Problem
Existing mounting plates for door operators face challenges in compensating for tolerances during assembly, leading to expensive and time-consuming installation processes, especially in the context of cost pressure in the door closer industry.
Innovation Solution
A mounting plate design featuring multiple fastening areas, a mounting area with threaded holes, and compensating elements such as slots and eccentrics, allowing for adjustable alignment and displacement relative to the door, enabling flexible and quick assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional mounting plates with fixed through holes are used, then the structure is simple and manufacturing is easy, but tolerances during mounting cannot be compensated leading to complex and time-consuming installation
Solution Approach 1:
The mounting plate transitions from a static fixed-hole structure to a dynamic adjustable structure where the mounting area can be shifted relative to the fastening areas using compensating elements like slots and eccentrics, enabling real-time alignment adjustments during installation to compensate for tolerances
Solution Approach 2:
The mounting plate is divided into functionally independent components: fastening areas for attachment to the door and a separate mounting area for the door operator, connected through compensating elements that allow relative movement between these segments to accommodate tolerance variations
2Device complexity
If mounting plates without tolerance compensation are used, then the structure is simpler, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The mounting plate incorporates dynamic adjustment capabilities through compensating elements that allow the mounting area to be shifted and aligned during installation, transforming a static structure into one that can adapt to tolerance variations without requiring complex pre-alignment procedures
Solution Approach 2:
The position parameters of the mounting area relative to the fastening areas are made variable through compensating elements like slots and eccentrics, allowing installation personnel to adjust the mounting plate's alignment parameters on-site to compensate for manufacturing tolerances and avoid time-consuming rework
3Adaptability or versatility
If adjustable mounting areas are implemented, then tolerance compensation is enabled, but the device complexity increases
Solution Approach 1:
The mounting plate employs dynamic adjustment mechanisms where the mounting area can be shifted relative to the fastening areas through compensating elements, providing adaptability for tolerance compensation while maintaining a relatively simple overall structure through straightforward mechanical connections
Solution Approach 2:
Compensating elements such as slots and eccentrics serve as intermediary components between the fastening areas and the mounting area, enabling relative movement and alignment adjustment without requiring complex integrated mechanisms, thus providing adaptability with minimal added complexity
