Radiographing Apparatus Variable-Gap Structure for Drop Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographing apparatuses are susceptible to damage and improper protection when dropped, leading to potential breakage of protruding portions or engaging members and loss of fitting, which compromises the apparatus's integrity.
Innovation Solution
The radiographing apparatus incorporates a support base with a base side protruding portion and a housing with a housing side protruding portion, featuring different gap distances in a perpendicular direction to mitigate stress concentration and prevent fitting release, using a configuration with varying gap sizes and an optional intermediate member for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radiographing apparatus is made highly portable to enable fast and wide-ranged imaging, then the imaging apparatus becomes more portable and easier to handle, but the apparatus becomes more susceptible to damage when dropped
Solution Approach 1:
The patent applies beforehand cushioning by designing a protruding portion on the support base that extends toward the bottom surface, which acts as a protective structure before impact occurs. This protruding portion is configured to contact the housing during impact, absorbing shock and preventing damage to the radiation detector and other sensitive components, thus resolving the contradiction between portability and damage resistance
2Stability of the object's composition
If protruding portions or engaging members are used to restrain movement and provide shock resistance, then the structural stability is improved, but the protruding portions or engaging members may be broken when impact is applied
Solution Approach 1:
The patent applies local quality by creating a protruding portion on the support base with specific geometric characteristics (width, height, thickness) optimized for impact absorption. The protruding portion has a larger width at the bottom end and tapers toward the top, concentrating impact forces in a controlled manner. This localized structural enhancement provides both stability and impact resistance without requiring the entire apparatus to be overly robust
3Loss of energy
If the housing or support base is largely deformed during impact, then the impact energy is absorbed, but the fitting between protruding portions and recessed portions is released
Solution Approach 1:
The patent applies preliminary action by designing the protruding portion on the support base to be positioned in advance toward the bottom surface, ready to engage with the housing before impact occurs. The protruding portion is configured with specific dimensions and positioning so that during impact, it automatically engages with the housing to maintain fitting integrity while still allowing controlled deformation to absorb impact energy

AI summary
A radiographing apparatus includes a support base and a housing. The support base includes a base side protruding portion that protrudes towards a bottom surface of the housing. The housing includes a housing side protruding portion that protrudes in a direction toward the support base. A first gap and a second gap are formed between the base side protruding portion and the housing side protruding portion in a perpendicular direction with respect to an incident direction of radiation at different positions. The first gap and the second gap are different from each other in distance in the perpendicular direction between the base side protruding portion and the housing side protruding portion.
