Blender Knob Assembly Support Structure to Prevent Control Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blenders face issues with the structural support of protruding control buttons, which can lead to damage and displacement, and lack a neat outer appearance due to the placement of control buttons and display screens.
Innovation Solution
A blender design featuring a knob assembly that protrudes outwardly through the main body, supported by internal supporters to prevent rearward pushing and maintain structural integrity, with a light guide system using LEDs to indicate operational states without a separate display screen, enhancing user interaction and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control button protrudes from the front surface of the base part, then the user can easily operate the blender through simple manipulation, but the control button may be structurally pushed to the rear and damaged by strong forces
Solution Approach 1:
The patent applies beforehand cushioning by providing a support structure that extends from the rear of the base part to support the control button before any pushing force is applied. This support structure prevents the control button from being pushed too far rearward and protects internal components from damage, addressing the reliability issue while maintaining the protruding design for ease of operation.
2Loss of information
If both the control button and display screen are provided on the base part, then the blender can display cooking programs and operational states, but the outer appearance of the front surface becomes cluttered and not neat
Solution Approach 1:
The patent applies another dimension by moving the display screen from the front surface of the base part to the side surface of the base part. This spatial relocation allows both the control button and display screen to be provided without cluttering the front surface, maintaining a neat outer appearance while preserving full information display functionality.
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 design securely supports the knob assembly, preventing damage and maintaining its position under force, while providing intuitive operational feedback and a cleaner exterior appearance by integrating light-based state indication.
Implementation Method 1
a light guide configured to guide the light emitted from the LEDs toward the knob ring
