making the tool more comfortable to operate by hand while maintaining reliable performance through the integrated design.
Solution Approach 2:
The single motor module assembly is designed to perform multiple functions (tensioning and welding) through a unified structure. This multi-functional design allows the tool to maintain effective strapping capabilities while reducing overall complexity and improving ease of hand operation compared to separate motor systems.
2Adaptability or versatility
If multiple motor operations are required for tensioning and welding, then the strapping tool achieves complete functionality, but the control interface becomes complex and difficult to operate
Solution Approach 1:
The control interface elements (grip, triggers, switches) are merged into a single integrated control system that manages both tensioning and welding operations. This consolidation simplifies the user interface while maintaining complete strapping functionality through coordinated control of the single motor module assembly.
Solution Approach 2:
The motor module assembly incorporates automatic sequencing and coordination of tensioning and welding operations through integrated control mechanisms. This self-coordinating design reduces the complexity of manual control while ensuring complete functionality is achieved through automated operational sequences.

AI summary
A strapping tool for tensioning and securing a strap on or around an object or load includes a motor, a tensioning assembly coupled to the motor, and a weld plate assembly coupled to the motor. The motor is actuated in a first direction to control the tensioning assembly to tension the strap during a tensioning operation and the motor is actuated in a second direction to control the weld plate assembly to weld the strap to itself during a welding operation.
