Embedded Remote Control Housing for Stable Radiation Irradiators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation irradiation devices face instability in attaching the remote operation unit due to exposed surfaces, leading to potential detachment and unstable attachment.
Innovation Solution
A radiation irradiation device design that accommodates the remote operation unit within a recessed accommodation portion in the device main body, with a recessed inner wall surface facing all surfaces except one, and includes a holding mechanism to secure the unit in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the remote operation unit is attached to the radiation irradiation unit via a partial surface, then the device structure is simplified and easier to assemble, but the attachment stability deteriorates and the remote operation unit may easily come off
Solution Approach 1:
The remote operation unit is nested within the radiation irradiation unit through the accommodation portion, allowing one component to be housed inside another. This provides secure attachment while maintaining ease of assembly through a simple insertion motion into the recessed accommodation portion.
Solution Approach 2:
The accommodation portion extends in the depth direction from the front surface, creating a three-dimensional recessed space rather than a surface-level attachment. This dimensional change allows the remote operation unit to be securely held within the radiation irradiation unit, preventing it from coming off while maintaining easy assembly.
2Ease of operation
If multiple surfaces of the remote operation unit are exposed, then the operation interface is more accessible, but the attachment stability deteriorates and radiation exposure risk increases
Solution Approach 1:
By nesting the remote operation unit within the radiation irradiation unit's accommodation portion, the design secures attachment stability while maintaining operational accessibility through the exposed front surface and side surfaces that remain reachable for user interaction.
Solution Approach 2:
Instead of completely enclosing the remote operation unit, the design exposes necessary operational surfaces (front and side surfaces) while covering others, providing just enough exposure for safe and effective operation while maintaining attachment stability through the recessed accommodation structure.
3Reliability
If the remote operation unit is accommodated in a recessed accommodation portion, then attachment stability and integrated appearance are improved, but the device complexity increases
Solution Approach 1:
The accommodation portion creates a simple recessed space within the radiation irradiation unit housing, allowing the remote operation unit to be nested inside. This provides attachment stability and integrated appearance without requiring complex mechanical fastening systems or additional components.
Solution Approach 2:
The recessed accommodation portion structure allows the remote operation unit to be self-retaining through its geometric fit within the recess, eliminating the need for additional fasteners, clips, or complex retention mechanisms. The structure itself provides the holding function.

AI summary
A radiation irradiation device includes a device main body that is provided with an irradiation window for emitting radiation; a remote operation unit that is capable of remotely operating the device main body and of which an outer peripheral surface is composed of a plurality of surfaces; and an accommodation portion that is provided in the device main body, accommodates the remote operation unit in a form of being embedded in a main body outer peripheral surface, which is an outer peripheral surface of the device main body, and has a recessed inner wall surface facing an entire surface excluding one surface in the outer peripheral surface of the remote operation unit.
