Solution Overview
Problem
Existing portable screwdriving tools face usability challenges when dealing with unfavorably arranged screw parts, requiring frequent pivoting and the use of handling devices, which complicates operations and increases manufacturing costs.
Innovation Solution
A portable screwdriving tool with two output devices arranged at an angle greater than 30°, each equipped with a measuring device and a gear system, allowing for independent control and wireless data transmission, enabling versatile operation without the need for constant pivoting and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single output device is used in portable screwdriving tools, then the device complexity is reduced, but the ease of operation deteriorates when dealing with unfavorably arranged screw parts requiring frequent pivoting
Solution Approach 1:
The tool is segmented into two independent output devices (first and second output devices) that can operate independently. Each output device can be selectively activated based on the working requirements, allowing the user to switch between different screwing positions without pivoting the entire tool, thereby improving ease of operation while maintaining manageable device complexity through modular design
Solution Approach 2:
The tool achieves multi-functionality by equipping it with two output devices that can perform screwing operations in different orientations and positions. This universal design allows the same tool to handle various screwing scenarios (different angles and positions) that would otherwise require different specialized tools or frequent pivoting, thus improving ease of operation across diverse applications
2Adaptability or versatility
If two output devices are added to improve versatility, then the adaptability increases, but the manufacturing cost increases due to different components
Solution Approach 1:
The patent applies homogeneity by making the two output devices identical in structure and configuration. Both output devices use the same components, gears, and measuring devices, which standardizes the manufacturing process and reduces production costs. This homogeneous design allows for mass production of identical modules while still providing the versatility of having two independently controllable output devices for different working positions
3Measurement precision
If measuring devices are added to each output device, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
By using identical measuring devices in both output devices, the patent achieves measurement precision for both outputs while simplifying the overall system design. The homogeneous measuring components can be mass-produced and standardized, reducing the complexity of integration and calibration compared to using different types of measuring devices. This approach maintains high measurement precision through consistent, proven technology while controlling device complexity through standardization
