Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a battery-powered automatic wrench with internal motor and display is designed, then automation and control capability are improved, but device complexity increases
Solution Approach 1:
The patent integrates the battery compartment, motor, and display into the handle structure, nesting multiple functional components within a single housing. The battery storage compartment is disposed within the handle, and the motor is positioned to drive the gear and spindle mechanism, creating a compact nested arrangement that automates wrench operation while managing complexity through integrated design.
Solution Approach 2:
The handle serves multiple functions: it houses the battery storage compartment, contains the motor, displays operational information, and provides structural support. This multi-functionality reduces the need for separate components, thereby improving automation capability without proportionally increasing overall device complexity.
2Ease of operation
If a detachable wrench head design is implemented, then ease of storage and assembly are improved, but device complexity increases
Solution Approach 1:
The wrench is divided into separable components: a handle assembly and a wrench head assembly. The handle can be detached from the wrench head, allowing independent storage and handling of each component. This segmentation improves ease of storage and assembly while the connection mechanism maintains structural integrity during use.
3Power
If transmission system with gear and spindle is added, then mechanical advantage and control are improved, but device complexity increases
Solution Approach 1:
The gear and spindle assembly acts as an intermediary mechanism between the motor and the wrench head. The motor drives the gear, which rotates the spindle, thereby transmitting mechanical advantage to the wrench head. This intermediary transmission system provides controlled mechanical advantage while keeping the motor separate from the wrench head, managing complexity through functional intermediation.

AI summary
A battery powered automatic wrench including a wrench assembly, an electric assembly, and a transmission assembly. The wrench assembly includes a handle that is removably attached to a wrench head. The electrical assembly includes a motor that can be regulated using a display and buttons disposed on the handle. A user can select a predetermined speed and torque for the motor to deliver it. The electrical assembly further includes a battery to power the motor and the display. The transmission assembly includes gears, spindles, a coupler, and toothed belt to transmit motion from the motor to a driving element partially housed by the wrench head. The driving element can receive different sized sockets that are suitable to fasten or loosen nuts, bolts, or the like.
