Electronic Device Stand Ventilation and Support Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with stands lack an efficient configuration that allows for improved support and ventilation, particularly when the stand is in a closed state.
Innovation Solution
The electronic device features a housing with a transition wall that includes a recessed part and a ventilation hole, and a stand that can move between closed and open states, covering part of the recessed part when closed to provide support and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the stand is configured to cover the recessed part when closed, then the external appearance is improved and support stability is enhanced, but ventilation effectiveness may be reduced
Solution Approach 1:
The recessed part is divided into multiple ventilation holes distributed across its surface. When the stand is closed, it covers the recessed part but cannot completely block all ventilation holes, allowing air to pass through multiple small openings while maintaining a sleek external appearance.
Solution Approach 2:
The stand is designed with specific geometric features (curved bottom end part) that allow it to cover portions of the recessed part selectively. The coverage is localized rather than complete, enabling the stand to improve appearance in certain areas while leaving ventilation pathways open in other areas.
2Strength
If the transition wall extends further to the front, then structural support is improved, but the space for ventilation and recessed part configuration becomes more constrained
Solution Approach 1:
The transition wall extends in the front-back direction (one dimension) to provide structural support, while ventilation holes are created in the vertical and lateral dimensions. This multi-dimensional approach allows the transition wall to achieve structural strength without compromising ventilation space.
Solution Approach 2:
The transition wall incorporates ventilation holes that create a porous structure. This allows the transition wall to maintain structural integrity while providing pathways for air flow, effectively combining strength requirements with ventilation needs.
3Shape
If the stand is made to cover the recessed part completely, then appearance is maximally improved, but ventilation is completely blocked
Solution Approach 1:
The stand covers part of the recessed part but not all of it. This partial coverage approach provides sufficient appearance improvement while deliberately leaving portions of the recessed part exposed to maintain ventilation functionality. The design accepts that complete coverage is unnecessary for achieving the desired aesthetic effect.

AI summary
An electronic device includes: a housing; a display provided at a front side thereof; and a stand provided at a back side thereof. The housing has a transition wall between back and bottom walls, which extends further to the front as further downwardly separated from the back wall. The transition wall has a recessed part and a ventilation hole communicated with the recessed part. The stand is attached to the housing so that the stand can move between a closed state where the stand approaches the back wall and an open state where a bottom end part of the stand is separated away from the back wall so that the stand can support the housing at an angle from a placement surface. The stand is configured so that the bottom end part of the stand covers part of the recessed part when the stand is in the closed state.
