Radiation Detection Panel Support with Hollow Concave Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation detection devices face challenges in reducing weight while maintaining rigidity and preventing damage to the radiation detection panel, particularly due to heavy reinforcing materials and low adhesion issues with foamed core members.
Innovation Solution
A radiation detection device with a supporting member featuring concave portions on its surface, filled with a foamed material filler, and made of lightweight materials like magnesium alloys or fiber-reinforced resins, which increases rigidity and reduces weight by dispersing load through a buffer member and enhancing adhesion, thus preventing positional deviation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing plate made of aluminum alloy is fixed to the base to increase rigidity, then the rigidity of the base is improved, but the weight of the radiography apparatus increases
Solution Approach 1:
The patent applies porous materials by forming hollow concave portions within the supporting member structure. These hollow spaces reduce the overall weight of the supporting member while the surrounding wall structure maintains necessary rigidity. The concave portions are strategically positioned to optimize the strength-to-weight ratio without requiring additional reinforcing plates.
Solution Approach 2:
The supporting member is constructed as a composite structure combining the hollow concave portions with strategic reinforcement elements. This composite design allows different regions of the supporting member to have optimized properties - hollow sections for weight reduction and reinforced sections for structural integrity - resolving the contradiction between rigidity and weight.
2Weight of stationary object
If a low-density core member made of foamed material is used to reduce weight, then the weight of the supporting member is reduced, but the adhesion between components deteriorates
Solution Approach 1:
The patent removes the problematic foamed core member entirely and replaces it with a hollow structure formed by concave portions in the supporting member walls. This extraction eliminates the adhesion problem associated with foamed materials while maintaining the weight reduction benefit through the hollow design.
Solution Approach 2:
The supporting member utilizes thin wall structures forming hollow concave portions that provide structural integrity without requiring heavy reinforcement or low-adhesion foamed materials. The thin film-like walls maintain strength while enabling weight reduction through the hollow configuration.
3Stability of the object's composition
If a convex portion is added to the rear surface of the supporting member to prevent positional deviation, then the positional stability is improved, but the weight of the supporting member increases
Solution Approach 1:
The patent shifts from adding material in one dimension (convex portion protruding outward) to creating spatial efficiency in three dimensions by forming concave portions within the existing structure. The hollow concave portions provide structural optimization and weight reduction while the overall supporting member geometry maintains positional stability through its integration with the housing.
