Door Opening Device with Protective Profile and Concealed Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems with protective profiles do not efficiently utilize installation space and can be visually unappealing due to visible hinges and drives.
Innovation Solution
A door system with a protective profile that conceals hinges and incorporates a drive within a cavity, allowing for a visually appealing and space-efficient design, utilizing the protective profile to pivot the door leaf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective profile is added to prevent finger trapping, then safety is improved, but the device complexity increases
Solution Approach 1:
The protective profile is merged with the drive housing to form a single integrated component. This combination eliminates the need for separate protective elements, reducing overall device complexity while maintaining the safety function of preventing finger trapping in the gap between door leaf and door frame.
Solution Approach 2:
The protective profile serves multiple functions: it acts as both a safety device to prevent finger trapping and as a housing structure for the drive mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while improving safety.
2Volume of stationary object
If the drive is placed within the protective profile cavity, then installation space utilization is improved, but the visual appearance may be affected
Solution Approach 1:
The drive housing is merged with the protective profile, creating a unified structure where the drive is concealed within the cavity of the protective profile. This integration maximizes installation space utilization while maintaining a clean, seamless visual appearance from the exterior.
Solution Approach 2:
The drive mechanism is nested within the cavity of the protective profile, similar to a nested doll structure. This nesting arrangement efficiently utilizes the available installation space within the protective profile while keeping the drive hidden from external view, preserving aesthetic appearance.
3Shape
If the protective profile extends beyond the door hinges to conceal them, then visual appearance is improved, but the length of the protective profile increases
Solution Approach 1:
The protective profile is extended to overlap with the door hinges, merging their visual appearance into a unified concealed structure. This extension hides the hinges within the protective profile's length, creating a seamless visual appearance while the increased length is accepted as part of the integrated design.
