Electronic Device Peripheral Projection Prevents Erroneous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face issues with erroneous operation and damage due to self-weight when placed on a flat surface, as operation buttons on the sides come into contact with the surface, leading to accidental presses and potential damage to the display.
Innovation Solution
The design incorporates a box-shaped casing with a peripheral projection on the front edge that is taller than the operating units, creating a gap between the device and the surface when placed on a flat surface, preventing accidental operation and protecting the display. Additionally, bowed portions and recessed surfaces enhance grip and prevent shifting, ensuring reliable handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operation buttons are disposed on both sides of the device to increase functionality, then the device can be operated from multiple orientations, but erroneous operation occurs when the device is placed on a flat surface due to self-weight pressing the buttons
Solution Approach 1:
The patent introduces a height dimension by providing a peripheral projection that extends upward from the front surface of the device. This projection creates a vertical barrier that prevents the operation buttons from contacting the flat surface when the device is placed down, thereby eliminating erroneous operation while preserving multi-orientation operability
2Volume of moving object
If the device is miniaturized to meet size requirements, then portability is improved, but space for disposing operation buttons becomes insufficient
Solution Approach 1:
The peripheral projection utilizes the vertical height dimension to create a protective barrier without consuming additional horizontal space. This allows the device to maintain a compact footprint while incorporating features that prevent erroneous operation
3Ease of operation
If operation buttons are placed on the front side for easy access, then ease of operation is improved, but the display unit becomes vulnerable to damage when the device is placed on a flat surface
Solution Approach 1:
The peripheral projection extends in the height direction to create a protective barrier that prevents the display unit from contacting the flat surface, thereby preventing damage while maintaining front-side button accessibility
Solution Approach 2:
The peripheral projection acts as a preventive protective structure that is already in place before the device is placed on a surface, preventing potential damage to the display unit in advance

AI summary
An electronic device of the present invention is an electronic device including a box-shaped casing, a liquid crystal monitor 2 that is disposed on a front face 1a of the casing and on which visual information converted from an information signal can be displayed, and operation buttons 3 disposed near the liquid crystal monitor 2. A peripheral projection 11 projecting in the direction perpendicular to the front face 1a is provided on a peripheral edge portion of the front face 1a. The height of the peripheral projection 11 in the perpendicular direction is formed so as to be greater than the height of the operation buttons 3 with respect to the front face 1a. With this configuration, erroneous operation of the operating portion caused by the self-weight of the device can be prevented.
