Product concept design method for improving user satisfaction based on case-based reasoning.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Product design methods based on case-based reasoning (CBR) generally lack sufficient consideration of customer opinions. To address this problem, a user satisfaction-oriented CBR method for product conceptual design is proposed. The method consists of three stages. First, a quantitative mapping relationship between design cases and user satisfaction is established, and a case base is constructed. Subsequently, new product structural solutions are generated by adopting case reuse or innovative design approaches. Finally, a multi-objective decision-making model incorporating multi-dimensional factors is established to solve for the optimal conceptual design scheme. A conceptual design project for a tablet computer demonstrates that the proposed method effectively enhances user satisfaction with design schemes. This method provides a new perspective for the research of case-based product design methods and is of great value for improving the design symmetry between the conceptual design scheme and user requirements, and thereby enhancing the quality of enterprise product conceptual design.
