Product Design: A Kitchen Blender Built for Blind and Low-Vision Cooks

A product manager is asked to design a blender for people who are visually impaired. Explain whom you would design it for, what makes an ordinary blender hard to use without full sight, what you would build, and how you would judge whether the design works. ```hint Walk through one use Mentally run a blender from setup to cleanup without looking. Every step where a sighted person relies on a quick glance is a candidate pain point. ``` ### Clarifying Questions - Is this a home blender for personal use, or a commercial unit for cafes and restaurants? - Should the design cover the full range of vision loss, from total blindness to partial sight, or one part of that range? - Are we an established appliance maker extending a product line or a new company, and is the aim to win this niche or to make a mainstream blender accessible? - May the design rely on a smartphone or smart speaker, or must it work fully on its own? ### What a Strong Answer Covers - Segmentation by both degree of vision loss and blending habits, with a reasoned choice of whom to serve first. - A step-by-step view of blending that surfaces the non-visual pain points: assembly and locking, choosing settings, judging texture, safety around the blades, and cleaning. - Solutions that use touch, sound and voice, including at least one that works without any connected device. - Prioritization with explicit criteria, plus a plan to test the design with blind and low-vision users. - Success metrics with safety guardrails. ### Follow-up Questions - Would you sell it as a specialized assistive product or as a mainstream blender with inclusive design, and how does that choice change pricing and distribution? - How would the design change for a user who is both blind and hard of hearing? - In a pilot, users miss the finish signal because the kitchen is noisy.
