Accuracy and beauty, why are there always contradictory ends? With this question in mind, Maiman asked the team to personally use the market kitchen scale for a week, recording every frowning moment and translating it into executable design parameters: the scale surface ≥ 135 × 135mm, the keys moved to the side, the front and back easy-to-clean plate, and the rotary battery compartment. It will take another four months to overcome the plastic texture, sealing process and mass production tolerance, so that a simple structure scale has the experience of not losing high-end products. Since its launch, sales have exceeded 200000 units, verifying this methodology from experience to parameters to mass production.
