Solution Overview

Problem

Existing cooking systems face challenges in achieving optimal lighting and display properties while maintaining low costs and flexibility, particularly in the attachment of filter elements to mounting plates, which can lead to quality issues and increased complexity in production and logistics.

Innovation Solution

Attaching the filter element directly to the display unit rather than the mounting plate, allowing for better lighting control, reduced costs, and increased design freedom, with the filter element and film being securely attached using an adhesive connection to prevent unintentional detachment and simplify assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the filter element is attached to the mounting plate, then the lighting and display properties can be optimized, but the production costs increase and flexibility decreases

Engineering Contradiction:
Improvelighting qualityVSAvoidproduction cost
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent uses a film as a copy or representation of the filter element's function. The film is attached to the mounting plate and works in conjunction with the filter element attached to the display unit, allowing the lighting control function to be distributed and achieved more cost-effectively than attaching a single large filter element directly to the mounting plate.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The filtering function is segmented into two parts: the filter element attached to the display unit and the film attached to the mounting plate. This segmentation allows each component to be optimized independently and attached to different substrates, reducing overall system cost while maintaining lighting control functionality.

Inventive Principle:
Principle #1Segmentation

2Illumination intensity

If the filter element is attached to the mounting plate, then the lighting control is improved, but the design flexibility and freedom decrease

Engineering Contradiction:
Improvelighting controlVSAvoiddesign flexibility
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

By segmenting the filtering function between the filter element on the display unit and the film on the mounting plate, the design becomes more flexible. The filter element can be independently selected and attached to different display units without being constrained by mounting plate supplier limitations, enabling greater design freedom and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The configuration allows for dynamic adaptation in design choices. Different filter elements with various wavelength ranges can be selected and attached to display units, enabling the system to adapt to different lighting requirements and design preferences without being locked into a fixed mounting plate design.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If the filter element is attached to the mounting plate, then the lighting properties are optimized, but the risk of damage during production and transport increases

Engineering Contradiction:
Improvedisplay propertiesVSAvoiddamage risk
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

Segmenting the filtering components between the display unit and mounting plate reduces the size and fragility of individual components. The filter element attached to the display unit is less prone to damage during handling and transport compared to a large filter element attached to the entire mounting plate, thereby improving reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The film attached to the mounting plate serves as a protective layer that cushions and protects the filter element during assembly and transport. This beforehand protection reduces the risk of damage to the filter element, maintaining system reliability.

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

4Illumination intensity

If the filter element is attached to the mounting plate, then the lighting control is improved, but the complexity of production and logistics increases

Engineering Contradiction:
Improvelighting controlVSAvoidproduction complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

Dividing the filtering function into two separate attachable components (filter element on display unit, film on mounting plate) simplifies production and logistics. Each component can be manufactured, tested, and attached independently, reducing the complexity of assembling and managing a single integrated filter system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular configuration allows for dynamic assembly and disassembly, simplifying production workflows. The filter element can be attached to the display unit separately from the mounting plate assembly, enabling parallel production processes and reducing bottlenecks in the manufacturing and logistics chain.

Inventive Principle:
Principle #15Dynamics
