Solution Overview
Problem
Conventional blenders with separate lids are cumbersome for inserting food or mixing rods, as they require opening the entire lid, and the removable cap designs often expose protrusions to damage and lack a durable, high-quality appearance.
Innovation Solution
A blender design featuring a removable cap with a locking mechanism that includes a locking protrusion on the lid body and a locking passage in the cap, allowing for cap attachment and detachment without opening the lid, along with a lid exterior material for durability and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate lid is used in conventional blenders, then the container is well-sealed, but it is cumbersome to insert food or mixing rods as the entire lid must be opened
Solution Approach 1:
The lid is segmented into two functional parts: a fixed lid body that maintains sealing, and a removable cap that provides access for inserting food or mixing rods. This segmentation allows the sealing function and access function to be independently optimized without requiring the entire lid to be opened.
2Ease of operation
If protrusions are formed on the outer surface of the cap for attachment and detachment, then the cap can be easily removed from the lid body, but the protrusions are exposed to damage or wear from collisions with external objects
Solution Approach 1:
Instead of forming protrusions on the cap that extend outward, the locking protrusions are formed on the lid body and extend inward toward the cap. The cap has corresponding locking passages that receive these protrusions. This inversion protects the protrusions from external damage while maintaining easy attachment and detachment functionality.
3Ease of manufacture
If the lid is made of one material such as plastic or the same material as the container body, then manufacturing is simple, but the lid looks crude and rough to users
Solution Approach 1:
The lid is constructed as a composite structure combining a lid body made of one material (e.g., plastic for durability and ease of manufacture) and a lid exterior material made of another material (e.g., stainless steel for aesthetic appearance). This composite construction allows each material to contribute its superior properties, achieving both manufacturing efficiency and visual appeal.

AI summary
A blender has a removable cap provided in a container lid. The blender includes: a container body configured 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 body having a lid hole vertically formed therethrough; the cap covering the lid hole; and a lock allowing the cap to be removably mounted to the lid body, the lock having a locking protrusion formed by protruding from the lid body to a side thereof, and a locking passage formed in the cap and receiving the locking protrusion.
