Ship Propulsion Remote Control With Rotatable Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for ship propulsion face challenges in visibility due to external light reflection and varying installation angles, which affect the viewability of the display screen depending on the operator's position and the inclination of the installation surface.
Innovation Solution
A remote control device with a rotatable display unit that can adjust its angle relative to the main body case, allowing the display to be oriented optimally for the operator's viewing, regardless of external light conditions or installation surface inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display screen is fixed at a specific angle relative to the housing, then the device structure is simple and manufacturing is easy, but the display visibility deteriorates under varying external light conditions and installation surface inclinations
Solution Approach 1:
The display unit is made rotatable relative to the housing around an axis extending in the left-right direction, allowing the screen angle to be dynamically adjusted. This dynamic configuration enables the display to adapt to different external light conditions and installation surface inclinations, resolving the contradiction between structural simplicity and display visibility.
2Device complexity
If the display screen angle is fixed to be parallel to the upper surface of the housing, then the device structure is simple, but the display becomes difficult to view when the installation surface is inclined or when external light reflects onto the screen
Solution Approach 1:
The display unit can rotate around an axis extending in the left-right direction, transforming the fixed-angle display into a dynamically adjustable one. This allows the screen to be reoriented to avoid reflection from external light sources and to maintain optimal viewing angles regardless of installation surface inclination, thereby reducing device complexity while improving visibility.
3Ease of operation
If the display angle is fixed, then the device is easy to operate and install, but the display visibility deteriorates depending on the operator's position and external light conditions
Solution Approach 1:
The rotatable display unit allows the operator to adjust the screen angle to an optimal viewing position, maintaining ease of operation while eliminating visibility issues caused by fixed angles. The rotation mechanism enables quick adaptation to different operating conditions without complicating the overall device operation.
