Blender Lid Composite Material Design for Appearance and Ease of Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blenders have lids that are often separate parts, requiring users to fully open them to add food or a mixing rod, which can be inconvenient and may not provide a secure grip, and the materials used can appear crude and rough, lacking durability and aesthetic appeal.
Innovation Solution
A blender design featuring a container lid with a removably mounted cap and exterior material made of stainless steel, which covers the lid casing and provides a smooth, rust-resistant surface, allowing for easy insertion of food or tools without opening the lid and enhancing usability and appearance.
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 body made of plastic or resin material, and a lid exterior material made of stainless steel or other aesthetically pleasing material. These two materials are combined through coupling methods such as adhesive coupling, press fitting, or riveting, allowing the lid to achieve both ease of manufacture and high appearance quality simultaneously.
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 divided into multiple functional segments: the lid body, the removable cap, and the lid exterior material. The cap can be selectively removed from the lid body to allow insertion of food or mixing rod, while the lid body remains coupled to the container body for sealing. This segmentation allows the lid to maintain structural simplicity while enabling easy insertion operations without forcing the entire lid open.
3Reliability
If the lid is coupled to a gasket for sealing, then the sealing performance is improved, but the user must forcibly open the lid to access the container body
Solution Approach 1:
The lid system is segmented into the lid body (coupled to gasket for sealing), the removable cap, and the container body. The cap can be independently removed from the lid body without disturbing the gasket-sealed connection between the lid body and container body. This allows users to access the container contents through the cap opening while maintaining the sealed integrity of the overall lid-container assembly.
4Shape
If the lid exterior material is coupled to the lid body by adhesive, then the appearance quality is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The lid exterior material is coupled to the lid body through adhesive bonding, creating a composite structure that combines the aesthetic qualities of stainless steel or other premium materials with the manufacturing advantages of plastic or resin. While adhesive coupling adds some manufacturing complexity compared to single-material construction, it enables the lid to achieve high appearance quality and durability that would be difficult to obtain with single-material construction alone.

AI summary
A blender having an exterior material is provided on an outer surface of a container lid. The blender includes a container body to receive food; a blender body provided at a lower side of the container body and supporting the container body; and a container lid mounted removably to an upper surface of the container body and opening and closing the upper surface of the container body, where the container lid includes a lid casing having a gasket provided at a lower portion thereof; and a lid exterior material covering at least one surface of the lid casing. The lower part of the lid exterior material extends up to an upper part of the gasket, and the lower end of the lid exterior material is bent inward.
