Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If alarm triggering devices use accumulators or batteries for independent operation, then mobility and independence from power supply network are improved, but operating time without battery replacement or recharging is limited
Solution Approach 1:
The patent implements periodic action through the solar charging system that continuously recharges the accumulator during daytime, enabling the device to operate indefinitely without manual intervention. The system periodically converts solar energy to electrical energy to maintain battery charge levels, resolving the contradiction between independence and operating duration.
Solution Approach 2:
The solar-powered alarm system applies self-service by automatically charging its own power source (accumulator) through photovoltaic panels. The device serves itself by converting solar energy directly at the installation location, eliminating the need for external power supply networks or manual battery replacement, thus achieving both independence and unlimited operating time.
2Adaptability or versatility
If alarm solutions use mobile network radio modems with rechargeable batteries, then communication capability is improved, but energy consumption increases requiring frequent recharging
Solution Approach 1:
The system uses periodic action by leveraging daytime solar energy to recharge the battery, enabling continuous operation of the energy-consuming radio modem without frequent manual recharging. The solar panel periodically replenishes energy during daylight hours, offsetting the continuous energy consumption of the communication module.
Solution Approach 2:
The patent applies parameter changes by transitioning from grid-powered or manually recharged systems to a solar-powered system with fundamentally different energy availability parameters. The solar accumulator system changes the energy supply parameter from limited capacity requiring frequent replacement to continuous regeneration, enabling sustained high-energy consumption operations.
3Reliability
If microphones and speakers are operated with higher power levels for reliable voice communication in noisy environments, then communication reliability is improved, but operating time without recharging decreases
Solution Approach 1:
The solar-powered system applies parameter changes by fundamentally altering the energy availability parameter. The continuous solar charging enables the microphones and speakers to operate at higher power levels indefinitely, transforming the trade-off between power level and operating duration into a scenario where both can be maximized simultaneously through unlimited energy supply.
