Solution Overview

Problem

Kitchen and catering appliances lack user-friendly and simple manufacturing solutions, particularly in integrating rotating units with touch displays for control, which complicates design and maintenance.

Innovation Solution

A rotating unit with touch elements that can be attached to a touch display surface, allowing for user input via sweeping and pressing actions without wired connections, enabling easy integration and maintenance by using capacitive touch technology and flexible coverings for enhanced detection accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a rotating unit with touch elements is integrated into the touch display surface, then user input detection accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveuser input detection accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The rotating unit is integrated directly into the touch display surface, merging the rotation detection functionality with the existing touch display structure. The touch elements are incorporated into the touch display layer, eliminating the need for separate detection mechanisms and reducing overall device complexity while maintaining detection accuracy.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The touch display surface serves multiple functions: it acts as both the display interface and the detection interface for the rotating unit. The same touch display technology detects both touch inputs and rotational movements, eliminating the need for dedicated detection hardware and simplifying the device architecture.

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

2Reliability

If the rotating unit is firmly attached to the surface, then reliability is improved, but ease of manufacture worsens

Engineering Contradiction:
ImprovereliabilityVSAvoidease of manufacture
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The rotating unit is designed as a separate module that can be independently manufactured and then attached to the touch display surface. This segmentation allows each component to be optimized and manufactured separately using standard processes, improving ease of manufacture while ensuring reliable attachment through dedicated mounting interfaces.

Inventive Principle:
Principle #1Segmentation

3Reliability

If wired connections are used for transmitting information from the rotating unit, then reliability is improved, but device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mechanical wired connection system is replaced with a wireless communication system. The rotating unit transmits information to the control unit wirelessly, eliminating the need for physical cables and connectors. This reduces device complexity by removing wiring infrastructure while maintaining reliable data transmission through wireless protocols.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
