“…This method is also commonly integrated with other methods, including the TRIZ theory, which systematically analyses problems to come up with innovative solutions [27,28]. Moreover, the development of wireless sensors and intelligent terminals has facilitated various smart services within urban environments [29,30], allowing for more customised requirements [31]. Leveraging the capabilities of ICT devices, this study aims to develop a smart system for urban households based on the AHP-TRIZ method.…”

Food waste management remains a paramount issue in the field of social innovation. While government-led public recycling measures are important, the untapped role of residents in food waste management at the household level also demands attention. This study aims to propose the design of a smart system that leverages sensors, mobile terminals, and cloud data services to facilitate food waste reduction. Unlike conventional solutions that rely on mechanical and biological technologies, the proposed system adopts a user-centric approach. By integrating the analytical hierarchy process and the theory of inventive problem solving, this study delves into users’ actual needs and explores intelligent solutions that are alternatives to traditional approaches to address conflicts in the problem solving phase. The study identifies five main criteria for user demands and highlights user-preferred subcriteria. It determines two physical conflicts and two technical conflicts and explores corresponding information and communications technology (ICT)-related solutions. The tangible outcomes encompass a semi-automated recycling product, a mobile application, and a data centre, which are all designed to help residents navigate the challenges regarding food waste resource utilisation. This study provides an approach that considers users’ genuine demands, empowering them to actively engage in and become practitioners of household food waste reduction. The findings serve as valuable references for similar smart home management systems, providing insights to guide future developments.

In the 21st century's wave of technological advancement, sensors, as a key component of the Internet of Things (IoT), have significantly propelled the development of smart cities and intelligent transportation systems. However, the high deployment costs of traditional sensors limit their practicality for large-scale applications and maintenance. To address this issue, this study proposes a low-cost, concealed, durable, and highly scalable multifunctional smart cement sensor based on triboelectric nanogenerators (SC-TENG) for constructing an allweather intelligent monitoring system. By embedding differently shaped surface insulating electrodes into the cement and applying superhydrophobic treatment to the cement surface, the SC-TENG can effectively monitor vehicle speed, measure vehicle length, and provide fencing warnings in public places at a low cost. Experimental results indicate that the SC-TENG can operate stably under various environmental conditions, maintaining stable output in ambient temperatures from 0 to 40 °C and relative humidity of 30%−70%, with negligible signal degradation even after approximately 2500 cycles. This research is significantly important for enhancing road safety, improving public security, and reducing energy consumption, providing technical support and solutions for the construction of smart cities.
