Movable Motor Strapping Tool for Operator Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strapping tools are heavy and unbalanced, leading to operator fatigue and reduced efficiency during prolonged use.
Innovation Solution
A strapping tool design featuring a motor housed within the tool's housing, which drives a drive gear engaged with a driven gear. The driven gear is connected to a tensioning assembly that tensions the strap using a pivotable tension wheel, allowing the motor to move relative to the housing and maintain engagement with the driven gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor is fixed within the housing, then the structural simplicity is maintained, but the tool becomes heavy and unbalanced causing operator fatigue
Solution Approach 1:
The motor is made movable relative to the housing through a motor mounting mechanism that allows the motor to move dynamically. This dynamic configuration enables the motor to shift position to achieve better weight distribution and balance, reducing operator fatigue while maintaining structural feasibility.
2Ease of operation
If the tensioning assembly is made pivotable to enable strap removal, then the ease of operation is improved, but the motor must be made movable to maintain gear engagement
Solution Approach 1:
The motor mounting mechanism enables the motor to move dynamically in response to tensioning assembly movements. When the tensioning assembly pivots for strap removal, the motor moves accordingly to maintain proper engagement between the drive gear and driven gear, ensuring continuous operational capability.
Solution Approach 2:
The motor mounting mechanism acts as an intermediary between the fixed housing and the movable motor. It mediates the relationship between the stationary housing structure and the motor that must move to maintain gear engagement, providing a flexible connection that accommodates both requirements.
3Reliability
If the motor is made movable to maintain gear engagement, then the reliability of power transmission is maintained, but the device complexity increases
Solution Approach 1:
The motor mounting mechanism provides dynamic adjustment capability that maintains reliable gear engagement between the drive gear and driven gear. As the motor moves to accommodate tensioning assembly pivoting, the mechanism ensures continuous proper engagement, preventing power transmission failures.
Solution Approach 2:
The motor mounting mechanism is designed to automatically adjust the motor position to maintain proper gear engagement. The system self-regulates to keep the drive gear and driven gear properly engaged without requiring external intervention or complex control systems.

AI summary
The present disclosure provides a strapping tool with a motor that is housed within a housing of the strapping tool and that drives a drive gear that is drivingly engaged with a driven gear. The driven gear is operably connected to a tensioning assembly to drive a tension wheel of the tensioning assembly to tension strap sandwiched between the tension wheel and a tension plate on a support of the strapping wheel. The tensioning assembly is pivotably mounted to the support to enable the operator to pivot the tension wheel away from the tension plate to make room for the strap (or remove the strap). The motor is movable relative to the housing and the tensioning assembly such that, as the tensioning assembly pivots relative to the support, the motor moves relative to the housing and the tensioning assembly so the drive gear maintains driving engagement with the driven gear.
