Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blenders require separate components for lid detection, which can be contaminated, interfere magnetically, and spoil the transparent design, necessitating high power transmission and complex coil configurations.
Innovation Solution
A blender design using a single induction coil in the main body and container body for inductive coupling, with a transparent conductive member for electrical connection, allowing accurate lid detection with low power and maintaining transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional blender is used to blend hot liquids, then the blending function is provided, but the risk of injury to the user increases due to ejection of hot liquid
Solution Approach 1:
The patent applies beforehand cushioning by providing a vented lid with a removable cap that allows controlled steam escape before blending hot liquids. This prevents pressure buildup and potential ejection of hot liquid during operation, cushioning the user against injury risk while maintaining the blending function.
Solution Approach 2:
The patent introduces an intermediary element - the vented lid with removable cap - that mediates between the hot liquid inside the container and the external environment. This intermediary allows controlled steam venting while preventing uncontrolled ejection of hot liquid, thus protecting the user during hot liquid blending operations.
2Quantity of substance
If the blender container is made larger to accommodate more ingredients, then the blending capacity increases, but the stability of the blender base decreases
Solution Approach 1:
The patent addresses stability by adding a handle to the container, which provides an additional dimension for user control and balancing. This allows users to manually stabilize the container during operation, compensating for the reduced stability caused by larger container size while maintaining increased blending capacity.
3Difficulty of detecting and measuring
If the blender container is made transparent to monitor blending progress, then the visibility improves, but the strength of the container decreases
Solution Approach 1:
The patent applies local quality by making only the side walls of the container transparent while keeping the base and lid opaque. This allows visibility of blending progress through the sides while maintaining structural strength through the opaque base and lid, which bear the primary mechanical loads.
4Stability of the object's composition
If a fixed lid is used on the blender container to prevent spillage, then the containment improves, but the ability to access ingredients during blending is reduced
Solution Approach 1:
The patent applies dynamics by providing a lid that can be opened during operation. The lid transitions from a closed state (providing containment) to an open state (allowing ingredient access), enabling the system to adapt between these two requirements during the blending process.
Solution Approach 2:
The patent segments the lid into a main lid body and a removable cap component. This segmentation allows the cap to be removed for ingredient access while the main lid body remains in place to maintain containment, enabling both functions to coexist through modular design.
5Ease of repair
If the blender container is designed for easy disassembly to clean parts, then the ease of repair improves, but the device complexity increases
Solution Approach 1:
The patent segments the container into distinct components (container body, lid, cap, handle) that can be easily separated from each other. This segmentation enables easy disassembly for cleaning without requiring complex mechanisms, as each part can be independently removed and cleaned.
Solution Approach 2:
The lid serves multiple functions: it provides containment during blending, allows steam venting when the cap is removed, and can be opened during operation for ingredient access. This multi-functionality reduces the need for additional separate components, maintaining simplicity while enabling easy disassembly for cleaning.

AI summary
Proposed is a blender (1) in which when the closure of a container lid (20) of a container body (10) is detected, a main body (30) operates. In the blender (1), a transparent conductive member (161) is disposed to electrically connect an upper end part of the container body (10) with a lower end part of the container body (10), and when the closure of the container lid (20) is detected, power is transmitted from a first induction coil (101) of the main body (30) to a second induction coil (201) of the container body (10), and when receiving the change of the current of the first induction coil (101) caused by a magnetic field of the second induction coil (201) generated by the power transmitted to the second induction coil, the main body (30) recognizes the closure of the container lid (20) and operates.
