Vessel Touch Panel with Separate Activation Operator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel touch panel devices face challenges with erroneous inputs due to water droplets or seawater splashes, requiring operators to manage multiple switches and maintain unstable postures, leading to increased errors and operational burdens.
Innovation Solution
A vessel touch panel device with a separate non-touch panel activation operator that transitions the device between active and inactive states based on predetermined conditions, allowing one-handed operation and automatic state management to prevent erroneous inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel device is used for vessel operation, then operability is improved, but erroneous input from water droplets or seawater splashes increases
Solution Approach 1:
The system activates a preliminary confirmation procedure before executing touch panel inputs. When a touch input is detected, the system checks whether it matches predetermined operation patterns or requires confirmation, thereby preventing erroneous inputs from water droplets while maintaining ease of operation for valid inputs
2Reliability
If an erroneous operation prevention confirmation switch is added, then reliability is improved, but device complexity increases
Solution Approach 1:
The confirmation function is merged with the existing touch panel interface rather than adding separate physical switches. The touch panel itself serves dual purposes: primary operation input and confirmation input, eliminating the need for additional confirmation switches while maintaining reliability
3Reliability
If a physical operation switch is provided separately from the touch panel, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
The touch panel is designed to serve multiple functions: primary operation input, confirmation input, and error prevention. By making the touch panel universal for all input purposes, the system eliminates the need for separate physical operation switches while maintaining input accuracy through software-based validation
4Reliability
If continuous operation of confirmation switch is required, then erroneous operation prevention is improved, but operator burden increases
Solution Approach 1:
Instead of requiring continuous confirmation switch operation, the system uses periodic validation where the touch input is checked against predetermined patterns or conditions. This periodic checking mechanism provides erroneous operation prevention without requiring continuous operator action, thereby reducing burden

AI summary
A vessel touch panel device mounted on a vessel includes a touch panel, a first instruction output that outputs a first instruction when a first operation instruction is input to the touch panel, a second instruction output that outputs a second instruction when a second operation instruction is input to the touch panel, a non-touch panel type activation operator that is provided separately from the touch panel, and a controller. The activation operator is operated by a user in order that a state of the vessel touch panel device is transferred from a first state where the first instruction output is inactive to a second state where the first instruction output is active. The controller performs activation control based on when a predetermined first condition is satisfied when in the first state, and deactivation control when in the second state a predetermined second condition is satisfied.
