Accessory Mounting Device with Visual Lock State Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory mounting devices for X-ray radiography systems fail to securely recognize and ensure the fixing condition of accessories, particularly when the table is changed from a horizontal to a standing position, leading to potential patient safety issues during examinations.
Innovation Solution
The proposed accessory mounting device includes a fixing member that oscillates to engage with a pin in a concave element on the table, a movement restriction member that can be oscillated to a restriction position, and a lock mechanism to prevent movement, with visual display regions indicating the lock state, ensuring secure fixation of accessories to the table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin and fixing member mechanism is used to mount accessories to the table, then the accessory can be fixed to the table, but the fixing condition cannot be securely recognized or confirmed
Solution Approach 1:
The patent implements a visual feedback mechanism through a display window that shows different patterns (through-hole pattern for locked state, recessed pattern for unlocked state) to indicate the fixing condition of the accessory. This allows operators to visually confirm whether the accessory is properly fixed without complex instrumentation, directly addressing the reliability of fixing condition recognition.
Solution Approach 2:
The patent introduces a display window as an intermediary element that mediates between the internal locking mechanism and the external observer. The display window translates the internal mechanical state (locked/unlocked) into visible visual patterns, enabling secure recognition of the fixing condition without exposing the complex internal mechanism.
2Adaptability or versatility
If the table is changed from horizontal to standing position during examination, then patient positioning flexibility is improved, but accessory fixation security deteriorates
Solution Approach 1:
The patent employs a lock pin that automatically engages with a lock hole when the fixing member is inserted into the concave element. This preliminary locking action occurs before the table position is changed, ensuring the accessory is securely fixed in advance. The visual display window also provides preliminary confirmation of the locked state before position changes occur.
Solution Approach 2:
The movement restriction member and lock mechanism provide preliminary anti-action by preventing unintended movement of the accessory. The lock pin physically blocks the fixing member from moving once engaged, counteracting any forces that might cause the accessory to detach during table position changes.
3Reliability
If a lock mechanism with movement restriction member is added to prevent accessory movement, then fixation security is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components: the display window serves both as a visual indicator and as part of the locking mechanism structure; the lock pin serves both as a locking element and as a visual indicator when engaged; the movement restriction member is integrated with the fixing member assembly. This merging reduces overall device complexity while maintaining improved fixation security.
Solution Approach 2:
The display window performs multiple functions: it indicates the locked/unlocked state through different visual patterns, it provides structural support for the locking mechanism, and it guides the operator during the mounting process. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

AI summary
An accessory mounting device and system for the same, particularly involving radiographic systems, includes a feature to securely recognize a fixing condition of an accessory. In mounting a platform to a table, a fixing member is oscillated or moved so that the platform moves to an engagement position. A pin installed at a tip of the fixing member engages a fixing element formed in the table. Then, a movement restriction member is oscillated so that it can move to a restriction position. An oscillating movement of the movement restriction member is restricted by moving a lock-pin. Alternatively, a fixing member in a movable non-lock-state allows a display region recognizable from a display position.
