Solution Overview
Problem
Blenders suffer from sagging of the upper surface casing, leading to malfunction and decreased manipulation sensitivity due to heat generation in electronic parts and inadequate support, resulting in inaccurate user input and potential errors.
Innovation Solution
A support member is provided under the upper surface of the main body casing to prevent sagging, and a touch module is supported to enhance manipulation precision, with air circulation designed to dissipate heat away from the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic parts (motor assembly and PCB module) are installed in the main body to enable blender operation, then the blender functionality is improved, but heat is generated causing malfunction and reduced reliability
Solution Approach 1:
The patent converts the harmful heat generated by electronic parts into a beneficial cooling effect by designing an air circulation path where air flows through the PCB module and motor assembly, absorbing heat and dissipating it outside, thus preventing overheating and malfunction
2Ease of manufacture
If the upper surface of the main body casing is made flexible or thin to improve manufacturing ease, then manufacturing is simplified, but the casing sags under pressure causing manipulation errors and malfunction
Solution Approach 1:
The patent segments the main body casing into an upper casing and a lower casing, with the support member positioned between them to provide structural reinforcement. This segmentation allows the upper surface to remain thin and easy to manufacture while preventing sagging through the intermediate support structure
Solution Approach 2:
The support member acts as an intermediary element between the upper and lower casings, providing mechanical support to prevent sagging of the upper surface while maintaining the overall structure's integrity and ease of manufacture
3Device complexity
If the PCB module is placed under the manipulation part to reduce device complexity, then the structure is simplified, but the manipulation sensitivity decreases and input accuracy is reduced
Solution Approach 1:
The patent positions the PCB module in a different spatial dimension (under the manipulation part) rather than directly beneath it, allowing the manipulation part to maintain its sensitivity while the PCB is supported by the lower casing structure, thus reducing complexity without sacrificing precision
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 support member stabilizes the casing, preventing malfunctions and improving touch sensitivity, while the air circulation effectively cools electronic parts, enhancing user safety and operational reliability.
Implementation Method 1
a cooling fan at the lower end of a rotary shaft of the motor assembly and rotating when the motor assembly is driven to force air flow in the inside of the body
Implementation Method 2
an air guide which connects the motor assembly to the plate drain port to thereby form a discharge path of air
