Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a liquid supply part contacts a liquid introduction port for liquid supply, then liquid can be supplied from the storage container to the consumption device, but variations in dimension, environmental changes, and repeated attachment/detachment cause poor contact and unstable liquid supply

Engineering Contradiction:
Improveliquid supply stabilityVSAvoidcontact quality between porous member and introduction port
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The biasing member applies a continuous elastic force to the porous member, enabling it to dynamically adapt to dimensional variations and environmental changes. This dynamic adjustment ensures consistent contact pressure between the porous member and the liquid introduction port, maintaining reliable liquid supply despite external conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing member changes the physical state of the porous member by applying continuous pressure, which compensates for dimensional variations and wear from repeated attachment/detachment. This parameter change ensures the porous member maintains optimal contact with the introduction port for stable liquid supply.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If a porous member is used for liquid supply, then liquid can flow through holes in the porous member, but dimensional variations and deterioration cause poor contact with the liquid introduction port

Engineering Contradiction:
Improveliquid supply speedVSAvoidcontact consistency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The biasing member enables the porous member to dynamically adjust its position and contact pressure, ensuring consistent alignment with the liquid introduction port. This dynamic adjustment maintains both the speed and reliability of liquid supply over time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing member pre-positions the porous member in optimal contact with the liquid introduction port before liquid supply begins. This preliminary action ensures that the porous member is already properly aligned and pressurized, enabling immediate and reliable liquid flow.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the porous member is pressed against the liquid introduction port for good contact, then liquid supply stability improves, but the porous member may deteriorate faster due to repeated attachment and detachment

Engineering Contradiction:
Improveliquid supply stabilityVSAvoidporous member lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The biasing member uses elastic deformation as a buffer, absorbing mechanical stress from repeated attachment and detachment. This parameter change in the elastic material allows the porous member to maintain contact pressure while reducing wear and extending its operational life.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If the porous member is made resilient to maintain contact, then liquid supply remains stable during attachment and detachment, but the structure becomes more complex

Engineering Contradiction:
Improveliquid supply stability during attachment/detachmentVSAvoidstructure of liquid supply part
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The biasing member is integrated directly into the liquid supply part structure, combining the support and biasing functions into a single unified component. This merging reduces overall structural complexity while maintaining the resilient contact necessary for stable liquid supply during attachment and detachment.

Inventive Principle:
Principle #5Merging (Combining)
