Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of attachable and detachable hydrogen tanks are inconvenienced by the uncertainty of how long each hydrogen consuming device can be used when the tank is loaded, as they lack information on the tank's remaining hydrogen amount and its impact on device operation.
Innovation Solution
An information processing apparatus that registers hydrogen consuming devices, acquires hydrogen remaining amounts from these devices, calculates operable device times based on this data, and displays the results, allowing users to know how long each device can be used with a given hydrogen tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users attach and detach hydrogen tanks to multiple hydrogen consuming devices, then the versatility of the hydrogen tank is improved, but the user cannot determine how long each device can be used, worsening the ease of operation
Solution Approach 1:
The hydrogen consuming device transmits hydrogen remaining amount information to the information processing apparatus, which then provides feedback to the user through display. This feedback loop enables users to know the operable duration of each device before attaching the hydrogen tank, resolving the contradiction between versatility and ease of operation
Solution Approach 2:
The system calculates and displays the operable amount of each hydrogen consuming device in advance before the user attaches the hydrogen tank. This preliminary information provision allows users to make informed decisions about which device to use first, improving ease of operation while maintaining versatility
2Duration of action of moving object
If the hydrogen tank stores more hydrogen to extend device usage time, then the duration of action is improved, but the weight and volume of the hydrogen tank increase, worsening the portability
Solution Approach 1:
The system dynamically calculates and displays the operable amount based on the actual hydrogen remaining amount and device consumption characteristics. This allows optimization of hydrogen tank size by providing real-time information about actual usage duration, enabling users to use smaller tanks while knowing the precise operable time
Solution Approach 2:
The information processing apparatus calculates operable amounts by analyzing hydrogen consumption parameters of different devices. This parameter analysis enables determination of minimum required hydrogen quantity to achieve desired operable duration, preventing over-engineering of tank capacity and reducing unnecessary weight
