Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door drive units have inefficiencies due to unused space between components and lack of flexibility in assembly, leading to complex and costly manufacturing processes.
Innovation Solution
A door drive unit with a carrier element featuring multiple recesses to house the electric drive, output, and control device, utilizing fixed axes for shaftless mounting and a compact design, allowing for flexible arrangement and space-saving dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual components are screwed onto a common carrier profile next to each other, then the door drive can be assembled from separate parts, but a large amount of space remains unused and the components cannot be arranged flexibly
Solution Approach 1:
The patent merges multiple separate components (drive motor, gearbox, power supply unit, controller) into a single integrated housing. This consolidation eliminates the unused space that would exist between separately mounted components while maintaining the ability to assemble from separate parts. The housing contains all components in a compact arrangement, achieving both ease of manufacture and space efficiency.
2Ease of manufacture
If individual components are screwed onto a common carrier profile, then the door drive can be assembled from separate parts, but the components cannot be arranged flexibly
Solution Approach 1:
The patent applies segmentation by providing the housing with multiple openings at different locations, each suitable for receiving different components. This allows flexible arrangement of components within the housing while maintaining ease of assembly. The segmented opening design enables components to be positioned optimally for both manufacturing and functional requirements.
3Volume of moving object
If a narrow box-shaped door drive housing is used, then space is saved, but the assembly process becomes complex and shafts are stiffened in the housing
Solution Approach 1:
The patent achieves a compact housing design without increasing assembly complexity by making the housing itself multi-functional. The housing serves as both the structural enclosure and the mounting platform for all components. Multiple openings in the housing provide universal mounting points for different components, allowing the same compact housing structure to accommodate various component arrangements without requiring complex assembly procedures.
