Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing devices for shipyards are prone to reduced fixation stability under lateral forces and corrosion, especially in high salt conditions, due to simple structures and inadequate sealing, which can lead to breakage and corrosion of fixtures.
Innovation Solution
A strike assembly type fixing device with a protruding flange formed inclinedly downwardly at the connection portion between the upper and lower ends of the fixture, integrated with a packing ring that enhances compressive force, sealibility, and foreign substance blocking, while simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple fixing device structure is used, then the manufacturing cost is reduced, but the resistance to lateral force deteriorates
Solution Approach 1:
The fixing device is divided into two fixation mechanisms: primary fixation by the lower end inserted into the fixing recess, and secondary fixation by the protruding flange that engages with the fixing plate. This segmentation allows each part to perform its specific function efficiently, improving lateral force resistance without requiring a completely complex structure.
Solution Approach 2:
The protruding flange is formed with a downward inclination at an angle of 45 to 60 degrees, adding a dimensional aspect to the fixation mechanism. This inclined structure converts vertical insertion force into lateral engagement force, enhancing resistance to lateral forces while maintaining manufacturing simplicity.
2Ease of manufacture
If a simple fixing device structure is used, then the manufacturing process is simplified, but the sealibility deteriorates
Solution Approach 1:
A packing ring is introduced as an intermediary sealing element between the fixture and the fixing plate. This packing ring fills the gap created by the protruding flange's downward movement, providing effective sealing against saltwater and foreign substances while maintaining the simplicity of the overall manufacturing process.
3Device complexity
If a simple fixing device structure is used, then the device complexity is reduced, but the resistance to corrosion deteriorates
Solution Approach 1:
The packing ring acts as a flexible sealing element that creates a tight barrier between the fixing plate and the fixture. This flexible seal prevents saltwater and corrosive substances from penetrating into the gap, protecting the fixture from corrosion while maintaining structural simplicity.
Solution Approach 2:
The protruding flange is designed to press down on the packing ring during installation, creating a pre-compressed seal that proactively prevents corrosive substances from entering the fixation interface. This preliminary sealing action occurs before any corrosion can begin, protecting the fixture without requiring complex protective structures.
4Ease of operation
If the lower end of the fixture is inserted into the fixing recess, then the fixation is achieved, but the stability under lateral force deteriorates
Solution Approach 1:
The fixation system is segmented into two independent but complementary mechanisms: the lower end insertion provides primary fixation and ease of installation, while the protruding flange engagement provides secondary fixation and lateral stability. This segmentation allows each mechanism to optimize its function without compromising the other.
Solution Approach 2:
The protruding flange is pre-formed with a downward inclination on the fixture before installation. During the insertion process, this inclined flange automatically engages with the fixing plate, preparing the secondary fixation mechanism in advance to provide immediate lateral stability once the fixture is installed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides improved resistance to lateral forces, enhanced sealing, and increased durability by maximizing the fixing force and airtightness, preventing corrosion and damage from salt penetration, even under high salt and vibration conditions.
Implementation Method 1
a packing ring is provided which is fitted around the lower end of the fixture so as to be brought into close contact with the protruding flange so that the fixture is fixed to the fixing plate by a compressive force by strike
Implementation Method 2
the improvement of sealibility by the packing ring, the excellent foreign substance blocking effect
