Spherical Instrument Housing Head for Radiation-Safe Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for orienting instruments in hostile environments, such as radioactive environments, are cumbersome and limited in accessibility, with collimators and detectors being bulky and difficult to position accurately, leading to restricted fields of observation and increased operator exposure to radiation.
Innovation Solution
A partially spherical housing head with a movable second part relative to a first part, allowing rotation around an inclined axis, which enhances the field of observation and action while minimizing equipment size and mass, and incorporating shielding materials for radiation protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional collimators and support masts are used to protect instruments in radioactive environments, then radiation protection is improved, but the equipment becomes heavy and bulky
Solution Approach 1:
The housing head is divided into a first part (fixed to support mast) and a second part (movable), allowing the instrument to be positioned within a compact spherical structure while maintaining radiation protection through the housing design
2Object-affected harmful factors
If traditional collimators with cylindrical shapes and support masts are used, then radiation isolation is improved, but the field of observation is limited
Solution Approach 1:
The housing head adopts a spherical shape instead of the traditional cylindrical form, allowing the instrument to be oriented in multiple directions and expanding the field of observation while maintaining radiation isolation through the housing structure
Solution Approach 2:
The second part of the housing head is made movable relative to the first part, enabling dynamic adjustment of the instrument's orientation and expanding the observable solid angles while maintaining radiation protection
3Object-affected harmful factors
If traditional bulky collimators are used to access confined spaces, then radiation protection is improved, but accessibility to confined spaces deteriorates
Solution Approach 1:
The housing head is segmented into movable parts that can be compacted or adjusted, reducing the overall size and bulk of the equipment to enable access to confined spaces while maintaining radiation protection through the housing design
Solution Approach 2:
The movable second part allows the housing head to be compacted or adjusted to fit through narrow access points, improving accessibility to confined spaces while the housing structure maintains radiation protection
4Measurement precision
If traditional support masts with oriented supports are used, then detector positioning is improved, but device complexity increases
Solution Approach 1:
The movable second part of the housing head provides a simpler mechanism for orienting the detector compared to traditional support masts with complex oriented supports, reducing device complexity while maintaining positioning capability
Solution Approach 2:
The spherical housing head with its movable part provides intuitive multi-directional orientation capability, simplifying the positioning mechanism compared to traditional cylindrical collimators requiring complex support structures

AI summary
A head (5) for housing an instrument comprises a first part (6) and a second part (7) which is movable relative to the first part (6). The first part (6) is configured to be rigidly connected to a support mast (22). The second part (7) comprises an opening (73) which leads outside of the head (5) and into a housing for the instrument. The housing is located inside the head (5).
