Transmission Dock Drainage Through Pivotal Concave Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices face issues with water ingress leading to potential damage, and additional drainage holes compromise device aesthetics and invite foreign substances.
Innovation Solution
A transmission dock with pivotal concave portions and sloped inner surfaces guides water to openings within the concave portions for discharge, eliminating the need for additional drainage holes on the casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional drainage holes are provided on the casing to discharge water, then water discharge function is improved, but foreign substances are more likely to enter the interior and aesthetic value deteriorates
Solution Approach 1:
The drainage function is merged with the existing pivotal concave portion structure. The concave portion serves dual purposes: as a mechanical feature for pivotal connection and as a water drainage channel. The sloped inner surface of the third wall guides water to the opening at the pivotal concave portion, eliminating the need for separate drainage holes on the casing.
Solution Approach 2:
The pivotal concave portion is given multiple functions: it serves as a mechanical connection point for pivotal movement and simultaneously as a water drainage outlet. The opening at the pivotal concave portion that would otherwise be solely for mechanical purposes now also functions as a drainage aperture, utilizing existing structure for dual purposes.
2Reliability
If additional drainage holes are provided on the casing to discharge water, then water discharge function is improved, but appearance aesthetic value deteriorates
Solution Approach 1:
The drainage function is merged with the existing pivotal concave portion structure. The concave portion serves dual purposes: as a mechanical feature for pivotal connection and as a water drainage channel. The sloped inner surface of the third wall guides water to the opening at the pivotal concave portion, eliminating the need for separate drainage holes on the casing.
Solution Approach 2:
The drainage function is extracted from the casing surface and relocated to the pivotal concave portion. Instead of creating new openings in the casing, the water discharge path is routed through the existing pivotal concave portion opening, removing the aesthetic burden from the casing design.

AI summary
An electronic device includes an input unit and a transmission dock. The transmission dock is pivotally connected to the input unit, and includes at least one pivotal concave portion, a first wall, a second wall and a third wall. The at least one pivotal concave portion has a first sidewall and a second sidewall opposite to each other. The first wall is connected to the first sidewall and the second sidewall. The second wall is connected to the first sidewall and the second sidewall. The third wall is connected to the first sidewall and the second sidewall. The first wall and the second wall are connected to two opposite sides of the third wall, respectively. An inner surface of the third wall forms a sloped surface toward each of the first sidewall and the second sidewall, and each of the sloped surfaces has an opening at an end thereof.
