Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shutter open-closing systems for preventing fire spread have complex operating mechanisms, making manufacturing, assembly, and maintenance difficult, leading to increased operational costs.
Innovation Solution
A simplified shutter open-closing apparatus with a main body connected to a main door, a guide unit, a link unit, and a shutter, where the shutter is driven by the main door's driving force, eliminating the need for separate shutter driving units, and utilizing elastic units for restoring forces to facilitate easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate shutter driving units are used for each shutter member, then the shutter can be driven independently, but the operating mechanism becomes complicated and manufacturing/maintenance difficulty increases
Solution Approach 1:
The patent combines multiple shutter driving units into a single integrated driving unit that controls both shutter members. This merging approach reduces the overall complexity of the operating mechanism while maintaining the ability to control shutter movement, directly resolving the contradiction between independent operation capability and structural complexity.
Solution Approach 2:
The single driving unit is designed to perform multiple functions by controlling both shutter members through a unified mechanism. This multi-functional design eliminates the need for separate dedicated driving units for each shutter, reducing complexity while preserving operational independence through control logic rather than mechanical separation.
2Ease of operation
If separate shutter driving units with power sources are used, then each shutter can be driven independently, but manufacturing and assembly difficulty increases
Solution Approach 1:
The patent merges multiple power sources and driving mechanisms into a single integrated driving unit. This consolidation reduces the number of separate components that need to be manufactured and assembled, directly addressing the manufacturing and assembly difficulty while maintaining independent shutter control through a unified system.
Solution Approach 2:
The driving unit is segmented into functional modules that can be independently manufactured and then assembled into a complete system. This modular segmentation allows for easier manufacturing of individual components while simplifying the overall assembly process compared to integrating multiple separate driving units.
3Ease of operation
If separate shutter driving units are used, then shutter operation is independent, but maintenance difficulty and operating cost increase
Solution Approach 1:
The patent combines multiple driving units into a single maintenanceable component. This merging reduces the number of separate parts that can fail and require maintenance, directly addressing the maintenance difficulty and operating cost issue while preserving independent shutter functionality through control mechanisms rather than mechanical separation.
