Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing imaging devices can only open their displays up to about 90°, limiting their functionality and requiring complex hinge mechanisms to achieve higher angles, which complicates the design and increases the device's size.

Innovation Solution

An imaging device with a display part that is slidably and turnably connected to the imaging device body through a hinge, allowing the display to be easily turned up to 180° without the need for large hinges or biaxial mechanisms, using a protective part and sliding contact mechanism to facilitate this movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex hinge mechanism or large hinge is incorporated to enable the display to open up to 180°, then the display opening angle is improved, but the device complexity and design are worsened

Engineering Contradiction:

Improvedisplay opening angleVSAvoidhinge mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge mechanism is divided into two functional segments: a rotating section that enables angular movement and a sliding section that enables linear displacement. This segmentation allows the display to achieve 180° opening angle through coordinated rotation and sliding actions rather than requiring a complex single mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A sliding mechanism acts as an intermediary between the rotating hinge and the display panel. This intermediary converts rotational motion into combined rotational-translational motion, enabling the display to open to 180° while maintaining a simple hinge structure that does not compromise design

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If a simple hinge structure is used, then the device complexity is improved, but the display opening angle is worsened (limited to 90°)

Engineering Contradiction:

Improvehinge structure simplicityVSAvoiddisplay opening angle

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The hinge structure transitions from a static 90° limitation to a dynamic system where the display can rotate beyond 90° and simultaneously slide along the base body. This dynamic behavior enables 180° opening while keeping the hinge structure itself simple and maintainable

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the display is made turnable up to 180°, then the self-imaging capability is improved, but the need for large hinges or complex mechanisms worsens the design

Engineering Contradiction:

Improveself-imaging capabilityVSAvoiddevice design integrity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The solution moves from a single rotational dimension to a two-dimensional motion space combining rotation and sliding. This dimensional expansion enables 180° opening for self-imaging functionality while keeping each individual component (hinge and base body) compact and design-friendly

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
