Solution Overview

Problem

Existing blenders face issues with the structural support of control buttons, which can lead to damage from strong forces and displacement, and the appearance of the front surface becomes cluttered with both control buttons and display screens.

Innovation Solution

A blender design that includes a main body with a securely mounted knob assembly protruding outward, supported by a PCB device with LEDs for intuitive operation and state visualization, eliminating the need for a separate display screen and maintaining a neat appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a control button protruding from the front surface is provided for operation input, then ease of operation is improved, but reliability deteriorates due to potential damage from strong forces and displacement

Engineering Contradiction:
Improveoperation inputVSAvoidcontrol button stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control button is nested within a recessed cavity in the front surface, with the button body positioned inside the recess and only the operating portion protruding. This nested structure allows the button to be pressed inward without risk of displacement or external damage, while maintaining ease of operation through the protruding operating surface.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The recessed cavity structure provides beforehand cushioning by creating a protective space that absorbs the force of button pressing. The cavity walls and bottom provide structural support that prevents the button from being damaged or displaced when strong forces are applied during operation.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Loss of information

If both control button and display screen are provided on the base part, then information display is improved, but device complexity worsens due to cluttered appearance

Engineering Contradiction:
Improveoperation state displayVSAvoidfront surface structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The control button and display screen are merged into a single integrated unit. The control button serves dual functions: as an operation input device and as a display medium. Operation states are indicated through visual feedback on the button surface itself (such as LED indicators or light emission), eliminating the need for a separate display screen and simplifying the front surface structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control button is designed with multi-functionality, serving both as an input device for operation selection and as an output device for displaying operation states. This universal design allows a single component to fulfill multiple functions, reducing overall device complexity while maintaining full information display capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles
