Winch Symmetry via Segmented Motor Housing and Reel Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winch designs require significant modifications to the motor and reel holder to achieve symmetry, leading to increased manufacturing difficulties, part versatility issues, and higher costs due to the need for new components and wasted productivity.
Innovation Solution
A winch design that connects the control unit to the motor using a housing with an in-and-out power supply structure, featuring a first electrical connection terminal adjacent to the control unit, allowing for direct use of existing motor components with minimal modifications, and a connection structure that simplifies electrical connections and assembly while maintaining symmetry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the motor and first reel holder are significantly redesigned to achieve symmetry, then the winch shape design is facilitated and symmetry is achieved, but manufacturing difficulty increases and original parts cannot be reused
Solution Approach 1:
The patent divides the motor into two separate components: the motor outer shell and the first reel holder. This segmentation allows each component to be manufactured independently using existing processes and parts, avoiding the need for significant redesign while still achieving the desired symmetric appearance when assembled together.
Solution Approach 2:
The first reel holder is designed to serve dual functions: it acts as both a structural component holding the reel and as a closure for the motor housing. This multi-functionality allows it to contribute to the symmetric appearance without requiring separate cosmetic covers, simplifying manufacturing while achieving the aesthetic goal.
2Shape
If the motor and first reel holder are significantly redesigned to achieve symmetry, then the winch shape design is facilitated, but the cost increases due to waste of original productivity
Solution Approach 1:
The first reel holder is designed to serve dual functions: it acts as both a structural component holding the reel and as a closure for the motor housing. This multi-functionality allows it to contribute to the symmetric appearance without requiring separate cosmetic covers, simplifying manufacturing while achieving the aesthetic goal.
Solution Approach 2:
The patent retains and reuses existing motor components and first reel holder designs where possible, rather than discarding them for complete redesign. This approach recovers the value of original productivity investments while still achieving the desired symmetric appearance through strategic assembly and minimal modifications.
3Device complexity
If the control unit is electrically connected to the motor through a bus bar with a cover plate, then the winch shape design is facilitated and simple connection is achieved, but the control unit cannot be used separately and significant modifications are required
Solution Approach 1:
The electrical connection system is segmented into modular components: the control unit with its own terminal, the motor with its terminal, and a detachable bus bar connector. This segmentation allows the control unit to be electrically connected to the motor when needed while also being able to operate independently or with different motors, enhancing versatility while maintaining simple connection capabilities.
4Shape
If the control unit and motor are significantly modified to achieve symmetry, then the winch shape design is facilitated, but manufacturing difficulty and cost increase
Solution Approach 1:
The patent divides the motor into two separate components: the motor outer shell and the first reel holder. This segmentation allows each component to be manufactured independently using existing processes and parts, avoiding the need for significant redesign while still achieving the desired symmetric appearance when assembled together.
