Solution Overview

Problem

Conventional X-ray imaging devices in dental clinics apply excessive pressure to the examinee's head, causing pain due to manual operation and concentration of pressure at the end of the temple supporter's movement.

Innovation Solution

An examinee arranging apparatus with a guide portion that applies pressure through movement, an operating driving portion for controlling movement, an elasticity portion for deformation response, and a switch to stop movement when a reference pressure is reached, preventing excessive force application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used to move the temple supporter, then the examinee arranging apparatus can be operated flexibly, but excessive pressure is applied to the examinee's head causing pain

Engineering Contradiction:
Improvemanual operation flexibilityVSAvoidexcessive pressure on examinee's head
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical operation with an automatic driving mechanism. The temple supporter is moved automatically by a driving unit that controls the movement along the arc shape, eliminating the need for manual operation and preventing excessive pressure application through automated pressure control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent incorporates a pressure detection mechanism that provides feedback on the pressure applied to the examinee's head. This feedback system allows the driving unit to adjust the movement and pressure in real-time, ensuring that pressure remains within comfortable limits while maintaining positioning accuracy.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If the temple supporter moves along an arc shape, then the examinee's head can be positioned correctly, but pressure concentrates at the end of movement causing pain

Engineering Contradiction:
Improvehead positioning accuracyVSAvoidpressure concentration at movement end
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent transforms the static arc-shaped path into a dynamic controlled movement system. The driving unit adjusts the movement speed and pressure distribution along the arc path, slowing down or reducing pressure as the temple supporter approaches the end position, thereby preventing pressure concentration while maintaining positioning precision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a pressure control mechanism that anticipates the pressure concentration issue at the end of the arc movement. By pre-adjusting the driving force and pressure distribution before reaching the end position, the system prevents excessive pressure buildup while ensuring accurate head positioning.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
