Locking blade base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blender blade bases often become stuck to jar members after use, requiring tools for removal and potentially leading to leaks or detachment during use if not properly secured.
Innovation Solution
A latching member, such as a bale handle, locks the blade base onto the jar member without threads, ensuring secure engagement during blending and easy detachment for cleaning, using a tab and channel mechanism with barbed locking members and a lock-release button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blade base is screwed tightly onto the jar member, then the blender may not leak during use, but the blade base may get stuck to the jar member requiring tools for removal
Solution Approach 1:
The latching member is designed to engage the jar member and blade base in a predetermined sequence, with the barbed locking members first engaging the jar member and then the blade base, ensuring secure attachment before blending while maintaining easy release capability
2Ease of manufacture
If the blade base and jar member are made as separate cleanable parts, then each part can be easily cleaned after use, but the blade base may detach during blending if not properly secured
Solution Approach 1:
The latching mechanism provides localized secure engagement at specific points (jar member and blade base interfaces) while maintaining the overall separability of the components for cleaning purposes

AI summary
A blender is provided that uses a latch handle to lock the blade base onto the jar member without the use of threads. When the latch is locked onto the jar member, the latch itself is engaged to a tab member protruding from the jar member in order to prevent the latch from opening on accident.
