智能清洁设备 LCD 屏幕体验设计

Goal：

Design a unified interaction framework across LCDs—scalable to multiple device models—that clearly communicates device states, modes, feedback, and instructional guidance, while remaining easy to operate through simple physical button controls.

Challenges:

Because users navigate only through physical buttons, the display hierarchy must be clear. In addition, variations in screen size and viewing distance across devices require strict guidelines for information density, content sizing, and visual priority.

Key Results:

• Achieved 100% adoption from engineering teams and delivered Dreame’s first floor washer equipped with an LCD—establishing the screen experience as a key product differentiator that directly contributed to sales growth.
• Established a comprehensive hardware screen design system (hierarchy standards, navigation logic, ergonomic guidelines, etc.), significantly improving cross-device consistency and accelerating subsequent project delivery.

目标：

设计一套LCD、跨多机型通用的交互式屏幕体验体系，让设备的状态、模式、反馈与教学信息清晰呈现，同时确保用户能够通过有限的物理按键轻松完成操作。

挑战：

用户只能依赖物理按键进行导航，因此屏幕层级必须极其清晰；同时不同机型的屏幕尺寸与用户视距各不相同，需要严格规范信息密度、内容大小与呈现优先级。

关键成果：

• 技术团队采纳率达到 100%，成功打造追觅首款搭载 LCD 屏幕的洗地机，使屏幕体验成为核心卖点之一，促进产品销量增长。
• 沉淀硬件屏幕设计规范体系（层级规范、跳转逻辑、人因指南等），显著提升跨机型一致性，加速后续项目落地。

User Interaction Flow:

Example flow: product mode changing and working

Example flow: product Self-cleaning Process

Example flow: Visual Instruction for Error Resolution

03｜Usability Testing

Testing confirmed that the three-layer screen strategy—lightweight running state, process visualization, and guided error resolution—significantly improves user comprehension and confidence.

It also validated the reliability of the readability guidelines across real-world viewing conditions.

测试验证了“轻量运行态、过程可视化、引导式故障态”的三层策略有效提升用户理解速度和使用信心。同时验证了可读性屏幕规范在真实使用场景下的可靠性。

04｜Engineering Collaboration

Hardware Constraints Alignment

与结构、电子、嵌入式团队对齐硬件限制，确保设计可行。

• LCD：亮度 / 对比度 / 刷新率能力评估
• 动效：MCU 性能与内存占用限制
• 真实视距下的可读性验证

Final Review & Handoff

交付完整量产文件，使工程端可实现：

• UI 规格（尺寸、间距、状态机）
• 图标与动效切图
• 显示校准方案（亮度 / 色彩还原）
• 演示视频

05 ｜ Review

Hardware design is always a balance between experience quality, product value, and manufacturing feasibility.

This project made me realize that hardware UX is not a linear process, nor is it about achieving perfect visuals—but about finding the best achievable experience within engineering constraints.

Moving forward, I aim to explore more intelligent and proactive feedback mechanisms that further reduce user effort and improve overall clarity.

在硬件限制下，设计无法完全按照理想路径推进，许多功能都需要在体验、产品卖点与量产可行性之间做取舍。本项目让我意识到：硬件体验的推进并不是线性的，而是一个与结构、电控、嵌入式持续协作、不断验证的过程。

相比追求“完美视觉效果”，真正重要的是在工程边界内找到最优的、可实现的体验方案。 未来，我希望进一步探索通过更智能、更主动的反馈机制，降低用户理解和操作成本，让设备体验不仅“能用”，更“好用且易懂”。
