Blender Lid Composite Material Design for Appearance and Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blenders require users to open the lid completely to insert food or a mixing rod, and the lid design often appears crude and lacks a smooth, high-quality appearance.
Innovation Solution
A blender design featuring a removable cap on the container lid that functions as a handle and allows food or mixing rods to be inserted without opening the lid, with a stainless steel exterior part providing a sleek appearance and preventing sharp edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lid is made of a single material such as plastic or the same material as the container body, then the manufacturing process is simple, but the appearance looks crude and rough
Solution Approach 1:
The lid is constructed using composite materials: a lid casing made of plastic and a lid exterior part made of stainless steel material. The stainless steel lid exterior part is coupled to the plastic lid casing, combining the manufacturing advantages of plastic with the aesthetic advantages of stainless steel to achieve both ease of manufacture and high-quality appearance.
2Device complexity
If the lid is configured as a separate part, then the structure is simple, but the user must forcibly open the lid to insert additional food or mixing rod
Solution Approach 1:
The lid is segmented into functionally independent parts: a lid casing, a removable cap that can be opened independently, and a lid exterior part. This segmentation allows the cap to be opened for inserting food or mixing rod without requiring the user to forcibly open the entire lid structure, maintaining structural simplicity while improving ease of operation.
3Strength
If the center of the upper surface of the lid has a dome shape protruding slightly, then the structural integrity is maintained, but it is difficult for users to hold the lid with their hand
Solution Approach 1:
Different parts of the lid have different surface qualities optimized for their specific functions. The lid exterior part has a smooth surface for aesthetic appearance, while the cap protruding from the center provides a gripping surface for easy handling. This local differentiation of surface properties allows the lid to maintain structural integrity while being easy to hold.
4Ease of operation
If a removable cap is added to the lid, then food can be inserted without opening the lid, but the device complexity increases
Solution Approach 1:
The cap is integrated with the lid structure through coupling relationships rather than being a completely separate component. The lid exterior part is coupled to the lid casing, and the cap protrudes from the lid structure, creating a unified assembly that provides the food insertion function while minimizing the increase in device complexity.

AI summary
A blender having an exterior material provided on the outer surface of a container lid (400) is proposed. The blender includes: a container body (100) configured to receive food; a blender body (500) provided at a lower side of the container body (100) and supporting the container body (100); and a container lid (400) mounted removably to an upper surface of the container body (100) and opening and closing the upper surface of the container body (100), wherein the container lid (400) includes: a lid casing (420) having a gasket (402) provided at a lower portion thereof; and a lid exterior material (430) covering at least one surface of the lid casing (420). The lower part of the lid exterior material (430) extends up to an upper part of the gasket (402), and the lower end of the lid exterior material (430) is bent inward.
