Elliptical Cylinder Electronic Device Cooling and Media Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as entertainment devices, often have operational panels that do not efficiently manage space for cooling and media insertion, leading to reduced operability and increased risk of media falling during insertion or removal.
Innovation Solution
The electronic device features a main housing in an approximately elliptic cylinder form with a horizontal longitudinal direction, a box-like base portion, and a front board portion positioned below the media insertion port, which secures space for cooling and prevents media from falling by providing a stable surface for media insertion and removal, while also incorporating a cover to prevent dust accumulation and entry through the media insertion port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the main housing is disposed vertically, then the device occupies less horizontal space, but cooling efficiency deteriorates due to insufficient space in the upper portion
Solution Approach 1:
The patent rotates the main housing from a vertical orientation to a horizontal orientation, changing the spatial dimension in which the device occupies space. This dimensional change allows the upper portion of the main housing to provide sufficient space for cooling, while the device still occupies minimal horizontal footprint when placed in an accommodation rack.
2Ease of operation
If the medium insertion port is positioned high, then it is easily accessible, but media may fall directly to the floor when inserted or removed
Solution Approach 1:
The patent introduces a front board portion as an intermediary surface between the medium insertion port and the floor. This front board extends downward from the insertion port area, providing a catching surface that prevents media from falling directly to the floor while maintaining easy accessibility of the port.
3Reliability
If the front board portion area is increased, then media falling is prevented more securely, but device complexity increases
Solution Approach 1:
The patent segments the device structure into distinct functional portions: the main housing, the base portion, and the front board portion. This segmentation allows the front board to be designed as a simple, separate element that provides media catching functionality without complicating the overall device architecture.
4Stability of the object's composition
If the base portion is attached centrally, then structural stability is improved, but cooling efficiency and wiring space deteriorate due to space occupation
Solution Approach 1:
The patent attaches the base portion to the lower portion of the main housing in an asymmetric, offset position rather than centrally. This asymmetric attachment allows the lower portion of the main housing to provide sufficient space for cooling and wiring while the base portion still provides adequate structural support through its offset positioning.

AI summary
An entertainment device or other electronic device having an outward shape improved in functionality compared with that in the related art are provided. The electronic device includes a main housing that is formed in an approximately elliptical cylinder form, and disposed in a such a manner that a longitudinal direction is approximately horizontal to a setting surface, and has medium insertion ports for inserting a portable information storage medium such as an optical disk, and an approximately boxlike base portion attached to a lower portion of the main housing.
