Coupled Shutter Plate Structure for Chip-Resistant Machine Tool Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional L-shape intermediate covers in dustproof cover devices have low resistance to external forces from chips, lubricant, and dust, leading to deformation and damage.
Innovation Solution
A shutter device with overlapping shutter plates equipped with a coupling unit that enhances resistance by allowing the plates to expand and contract, preventing deformation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If thinner L-shape intermediate covers are used, then the device complexity is reduced and ease of manufacture is improved, but the resistance to external force from chips, lubricant, and dust is insufficient, causing deformation and damage
Solution Approach 1:
The patent combines multiple intermediate covers into a single integrated intermediate cover structure. This merged cover has improved resistance to external forces from chips, lubricant, and dust compared to multiple thin separate covers, while maintaining ease of manufacture through a unified design that can be produced as a single component.
2Strength
If a single thick intermediate cover is used, then the resistance to external force is improved, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent segments the intermediate cover into multiple functional regions: a horizontal cover portion and a vertical cover portion forming an L-shape. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity and resistance to external forces, without requiring a single complex thick cover design.
3Adaptability or versatility
If thinner shutter plates are used, then the shutter device can expand and contract more easily, but the resistance to external force is reduced, causing deformation and damage
Solution Approach 1:
The patent merges multiple shutter plates into a single intermediate cover structure that maintains the ability to expand and contract with the dustproof cover device. This unified structure provides improved resistance to external forces while preserving the necessary adaptability for expansion and contraction movements.
4Ease of manufacture
If multiple thin intermediate covers are used, then the device can be manufactured more easily, but the resistance to external force is insufficient, causing deformation and damage
Solution Approach 1:
The patent combines multiple thin intermediate covers into a single robust intermediate cover that maintains ease of manufacture through a unified design. This merged structure significantly improves reliability by providing sufficient resistance to deformation and damage from external forces while remaining manufacturable as a single component.

AI summary
Component deformation or damage is prevented. A shutter device which moves in conjunction with momement of a moving unit in a predetermined direction comprises a first shutter which moves in the predetermined direction inconjunction with movement of the moving unit to cover part of an opening and a second shutter arranged between an end of the opening and the first shutter to expand and contract in the predetermined direction in conjunction with momement of the moving unit. The second shutter comprises a plurality of shutter plates overlapping each other, each of which having a first plate whose longitudinal direction is along the predetermined direction and a second plate whose longitudinal direction is along a perpendicular direction to the first plate. The second plate of the shutter plate of the second shutter is provided with a coupling unit which couples the overlapping shutter plates in a manner that they can move in the predetermined direction relative to each other.
