Design of coffee grinder manual
قبل ما ابدأ في التصميم قمت بدراسة المنتجات الموجودة في السوق , دراسة الية العمل و مميزات و عيوب كل منتج
فقمت بأستخراج 10 عيوب قمت بحلها عن طريق 7 افكار و هي كالأتي:
1- عند تحريك المقبض كان هناك مقاومة في الدوران لذلك لحل تلك المشكلة تم عمل نظام نقل حركة اكثر سلاسة و اقل عدد اجزاء.
2- الفئة المستهدفة من تصميم المنتج هي اصحاب محلات بيع البن لذلك الانتاج الكمي و الدقة و الوقت هما المطلوبان .
3-نتوئات لدغ الطحن ستكون مصنوعة من الخزف 75 mm حيث انها اكثر دقة في الطحن و طويلة العمر و ملائمة للطحن الدقيق و لكن من عيوبها انها هشة اذا وقعت , و لكن تغاضينا عن ذلك حيث ان المطحنة ستكون ثابتة دائما بحكم الفئة المستهدفة
4- نتوئات اللطحن بمقاس 75 mm متواجده في السوق و تحتاج سرعة دوران اقل بسبب الزيادة في مساحة السطح و تهدف للتعامل الانتاجي.
5-بعض العملاء يواجهون مشكلة في فك وعاء التخزين فتم عمل قفل ميكانيكي يصل وعاء التخزين بالجسم العلوي مماثل لقفل الخلاط .
6-مشكلة اليد تكون معرضة للكسر لأنها مرتبطة بالجسم عن طريق صامولة و ايضا الصامولة تتعرض لأحتكاك البري نتيجة فكها و تركيبها بأستمرار كلما اردنا وضع حبوب البن من اعلي فتم حل تلك المشكلة عن طريق عمل اليد مدمجة مع الجسم و تتحرك فيه عن طريق مجري .
7- بعض الاصدارات شكلها الخارجي عبارة عن جسم اسطواني و لم يكن به جزء مطاطي للامساك به حيث كانو يتعرضو لأنزلاق المطحنة فتم عمل تجويف يدخل بمسافة قليلة داخل الجسم لأحكام الامساك .
8- تم مراعاة القواعد الارجنوميكية في التصميم حيث ان ارتفاع المطحنة لا يتجاوز ال 190 mm , عرضها عبارة عن 80 mm , طول اليد 170 mm و وزن المطحنة في حدود 550 gram
Before I started designing, I studied the products on the market, the working mechanism and the advantages and disadvantages of each product
So I extracted 10 defects that I solved using 7 ideas, which are as follows:
1- When moving the handle, there was resistance in rotation, so to solve this problem, a smoother transmission system with fewer parts was created.
2- The target group for product design is the owners of coffee shops, so quantitative production, accuracy, and time are what are required.
3- The grinding burr burrs will be made of 75 mm ceramic, as they are more accurate in grinding, long-lasting, and suitable for fine grinding, but one of their disadvantages is that they are fragile if they fall, but we overlooked that, as the grinder will always be stable due to the target group.
4- Grinding burrs with a size of 75 mm are available on the market and require a lower rotation speed due to the increase in surface area and are intended for production processing.
5- Some customers face a problem in dismantling the storage container, so a mechanical lock was created that connects the storage container to the upper body, similar to the mixer lock.
6- The problem of the hand is that it is vulnerable to breakage because it is connected to the body via a nut, and the nut is also exposed to wild friction as a result of its constant dismantling and installation whenever we want to place the coffee beans from above, so this problem was solved by making the hand integrated with the body and moving within it via a duct.
7- Some versions had a cylindrical body in external shape and did not have a rubber part to grip it, as they were subject to the grinder slipping, so a cavity was made that entered a small distance inside the body to ensure grip.
8- Ergonomic rules were taken into account in the design, as the height of the grinder does not exceed 190 mm, its width is 80 mm, the length of the handle is 170 mm, and the weight of the grinder is about 550 grams.
