Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If lead-acid batteries are used for powering electrical consumers in cable car cabins, then energy storage is achieved, but the service life is short and they require full charging at regular intervals
Solution Approach 1:
The patent changes the chemical and physical parameters of the energy storage device from lead-acid battery technology to double-layer capacitor technology. This parameter change enables fast charging capability while maintaining long service life, as double-layer capacitors can be charged in minutes rather than hours and do not suffer from sulfation issues that limit lead-acid battery lifespan.
Solution Approach 2:
The patent substitutes the electrochemical energy storage mechanism of lead-acid batteries with the electrostatic energy storage mechanism of double-layer capacitors. This substitution replaces the slow chemical reactions in lead-acid batteries with rapid charge/discharge cycles in capacitors, eliminating the need for lengthy full charging periods while extending operational duration.
2Use of energy by moving object
If lead-acid batteries are used in cable car cabins, then energy storage is provided, but the weight is considerable making them unsuitable for continuous operation
Solution Approach 1:
The patent changes the energy storage technology parameters from lead-acid batteries to double-layer capacitors, which have a significantly higher power-to-weight ratio. This parameter change enables the system to provide sufficient energy storage capacity for continuous operation while dramatically reducing the weight of the energy storage device in the cable car cabin.
3Temperature
If lead-acid batteries are used for heating in cable car cabins, then heating is possible while in station, but heating is not guaranteed along the entire transport route
Solution Approach 1:
The patent substitutes the slow electrochemical charging process of lead-acid batteries with the rapid electrostatic charging process of double-layer capacitors. This substitution enables the heating system to be recharged quickly during brief station stops, ensuring heating capability is maintained throughout the entire transport route including periods outside stations where lead-acid batteries would be depleted.
4Adaptability or versatility
If lead-acid batteries operate outside temperature range of -18°C to +30°C, then operation continues, but performance is reduced or battery failure occurs
Solution Approach 1:
The patent substitutes the temperature-sensitive electrochemical reactions of lead-acid batteries with the temperature-resilient electrostatic energy storage of double-layer capacitors. This substitution maintains reliable performance across a broader temperature range, including extreme cold conditions where lead-acid batteries would fail or require extensive thermal protection.
5Use of energy by moving object
If lead-acid batteries are used in cable car cabins with closed windows, then energy storage is provided, but extensive heat protection is required due to internal temperatures up to 70°C
Solution Approach 1:
The patent substitutes the heat-generating lead-acid battery system with a double-layer capacitor system that has superior thermal characteristics. This substitution reduces or eliminates the need for extensive heat protection mechanisms, simplifying the overall system design while maintaining energy storage functionality in the confined space of cable car cabins.
