Antiknock Valve With Bionic Tortoise Shell Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antiknock valves with large valve cores have low structural strength, slow response speed, and limited ability to resist high-level shock waves, allowing significant shock wave energy to pass through and posing risks to people and equipment.
Innovation Solution
A bionic tortoise shell valve design with intersecting supporters and a reduced valve core weight, enhancing the valve's structural strength and response speed, allowing it to withstand higher peak reflection pressures and close faster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large valve core design is adopted to close the ventilation passage, then the valve can block shock waves, but the weight of the valve core increases and structural strength decreases
Solution Approach 1:
The patent divides the single large valve core into multiple smaller valve cores (at least two) that work together to close the ventilation passage. This segmentation reduces the weight and improves the structural strength of each individual valve core while maintaining the overall blocking capability through their combined action
Solution Approach 2:
The patent combines multiple valve cores into a unified closing mechanism where they work together to seal the ventilation passage. The frame body integrates multiple opening/closing mechanisms that cooperate to achieve effective shock wave blocking
2Reliability
If a large valve core design is adopted, then the valve can block shock waves, but the response speed decreases due to large mass
Solution Approach 1:
By dividing the large valve core into multiple smaller valve cores, the mass of each individual core is reduced. This allows them to respond faster to shock waves and achieve quicker closing speeds while still providing effective blocking when all cores are positioned to seal the passage
Solution Approach 2:
The patent changes the mass parameter of the valve core by using multiple smaller cores instead of one large core. This parameter change directly improves the response speed and closing time while maintaining the blocking function through the combined action of all cores
3Reliability
If a large valve core design is adopted, then the valve can block shock waves, but the opening length increases reducing structural strength
Solution Approach 1:
The patent segments the long opening into multiple shorter openings, each associated with individual valve cores. This reduces the length of each moving component (valve core) and improves structural strength while the combined action of multiple short openings achieves the same overall blocking capability
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 bionic tortoise shell valve design significantly improves the valve's ability to resist shock waves, reducing the time to close the ventilation passage and increasing safety performance by reducing the weight and volume of the valve core, enabling it to withstand higher pressures and enhance anti-explosion capabilities.
Implementation Method 1
When an explosion impact occurs, the shock wave pressure applied to the valve core B2 closes the valve core and blocks the shock wave from entering the protected side of the building or the ventilation system
Implementation Method 2
When the shock wave changes from positive pressure to negative pressure, the valve core moves to the other side, reducing the ventilation passage until the valve core closes the ventilation passage

AI summary
An antiknock valve with both sides resisting a shock wave, and a valve body thereof. The antiknock valve includes a valve core (200) and two valve bodies (A3, A4). The valve body (A3/A4) includes a frame body (101/102), wherein two intersected supporters(2a, 2b/3a) are provided in the frame body (101/102) in a symmetrical manner, the supporters (2a, 2b/3a, 3b) intersect on a ridge-shaped column (2d/3d) and openings(2c1/3c2) are provided at intervals along the direction of the ridge-shaped column (2d/3d). The valve cores (200) are located above the openings (2c1/3c2) and the two valve bodies (A3, A4) are engaged and fixed; and one end of the valve core (200) is rotatably connected on the ridge-shaped column (2d/3d). Since the antiknock valve reduces the weight of the valve core (200), the antiknock capacity is improved, a closing speed is increases, and the antiknock valve is safer.
