Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray detectors used for industrial pipe inspections face damage to circuit units when bent to match the round outer appearance of pipes, leading to image distortion and component failure.
Innovation Solution
The X-ray detector incorporates flexible circuit units and support boards with a flexible sensor panel, eliminating the need for hard circuit units by transmitting gate control signals through flexible circuit units, allowing the detector to be bent without damaging components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the X-ray detector is bent to match the round outer appearance of the pipe, then the detector can be used for industrial pipe inspections, but the gate circuit units or read out circuit units may be damaged
Solution Approach 1:
The patent replaces hard circuit units with flexible circuit units that can bend without breaking. The flexible circuit units are attached to the sensor panel and can accommodate the bending motion when the detector is shaped to match pipe contours, eliminating the risk of circuit unit damage while maintaining electrical connectivity.
Solution Approach 2:
The patent makes the circuit units dynamic by using flexible materials that can change shape during operation. The flexible circuit units can dynamically adapt their shape as the sensor panel is bent, allowing the detector to transition between flat and curved configurations without compromising circuit integrity.
2Reliability
If hard circuit units are used to drive gate ICs, then the circuit units can provide stable electrical connection, but the detector cannot be bent without risking component damage
Solution Approach 1:
The patent uses flexible circuit units instead of hard circuit units to drive gate ICs. These flexible circuit units maintain stable electrical connections while accommodating bending motions, allowing the detector to be shaped to match pipe appearances without risking component damage.
Solution Approach 2:
The patent changes the physical state of the circuit units from rigid to flexible. This parameter change allows the circuit units to withstand bending stresses while maintaining their electrical connection function, enabling the detector to adapt to curved pipe surfaces.
3Reliability
If the sensor panel is made flexible to avoid damage during bending, then the detector can be bent safely, but the circuit units may still cause image distortion
Solution Approach 1:
The patent segments the detector into modular components: a flexible sensor panel and separate flexible circuit units. This segmentation allows each component to be optimized independently - the sensor panel can be made highly flexible for safe bending, while the circuit units maintain precise electrical connections to prevent image distortion.
Solution Approach 2:
The flexible circuit units act as intermediaries between the flexible sensor panel and the control circuits. These intermediary components transmit signals reliably while accommodating the flexibility of the sensor panel, ensuring that bending does not cause image distortion.
