Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current millimeter wave three-dimensional holographic scan imaging technologies for human body security inspection are limited by their inability to efficiently scan all sides of an object, particularly in crowded areas, due to the large footprint of cylinder scanning apparatuses which cannot image four sides entirely.
Innovation Solution
A millimeter wave three-dimensional holographic scan imaging apparatus featuring multiple millimeter wave transceiver antenna arrays arranged in a circular ring or semi-circular shapes, with guiding devices and door mechanisms that allow for simultaneous scanning of peripheral sides, reducing the apparatus volume and improving efficiency by enabling objects to enter and exit without turning, and using a rotatable door for compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cylinder scanning imaging technology is used, then the apparatus can perform three-dimensional holographic scanning, but the footprint becomes large and cannot image four sides entirely
Solution Approach 1:
The patent divides the scanning system into multiple independent millimeter wave transceiver antenna arrays, each responsible for scanning a specific side of the object. These segmented arrays can be arranged in a compact configuration to cover all four sides of the object, resolving the contradiction between comprehensive scanning coverage and large apparatus footprint.
Solution Approach 2:
The patent transitions from traditional two-dimensional scanning to three-dimensional holographic scanning by adding depth information through multiple antenna arrays positioned at different spatial locations. This dimensional enhancement enables complete four-side imaging while maintaining a compact apparatus design through optimized spatial arrangement.
2Productivity
If multiple antenna arrays are used to scan all sides, then scanning efficiency improves, but device complexity increases
Solution Approach 1:
The patent combines multiple millimeter wave transceiver antenna arrays into a single integrated apparatus with unified control and processing systems. The arrays are merged into a coordinated system where data from all arrays is processed together to generate comprehensive three-dimensional holographic images, improving scanning efficiency while managing device complexity through integration.
Solution Approach 2:
Each millimeter wave transceiver antenna array is designed with multi-functionality, capable of both transmitting and receiving signals, and each array can scan different sides of the object. This universal design reduces the need for separate specialized components, thereby improving scanning efficiency without proportionally increasing device complexity.
3Area of stationary object
If the apparatus is designed to be compact, then footprint is reduced, but safety may be compromised by exposing antenna arrays
Solution Approach 1:
The patent implements a nested structure where the millimeter wave transceiver antenna arrays are housed within protective enclosures or door mechanisms. The arrays can be retracted or shielded when not in use, and only exposed during active scanning. This nesting approach maintains a compact apparatus volume while ensuring safety by preventing unnecessary exposure of the antenna arrays.
