Engine Test System Visual Feedback for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional internal combustion engine test systems are complex and lack intuitive visualization of operating conditions, making it difficult to prevent operation errors, such as shut-off valve mismanagement and excessive gas feeding, which can lead to equipment damage and safety hazards.
Innovation Solution
An internal combustion engine test system with a system status display that uses symbols to represent test devices on a screen, dynamically changing color, brightness, or pattern based on operating safety conditions, including valve status, gas filling levels, and clogging degrees, to provide immediate visual feedback on operation safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large-scale test system with multiple test devices is adopted to measure both diesel and gasoline engines, then the system becomes compatible for measuring different engine types, but the number of test devices increases and operation errors become more likely
Solution Approach 1:
The patent segments the complex test system into multiple functional modules (exhaust gas sampling system, dilution gas system, measurement equipment, control units). Each module is independently managed with its own control device, allowing the system to handle different engine types while reducing operational complexity through modular organization.
Solution Approach 2:
The patent implements a universal test system architecture that can measure both diesel and gasoline engines using the same hardware platform. The system achieves multi-functionality through configurable measurement parameters and adaptable sampling methods, eliminating the need for separate test systems for different engine types.
2Loss of information
If the operating condition of each test device is displayed as numerical information or character information, then detailed data is provided, but the operating condition of the whole system cannot be recognized at a glance and operation errors are not sufficiently prevented
Solution Approach 1:
The patent uses color-coded visual indicators to represent the operating status of each test device and the overall system. Different colors indicate different operational states (normal, warning, error), allowing operators to instantly recognize system status without interpreting numerical data. This visual feedback system maintains detailed information availability while dramatically improving ease of operation.

AI summary
It is intended to display a schematic diagram of substantially the whole of an internal combustion engine test system on a screen and a color, brightness, pattern or shape of a symbol representing a test device shown in the schematic diagram are changed according to a degree of operation safety of the test device, whereby a user is allowed to intuitively recognize a situation relating to the safety of the entire system at a glance.
