Double Drive Assembly With Integrated Pivoting Levers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor double drives for adjusting support parts of furniture, such as box spring mattresses, are complex and require separate adjustment fittings, making them difficult to assemble and maintain, and lack a simple tool-free assembly mechanism.
Innovation Solution
The electric motor double drive features a base body with permanently attached pivoting levers and a tool-free assembly design, where the pivoting levers are mounted pivotably on the base body, eliminating the need for separate adjustment fittings and allowing for easy assembly and disassembly without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate adjustment fittings are used to connect the drive to the pivoting elements, then the drive can adjust support parts, but the assembly and maintenance become complex and require tools
Solution Approach 1:
The pivoting levers are permanently attached to the base body of the double drive, merging the adjustment fitting function into the drive unit itself. This eliminates separate adjustment fittings and reduces the number of components that need to be assembled and maintained, directly addressing the complexity issue while preserving the adjustment functionality.
2Ease of repair
If traditional linkage levers and spindle nuts are used, then the pivoting mechanism functions, but the assembly requires tools and is difficult to maintain
Solution Approach 1:
By integrating the pivoting levers permanently onto the base body, the invention reduces the number of separate components that can fail or require maintenance. The merged structure eliminates the need for separate adjustment fittings, making the system easier to maintain while preserving all necessary functions.
3Productivity
If multiple separate components are used for adjustment, then the functionality is complete, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The permanent attachment of pivoting levers to the base body reduces the number of assembly steps by eliminating the need to install separate adjustment fittings. This integration directly reduces assembly time and increases productivity while maintaining complete adjustment functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the assembly and maintenance of the double drive, providing a more straightforward and efficient mechanism for adjusting support parts, enhancing usability and reducing the complexity of the assembly process.
Implementation Method 1
Each drive unit has an electric motor, whose drive shaft is connected in a rotary drive connection to a threaded spindle
Implementation Method 2
a threaded spindle (58), on which a spindle nut (56) is arranged, secured against rotation and linearly movable in the axial direction of the threaded spindle (58)
Implementation Method 3
A pressure piece (64) is placed on the end of the threaded spindle (58) facing the pivot axis (28), and the free end of the pivoting lever (26) facing away from the pivot axis (28) carries rollers (30, 30')
