Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform spring specifications are used in winding structures, then manufacturing is simplified, but power mismatch occurs for roller blinds of different sizes
Solution Approach 1:
The elastic module is divided into multiple identical sub-modules that can be independently assembled. Each sub-module contains a spring, and multiple sub-modules are connected in series to form the complete elastic module. This segmentation allows the total elastic force to be adjusted by changing the number of sub-modules, thereby resolving the contradiction between manufacturing simplicity (using identical standardized sub-modules) and adaptability (adjusting total elastic force for different blind sizes).
Solution Approach 2:
The elastic force parameter is made adjustable by allowing users to select different numbers of elastic module sub-modules based on the specific application requirements. The patent specifies that the elastic force can be adjusted in steps by adding or removing sub-modules, enabling the same standardized component design to adapt to different roller blind sizes and weights, thus resolving the power mismatch problem while maintaining manufacturing simplicity.
2Ease of manufacture
If spring specifications are determined before installation, then manufacturing is standardized, but secondary adjustment after installation becomes impossible
Solution Approach 1:
The winding structure transitions from a fixed spring specification to a dynamically adjustable configuration. The elastic module sub-modules are designed to be easily addable or removable through a standardized connection interface, allowing the system to adapt its elastic force after installation. This dynamic adjustability resolves the contradiction between manufacturing standardization and post-installation flexibility.
Solution Approach 2:
By segmenting the elastic module into independent, interchangeable sub-modules with standardized connection interfaces (fixing blocks and clamping grooves), the patent enables easy post-installation adjustment. Users can add or remove sub-modules to adjust the total elastic force according to actual usage conditions, while the standardized design maintains manufacturing simplicity.
3Device complexity
If a single spring is used, then the structure is simple, but the range of elastic force adjustment is limited
Solution Approach 1:
Multiple identical elastic module sub-modules are merged in series to form a complete elastic module. Each sub-module contains a spring, and they are connected through fixing blocks and clamping grooves. This merging approach maintains structural simplicity (using repeated identical units) while expanding the adjustment range (by varying the number of combined sub-modules), thereby resolving the contradiction between structural simplicity and adaptability range.
