Personal Blender Clamping Mechanism for Threadless Vessel Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal blenders require threaded vessels for engagement with the blending hub, which can be inconvenient and may not provide a secure sealing mechanism, limiting the ease of use and efficiency in blending.
Innovation Solution
A personal blender design featuring a smooth vessel rim with a clamping mechanism using reciprocating jaws and a seal to engage the vessel, allowing for secure attachment without threads, and a motorized base for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded vessel rim is used for engagement with the blending hub, then the vessel can be securely attached to the hub, but the device complexity increases and ease of operation deteriorates due to threading requirements
Solution Approach 1:
The invention removes the threaded engagement mechanism from the vessel rim, extracting the complexity of threading from the user interface. Instead, a smooth rim is used in combination with a clamping mechanism on the hub that uses elastic jaws to grip the vessel, eliminating the need for users to thread or unscrew components.
Solution Approach 2:
The invention introduces an intermediary clamping mechanism with elastic jaws that mediate between the hub and the smooth vessel rim. This intermediary component provides the secure attachment function without requiring direct threaded engagement between the vessel and hub, thereby simplifying the user interaction.
2Reliability
If a threaded engagement mechanism is used, then the vessel can be firmly secured to the hub, but the device complexity increases
Solution Approach 1:
The threaded engagement mechanism is extracted from the vessel and relocated entirely to the hub as a clamping mechanism. This separates the complexity from the disposable vessel component and concentrates it in the reusable hub, simplifying overall device assembly and manufacturing.
Solution Approach 2:
The clamping mechanism with elastic jaws provides self-aligning and self-adjusting engagement with the smooth vessel rim. The elastic jaws automatically conform to the rim geometry and provide secure grip without requiring precise threading alignment, making the system more tolerant of manufacturing variations.
3Ease of operation
If a smooth vessel rim without threads is used, then the ease of operation improves and device complexity decreases, but the reliability of secure attachment may deteriorate
Solution Approach 1:
The clamping mechanism employs composite construction with elastic jaws made from flexible material that can deform to grip the smooth rim. This combination of rigid structural components and flexible gripping elements provides both ease of operation and reliable attachment.
Solution Approach 2:
The elastic jaws are pre-loaded with clamping force through the spring mechanism, so that when the vessel is placed on the hub, the secure attachment is immediately established without requiring additional user actions. The preliminary elastic deformation of the jaws ensures firm grip from the moment of engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, threadless engagement of the blending vessel with the hub, enhancing user convenience and blending efficiency while minimizing fluid pressure on the seals, allowing for effective blending and easy cleaning.
Implementation Method 1
The hub has a seal adapted to engage in an interior surface of the vessel and a clamping mechanism for engaging an exterior of a rim of the vessel. The vessel rim may be compressed against the seal.
Implementation Method 2
The hub has a pair of opposing reciprocating jaws, the jaws move in unison and are driven toward or away from the vessel. The jaws may be bias radially outward.
