Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single X-ray emission tube is used to generate X-rays, then the device structure is simple, but the heat dissipation requirement is extremely high leading to large volume and weight
Solution Approach 1:
The patent divides the single X-ray emission tube into multiple emission tubes (first, second, third, and fourth tubes). Each tube handles a portion of the total X-ray generation workload, thereby reducing the heat generation burden on each individual tube and enabling a more compact cooling system.
2Device complexity
If a single X-ray emission tube is used to generate X-rays, then the device structure is simple, but the cooling layer must be giant size to dissipate heat
Solution Approach 1:
The patent divides the single X-ray emission tube into multiple emission tubes (first, second, third, and fourth tubes). Each tube handles a portion of the total X-ray generation workload, thereby reducing the heat generation burden on each individual tube and enabling a more compact cooling system.
3Temperature
If multiple X-ray emission tubes are used to generate X-rays, then the heat dissipation requirement is reduced, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple X-ray emission tubes into a single integrated housing structure with a unified cooling layer. The controller integrates the operation of all tubes, switching between them in sequence. This merging approach maintains the heat dissipation benefits of multiple tubes while minimizing structural complexity through integration.
Solution Approach 2:
The controller switches between the multiple X-ray emission tubes in a periodic sequence, activating each tube for a limited duration before switching to the next. This periodic operation allows each tube to cool down between activations, reducing peak heat dissipation requirements while maintaining continuous X-ray output capability.
4Volume of stationary object
If multiple X-ray emission tubes are used to generate X-rays, then the cooling system size is reduced, but the control complexity increases
Solution Approach 1:
The controller switches between the multiple X-ray emission tubes in a periodic sequence, activating each tube for a limited duration before switching to the next. This periodic operation allows each tube to cool down between activations, reducing peak heat dissipation requirements while maintaining continuous X-ray output capability.
Solution Approach 2:
The patent incorporates temperature detection modules that continuously monitor the temperature of each X-ray emission tube. The controller receives this feedback information and adjusts the activation sequence and duration of each tube accordingly, optimizing heat dissipation management while maintaining system reliability.

Function Achieved in This Case
This solution reduces the need for a giant cooling system, decreases manufacturing costs, improves installation ease, and enhances the device's availability and operating efficiency by distributing workload across multiple tubes and dynamically adjusting operational parameters.
Implementation Method 1
a lens module for guiding the plurality of X-rays toward the object to form the integrated X-ray beam
Implementation Method 2
electromagnetic waves will be generated when charged particles are accelerated or decelerated. Therefore, since electrons of the electronic beam BE are rapidly stopped by atoms of the metal anode 110, a part of an energy loss of the electrons during the inelastic collision will be converted into an energy of an X-ray BX
Implementation Method 3
the cooing layer 140 is filled with cooling water or cooling oil to avoid the metal anode 110 from melting
