Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blender interlock systems are prone to damage, failure, and inefficiency due to mechanical components that can lead to false actuation and are difficult to clean, and they often require a specific container-base combination, limiting versatility and causing issues like spilled contents or improper functioning.
Innovation Solution
A blender system utilizing Near Field Communication (NFC) components in the container and base to ensure proper interlocking and operation, allowing for wireless communication and power transfer, thus eliminating the need for mechanical connections and enabling compatibility with various container sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical interlock systems are used to prevent blade rotation when lid is removed, then safety is improved, but the system becomes prone to damage and false actuation
Solution Approach 1:
The patent replaces mechanical interlock systems with an inductive coupling system using electromagnetic fields. The base contains a transmitter coil that generates an electromagnetic field, and the container has a receiver coil that detects this field. When properly coupled, the receiver detects the transmitter's signal and enables motor operation. This eliminates mechanical arms, links, springs, and switches, resolving the contradiction by substituting a more reliable electromagnetic system for the fragile mechanical one.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the base and container to establish the interlock relationship. Instead of direct mechanical contact, the electromagnetic field serves as the mediator that communicates the proper coupling state. The transmitter coil generates the field, and the receiver coil detects it, allowing the system to determine if the container is properly attached without mechanical contact points that could fail.
2Reliability
If mechanical interlock systems are used to ensure lid is in place, then safety is improved, but cleaning becomes difficult
Solution Approach 1:
The patent replaces mechanical interlock components with electromagnetic coupling elements. The transmitter and receiver coils are positioned to couple through the container wall without requiring mechanical contact points that would trap food particles. This substitution eliminates the cleaning difficulties associated with mechanical arms, links, and switches while maintaining reliable lid position verification through electromagnetic field detection.
3Reliability
If specific container-base combinations are required, then proper functioning is ensured, but versatility is reduced
Solution Approach 1:
The patent implements a universal electromagnetic coupling system where the base contains a transmitter coil that can communicate with receiver coils in various container types. The electromagnetic field penetrates through different container materials and designs, allowing a single base unit to work with multiple container styles, sizes, and configurations. This resolves the contradiction by creating a universal interface that maintains reliable coupling detection across diverse container types.
Solution Approach 2:
The patent uses electromagnetic field parameters (frequency, strength, coupling coefficient) to detect and adapt to different container-base combinations. The system can adjust to variations in container material, thickness, and geometry by monitoring the electromagnetic coupling characteristics. This allows the system to maintain reliable operation across different container types without requiring specific mechanical configurations for each combination.

Function Achieved in This Case
The NFC-based system prevents motor operation unless the lid and container are correctly interlocked, ensures proper container identification, and tracks usage, enhancing reliability, ease of cleaning, and versatility by allowing any compatible container to be used with the blender base.
Implementation Method 1
The container may comprise a near field communications (NFC) chip that may receive power and communicate with an NFC component of a blender base when the container and the blender base are interlocked.
