Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual lifting of heavy loads is physically exhausting, inefficient, and leads to strain and injury, necessitating a device that reduces physical effort and integrates with common power tools for enhanced usability and portability.
Innovation Solution
A power-assisted winch device with a rotating drum and ½-inch drive connection for impact drills, automating the lifting process by transferring torque from the drill to the winch drum, featuring a control module for speed regulation and an auto-lock mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If manual chain winch is used to lift heavy loads, then lifting capability is achieved, but physical strain and fatigue increase significantly
Solution Approach 1:
The patent replaces the manual mechanical operation of the winch with a power tool motor. The impact driver or drill motor provides automated rotational force to turn the winch drum, eliminating the need for manual cranking while maintaining the mechanical lifting function. This substitution directly resolves the contradiction by preserving lifting capability while eliminating physical strain.
2Device complexity
If manual operation is used, then device simplicity is maintained, but productivity and efficiency decrease
Solution Approach 1:
The winch device is designed to be compatible with common power tools (impact drivers and drills) through standardized mounting interfaces. This universality allows the winch to leverage the motor power of these tools, dramatically increasing lifting speed and productivity while maintaining operational simplicity through familiar tool interfaces and procedures.
3Speed
If power tool integration is added, then lifting speed increases, but device complexity increases
Solution Approach 1:
The winch device is designed as a modular attachment that segments the lifting function from the power source. The winch unit itself remains relatively simple, while the power tool motor provides the additional complexity of automated power delivery. This segmentation allows high lifting speed without permanently increasing the complexity of the winch mechanism itself.
4Ease of operation
If automated power assistance is implemented, then physical effort is reduced, but device portability may be compromised
Solution Approach 1:
By designing the winch as a universal attachment compatible with existing power tools, the system avoids adding a dedicated motor to the winch unit. This approach reduces the weight of the moving winch device itself, as the motor weight is borne by the already-owned power tool, thereby maintaining portability while achieving power-assisted operation.
