Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing spring-driven retraction and extension devices for extractor hoods are complex and inefficient, lacking a streamlined approach for both production and operation.
Innovation Solution
A construction kit comprising a spring guide device and guide rail, allowing for the selective production of spring-driven retraction and extension devices, with a spring device that can be tensioned in different states to facilitate smooth movement of the vapor screen between extended and retracted positions, and a damping device for jerk-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate production methods are used for retraction and extension devices, then each device can be optimized for its specific function, but the production process becomes complex and inefficient
Solution Approach 1:
The patent applies universality by designing a single construction kit that can produce both retraction and extension devices using the same guide rail, spring guide device, and spring device components. The system achieves functional differentiation not through separate production methods but through configurable assembly of universal components, where the spring device can be tensioned in different states to create either retraction or extension functionality.
2Productivity
If a construction kit with universal components is used, then production is simplified and efficiency increases, but the ability to optimize each device for its specific function is reduced
Solution Approach 1:
The patent applies segmentation by dividing the system into modular components (guide rail, spring guide device, spring device, damping device) that can be independently manufactured and then assembled. This segmentation allows each component to be optimized for its specific function while still being part of a universal construction kit, resolving the contradiction between production efficiency and functional optimization.
Solution Approach 2:
The patent applies dynamics through the configurable tensioning state of the spring device, which can be adjusted during assembly to create either retraction or extension functionality. This dynamic configuration capability allows the universal construction kit to adapt to different functional requirements without requiring separate production processes.
3Adaptability or versatility
If the spring device is tensioned in different states for retraction and extension, then the same construction kit can produce both device types, but the assembly process requires additional configuration steps
Solution Approach 1:
The patent applies preliminary action by pre-configuring the spring device with adjustable tensioning capabilities during the manufacturing stage. The spring device is designed with preliminary configuration features that allow it to be tensioned in different states during assembly, enabling the construction kit to produce both retraction and extension devices without requiring complex post-assembly modifications.
