Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the head unit is disposed in the water purifier requiring space for filter connection, then the filter assembly can be properly configured, but it becomes difficult to replace filters in narrow spaces

Engineering Contradiction:
Improvefilter replacementVSAvoidspace requirement
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The filter assembly is divided into separate components: the head unit with connection mechanisms and the filter cartridges. This segmentation allows the filters to be independently removed and replaced without requiring significant space for complex disassembly operations, making filter replacement feasible even in narrow installation spaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection mechanism between the head unit and filter cartridges employs dynamic elements such as elastic members and detachable connections. These dynamic features enable quick attachment and detachment of filters without requiring permanent fixed installations, facilitating easy filter replacement in space-constrained environments.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the head unit and filter are connected with pipes, then water flow is established, but pipe connection operations become complex and time-consuming

Engineering Contradiction:
Improveinstallation simplicityVSAvoidpipe connection
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connection functions are merged into an integrated mechanism where the head unit directly connects to the filter cartridges through built-in connection interfaces. This eliminates the need for separate pipe connection operations, as the housing walls themselves serve as the connection medium, significantly simplifying the installation process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The complex pipe connection system is extracted and replaced with a simplified direct connection mechanism. The elastic members and detachable connection features are introduced to create a straightforward attach-detach system that eliminates cumbersome piping operations while maintaining reliable water flow connections.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If water leaks from the head unit or filter during replacement, then the replacement process is simple, but electronic equipment may fail or the purifier becomes contaminated

Engineering Contradiction:
Improvefilter replacementVSAvoidwater leakage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Sealing mechanisms are incorporated into the connection design between the head unit and filter cartridges. These sealing features prevent water leakage during the filter replacement process, protecting electronic equipment and preventing contamination while maintaining the simplicity of the replacement operation.

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

4Adaptability or versatility

If multiple filters are connected in parallel, then installation is straightforward, but different filter types cannot be connected in series reducing filtration efficiency

Engineering Contradiction:
Improvefilter configuration flexibilityVSAvoidwater filtering efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The head unit is designed with universal connection interfaces that can accommodate different types of filter cartridges. The connection mechanism supports both parallel and series configurations, allowing users to mix and match different filter types based on their specific water quality requirements while maintaining straightforward installation procedures.

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