Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging apparatuses require motor-driven adjustment of the X-ray incidence surface direction, which lacks manual adjustability in case of motor failure or emergency situations.
Innovation Solution
An X-ray detecting device with a support mechanism for pivotable detector housing, a drive mechanism for rectilinear motion, a switching mechanism for connection/disconnection, a brake mechanism for motion inhibition, and a brake operating means for manual angle adjustment, allowing both motor-driven and manual control of the X-ray incidence surface direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If motor-driven adjustment is used for the X-ray incidence surface direction, then automation and precision are improved, but reliability deteriorates due to motor failure risk
Solution Approach 1:
The system dynamically switches between motor-driven mode and manual mode based on operational needs. The detector housing can be adjusted automatically by the motor drive mechanism during normal operation, and manually when the motor fails or during emergencies, providing adaptive functionality that resolves the contradiction between automation and reliability.
Solution Approach 2:
The system changes the operational parameter from purely automated motor control to a hybrid state where manual intervention is possible. By allowing the operator to manually position the detector housing when needed, the system transforms from a single-mode automated system to a flexible multi-mode system, improving reliability while maintaining automation benefits.
2Manufacturing precision
If motor-driven adjustment is used for the X-ray incidence surface direction, then adjustment precision is improved, but ease of operation deteriorates due to loss of manual control
Solution Approach 1:
The system allows dynamic switching between motor-driven precise adjustment and direct manual control. During normal operation, the motor provides precise positioning. When rapid adjustment or emergency repositioning is needed, the operator can manually move the detector housing without restriction, maintaining ease of operation while preserving precision capabilities.
Solution Approach 2:
The adjustment mechanism serves multiple functions: it provides automated precision adjustment through the motor drive during normal operation, and manual adjustment capability during emergencies or when rapid repositioning is needed. This multi-functionality resolves the contradiction by making the system adaptable to different operational requirements.
3Reliability
If the detector housing is made fully manually adjustable, then ease of operation and reliability are improved, but adjustment precision deteriorates
Solution Approach 1:
The system dynamically adapts its adjustment mode based on requirements. For precise positioning during normal imaging operations, the motor-driven mechanism provides accurate control. For emergency situations or routine repositioning where extreme precision is not critical, manual adjustment is permitted, maintaining reliability and ease of operation without sacrificing necessary precision when needed.
4Reliability
If manual adjustment mechanism is added to the motor-driven system, then reliability and versatility are improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is designed to serve multiple purposes: motor-driven control for precision work and manual operation for emergencies or rapid repositioning. By integrating both capabilities into a single unified system rather than separate systems, the patent avoids excessive complexity while achieving improved reliability and versatility.
Solution Approach 2:
The motor-driven adjustment mechanism and manual adjustment capability are merged into a single integrated system. The manual adjustment features are incorporated into the existing motorized structure, allowing both modes of operation to work together within one unified mechanism, thereby minimizing the increase in device complexity while achieving the desired reliability improvements.
