Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If additional light detectors are added to increase scanning area, then the scanning range is improved, but the volume and cost of the scanner increase
Solution Approach 1:
The patent applies the dynamics principle by making the detecting unit rotatable around the illuminating unit. Instead of using multiple fixed detectors to cover a larger area, a single detecting unit rotates to scan different areas sequentially, thereby expanding the scanning area without increasing the physical volume of the scanner.
Solution Approach 2:
The detecting unit serves multiple functions by rotating to detect different areas of the object. A single detecting unit performs the work of multiple fixed detectors by changing its position through rotation, achieving multi-functionality without proportionally increasing system volume.
2Area of stationary object
If additional light detectors are added to increase scanning area, then the scanning range is improved, but the cost of the scanner increases
Solution Approach 1:
The patent reduces cost by replacing multiple fixed detectors with a single rotatable detecting unit. The mechanical rotation mechanism is simpler and less expensive than acquiring and installing multiple additional detectors, while achieving the same expanded scanning area.
Solution Approach 2:
The detecting unit is designed to be universal and multi-functional, serving multiple detection positions through rotation. This single unit replaces the need for multiple specialized detectors, reducing overall system cost while maintaining comprehensive scanning capability.
3Device complexity
If fixed light sources and detectors are used, then the device complexity is reduced, but the scanning range and image rebuilding efficacy are limited
Solution Approach 1:
The patent introduces controlled motion (rotation) to the system, transforming it from a static fixed configuration to a dynamic scanning system. This adds adaptability by allowing the detecting unit to access different areas of the object while maintaining relatively simple device architecture.
Solution Approach 2:
The patent adds the temporal dimension to the scanning process through rotation. Instead of having multiple detectors simultaneously covering different spaces, the system uses a single detector moving through time at different positions, expanding the effective scanning volume without proportionally increasing spatial complexity.

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 scanner expands the scanning range, enhances image resolution, and reduces the economic burden by allowing continuous scanning of multiple areas with a simpler and more cost-effective design.
Implementation Method 1

Data Source
AI summary
A rotation type optical tomography scanner is provided, including an illuminating unit disposed on a surface of an object-to-be-detected for emitting incident light to tissues under the surface of the object-to-be-detected; a detecting unit disposed on the object-to-be-detected and rotating around the illuminating unit to receive diffuse light diffused from the tissues under the surface of the object-to-be-detected and generate tissue sensing information; and a positioning unit for generating position information of the rotation type optical tomography scanner. The rotation type optical tomography scanner transmits the sensing information and the position information to a remodel module to rebuild the tissue images under the surface of the object-to-be-detected, thereby expanding the scanning range of the object-to-be-detected.
