Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sealing section is designed with a fixed inclination angle and spacing, then the device structure is simple and easy to manufacture, but the adaptability to different installation conditions is poor
Solution Approach 1:
The sealing plate's connection holding section is designed to be bendable, transforming the rigid fixed-angle structure into a dynamic adjustable structure. This allows the inclination angle and spacing of the sealing section to be modified according to different installation conditions without changing the overall device structure, thereby improving adaptability while maintaining structural simplicity.
Solution Approach 2:
The invention enables change of geometric parameters (inclination angle and spacing) of the sealing section by bending the connection holding section. This parameter adjustment capability allows the same device to adapt to various installation conditions, resolving the contradiction between fixed structure and adaptability.
2Reliability
If different sealing devices are prepared for slightly changing installation conditions, then the sealing performance is optimized for each condition, but the production efficiency decreases and cost increases
Solution Approach 1:
The sealing device is designed with adjustable connection holding sections that can be bent to different angles, enabling a single device type to serve multiple installation conditions. This multi-functionality eliminates the need to produce multiple specialized sealing devices, thereby improving production efficiency while maintaining optimal sealing performance for each application.
Solution Approach 2:
The bendable connection holding section provides dynamic adjustability, allowing the sealing device to be customized for different installation conditions after manufacturing. This reduces the need for producing multiple device variants, improving productivity while ensuring reliable sealing performance.
3Adaptability or versatility
If the sealing plates are disassembled and reassembled to change the space configuration, then the adaptability is improved, but the operation complexity and time consumption increase significantly
Solution Approach 1:
The connection holding section is designed as a bendable structure that allows direct angular adjustment without disassembly. This dynamic adjustment capability enables configuration changes while maintaining ease of operation, as users can simply bend the connection section to the desired angle rather than disassembling and reassembling multiple plates.
Solution Approach 2:
The sealing plate is segmented into distinct functional sections (sealing section and connection holding section), with the connection section specifically designed for bending. This segmentation allows independent adjustment of the connection section without affecting the sealing section, simplifying the adjustment operation while maintaining configuration adaptability.

AI summary
The present invention provides a leaf seal device which is available to assemble easily and to control and to set an inclination angle and a space of a sealing section. In the leaf seal device of the present invention, a connection holding section 21 of a sealing plate 12 is bent at a first bending section 22. Thereby, since laminated a plurality of sealing plates 12 are engaged sequentially at the first bending section 22, a radial direction is defined so as to become easily assemble. Also, according to inclining a face 24 at an inner circumferential side of the connection holding section 21, a pitch and a space of a sealing section 31 are changed. Therefore, the space of the sealing section can be controlled, if controlling a bend angle of the first bending section 22.
