Internal Arm Locking Mechanism for Portable Radiation Irradiation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable radiation irradiation devices face challenges in restricting the movement of their arm parts during transport to prevent damage from vibration, while existing solutions often expose locking mechanisms that can become obstacles for users.
Innovation Solution
The device incorporates an arm locking part housed inside the arm part, with an unlocking mechanism that moves parallel to the arm's extension direction, allowing for rotational restriction without external obstructions, and a support member locking part that interlocks with the arm's rotational movement to prevent unwanted rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an arm locking mechanism is provided outside the arm part to restrict movement during transport, then the arm part can be effectively locked, but the locking mechanism becomes an obstacle for users
Solution Approach 1:
The arm locking part is nested inside the arm part, with the locking mechanism housed within the arm part's structure. The locking pin is received in a recess formed in the arm part, and the unlocking mechanism is operated from the outer surface of the arm part without exposing external locking components. This nesting approach resolves the contradiction by providing reliable internal locking while maintaining external accessibility for users.
2Weight of moving object
If the arm part is made lightweight for portability, then the device becomes more mobile, but the arm part becomes more susceptible to vibration damage
Solution Approach 1:
The arm locking part is designed to prevent harmful vibrations from affecting the arm part during transport. By providing a locking mechanism that secures the arm part in a fixed position, the invention applies preliminary anti-action to counteract the harmful effects of vibration before they can cause damage to the lightweight arm part.
3Reliability
If the locking mechanism is made complex to ensure secure locking, then the arm part can be reliably restricted, but the device complexity increases
Solution Approach 1:
The locking and unlocking functions are extracted as separate, simple mechanisms. The arm locking part includes a locking pin that can be inserted or removed to engage or disengage the lock, and an unlocking mechanism that is independently operated. This separation of functions simplifies the overall mechanism while maintaining reliable locking security, avoiding the need for a single complex integrated system.
