Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray fluoroscopic imaging apparatuses face challenges with a large number of memory switches required for storing multiple rotation positions, leading to operational difficulties due to limited space on the operation board and the need for smaller, yet operable, memory switches.
Innovation Solution
The apparatus incorporates a support mechanism with orthogonal rotation axes, a rotation position detection element, and a memory system where each memory switch stores multiple rotation positions, allowing for intuitive display and selection of rotation positions, reducing the number of physical switches and enhancing auto-positioning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of memory switches is increased to store more rotation positions, then the storage capacity is improved, but the operation board space is exceeded and operability deteriorates
Solution Approach 1:
Each memory switch is designed to store multiple rotation positions (first through fourth positions) simultaneously, making the memory switch multi-functional. This allows a limited number of physical switches to handle a large number of rotation positions, resolving the contradiction between storage capacity and operability
Solution Approach 2:
The patent introduces a temporal dimension to memory switch operation by enabling sequential selection of multiple rotation positions stored in each switch. This transforms the spatial limitation (number of physical switches) into a time-based solution where multiple positions are accessed sequentially from each switch, effectively increasing storage capacity without adding physical switches
2Area of stationary object
If the size of memory switches is reduced to fit more on the operation board, then the space utilization is improved, but the operability of switches deteriorates
Solution Approach 1:
Each memory switch handles multiple rotation positions (up to four positions), reducing the total number of switches needed. This allows sufficient spacing between fewer, larger switches on the operation board, maintaining both space efficiency and operability
Solution Approach 2:
The patent adds a sequential selection mechanism that allows operators to access multiple rotation positions from each switch over time. This temporal dimension reduces the need for numerous small switches, allowing larger, more operable switches to be used while still providing comprehensive rotation position control
3Quantity of substance
If the number of memory switches is increased to store rotation positions for multiple subjects, then the storage capacity is improved, but the device complexity increases
Solution Approach 1:
Each memory switch is designed to store and manage multiple rotation positions (first through fourth positions) universally, regardless of which subject is being examined. This universal design reduces the total number of switches needed across multiple subjects, decreasing device complexity while maintaining high storage capacity
Solution Approach 2:
The sequential selection mechanism allows the same set of memory switches to serve multiple subjects by accessing different stored positions at different times. This temporal reuse of switches eliminates the need for separate switch sets for each subject, significantly reducing device complexity while maintaining the ability to store positions for many subjects
