A TRIZ-Integrated Conceptual Design Process of a Smart Lawnmower for Uneven Grassland

Existing smart lawnmowers, while convenient to use, have significant limitations, such as a lack of manoeuvrability on uneven agricultural grassland (constraint 1), high charging frequency 2) and low local market penetration 3). Although the effectiveness theory inventive problem solving (TRIZ) has been demonstrated in several design studies, there also seems be research addressing difficulties lawnmowers using this method. With use TRIZ method, study seeks conceptually lawnmower for grassland. Tools from were used, including cause-effect chain analysis, technical contradictions, physical substance field modelling. In developing concept, constraints solved by principles, separation strategies standard solutions. For constraint 1, following solutions chosen with appropriate principles: larger wheels (#17, another dimension: second or third dimension), pivot (#30, flexible shell: replacing rigidity flexibility movability) motor one that more power torque. 2, chosen: reduce weight, add holes mower housing (#31, porous materials: making an object adding elements) attach solar panel recharge batteries energy (#28, mechanical substitution: electric, magnetic other fields interact object). Using materials technologies minimise costs (#13, way around: opposite way) modular concept maintenance (#1, segmentation: dividing into independent parts) ways solve 3. Conceptualisation analysis performed. is unclear, these suggestions are supported previous could potentially some problems lawnmowers.
