Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional independent parts with cables and pipes are used, then each component can be manufactured separately, but the device occupies large space and has high complexity
Solution Approach 1:
The patent integrates the high voltage generator, X-ray tube, and cooling unit into a single integrated housing structure. The high voltage generator is disposed within the housing that also contains the X-ray tube, and the cooling unit is coupled to the housing to provide cooling. This merging eliminates numerous cables and pipes connecting separate components, reducing device complexity while maintaining ease of manufacture through modular integration.
2Area of stationary object
If fan-type X-ray beams are emitted, then the coverage area is large, but the beams cannot be adjusted and require complicated adjustment mechanisms
Solution Approach 1:
The patent incorporates a collimator assembly with collimator leaves that can be adjusted to dynamically control the X-ray beam shape and direction. The collimator leaves are movable and can be positioned to restrict or shape the fan-type beams as needed, providing adjustable beam coverage area and direction without requiring complex external adjustment mechanisms.
3Temperature
If circulating oil cooling or circulating water cooling is used, then heat dissipation effectiveness is high, but the system is susceptible to leakage and inconvenient in application
Solution Approach 1:
The patent replaces the circulating fluid cooling system (oil or water) with a solid-state heat dissipation system. The cooling unit includes a heat sink with heat dissipation fins and a cooling fan that forces air flow over the fins. This mechanical substitution eliminates the need for circulating fluids, removing leakage risks while maintaining effective heat dissipation through forced convection air cooling.
4Ease of manufacture
If multiple independent components are used, then each component can be optimized independently, but miniaturization cannot be achieved
Solution Approach 1:
The patent employs a nested arrangement where the high voltage generator is disposed within the housing that also contains the X-ray tube, and the collimator assembly is integrated within the housing structure. The cooling unit is coupled to the housing and provides cooling to the nested components. This nesting allows each component to be optimized independently while achieving compact miniaturization through space-efficient arrangement.
