Solution Overview
Problem
The operability of driving devices with cylindrical magazines housing fasteners in a roll form and electrical motors moving a striking portion is reduced due to inefficiencies in the interaction between the motor, striking mechanism, and magazine alignment.
Innovation Solution
A driving device design featuring a cylindrical magazine for spirally arranging fasteners, a striking portion movable in two directions, a first bias for initial movement, an electrical motor for opposing movement, and a handle with a rotary shaft orthogonal to the striking portion's plane, enhancing the operational efficiency by optimizing the alignment and power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electrical motor is arranged with its rotary shaft extending in the moving direction of the striking portion, then the power transmission is simplified, but the operability and posture control become difficult
Solution Approach 1:
The rotary shaft of the electrical motor is oriented orthogonal to the moving direction of the striking portion, transitioning from a unidimensional power transmission path to a multidimensional arrangement. This spatial reconfiguration allows the motor to be positioned in a location that does not interfere with the striking mechanism's motion path, thereby improving operability and posture control while maintaining effective power transmission through the gear mechanism.
2Productivity
If the magazine is positioned to feed fasteners efficiently, then the feeding speed increases, but the alignment with the electrical motor and striking portion becomes difficult
Solution Approach 1:
The magazine is arranged in a spatial configuration that is orthogonal to the moving direction of the striking portion, allowing independent optimization of feeding speed and alignment. This multidimensional arrangement enables the magazine to be positioned for efficient fastener delivery while maintaining precise alignment with the electrical motor and striking portion through the gear mechanism, resolving the conflict between feeding speed and alignment precision.
3Speed
If the electrical motor is positioned close to the striking portion, then the response speed improves, but the handle operation and magazine access become interfered
Solution Approach 1:
The electrical motor is positioned in a location that is spatially separated from the handle operation area and magazine access path, yet maintains effective power transmission to the striking portion through the gear mechanism. This orthogonal arrangement of the rotary shaft allows the motor to respond quickly to operational commands while the handle and magazine can be accessed and operated without interference from the motor's physical presence.
