Electric motor double drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double drives for adjustable support devices, such as bed frames, require complex tool-based assembly processes, which are time-consuming and inconvenient.
Innovation Solution
A tool-free, electric motor-driven double drive system designed for simplified assembly on box-spring mattresses or upholstered beds, featuring a base body with fastening means like wing screws and a housing made of plastic, allowing for easy attachment to support devices without tools, and utilizing linearly movable spindle nuts or threaded spindles for force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional tool-based assembly methods are used for double drives, then reliable fastening is achieved, but assembly time and complexity increase
Solution Approach 1:
The double drive is designed with integrated fastening means that enable self-service assembly without requiring external tools. The housing includes built-in fastening elements that can be operated directly by hand, allowing the device to assemble itself without needing screwdrivers, wrenches, or other tooling equipment.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support, contains internal components, and incorporates integrated fastening means for attachment to the support device. This multi-functionality eliminates the need for separate fastening components and tools.
2Ease of operation
If integrated fastening means are incorporated into the housing, then tool-free assembly is enabled, but housing complexity increases
Solution Approach 1:
The fastening means are merged directly into the housing structure rather than being separate components. This integration combines the housing and fastening functions into a single unified structure, reducing the total number of parts while enabling tool-free assembly through built-in hand-operated fastening elements.
