Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the electronic pen is embedded in the electronic device, then the portability is improved, but the slimness of the electronic device deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidslimness
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The electronic pen is accommodated within a dedicated pen accommodating part formed in the housing of the foldable electronic device. The pen storing module includes a receiving space that nestles the electronic pen, allowing it to be stored internally without significantly increasing the overall device volume. This nesting approach enables the pen to be integrated into the device structure while maintaining portability and slimness.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the electronic pen is arbitrarily attached to an outer surface through magnetic force, then the portability is improved, but the stability of attachment deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The electronic pen is nested within a dedicated pen accommodating part with a receiving space, rather than being arbitrarily attached to the outer surface. This structured nesting provides stable attachment while maintaining portability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Magnetic force is utilized to replace traditional mechanical attachment mechanisms. The magnetic attachment module includes a magnetic body that magnetically attracts the electronic pen, providing stable attachment without complex mechanical structures. This allows the pen to be securely held while maintaining ease of attachment and detachment.

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

3Ease of operation

If the electronic pen is arbitrarily attached to an outer surface, then the ease of attachment is improved, but the risk of loss and damage increases

Engineering Contradiction:
Improveease of attachmentVSAvoidrisk of loss and damage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The electronic pen is nested within a dedicated pen accommodating part with a receiving space, providing a secure and designated storage location. This structured approach reduces the risk of loss compared to arbitrary attachment, while the magnetic force enables easy attachment and detachment.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Magnetic force provides a reliable attachment mechanism that is both secure and easy to operate. The magnetic attraction force is sufficient to prevent loss during normal use, while allowing simple attachment and detachment by the user. This replaces less reliable mechanical attachment methods.

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

4Stability of the object's composition

If a pen accommodating part is formed in the housing, then the stability of pen storage is improved, but the device complexity increases

Engineering Contradiction:
Improvepen storage stabilityVSAvoidstructural complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The pen accommodating part is formed as an integrated structure within the housing, creating a nested receiving space. This approach provides stable pen storage while avoiding the need for separate, complex attachment mechanisms. The pen storing module is incorporated into the existing housing structure, minimizing additional complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The pen accommodating part serves multiple functions: it provides a stable storage space, integrates with the magnetic attachment system, and can work with the wireless charging system. By designing this component to fulfill multiple roles, the overall device complexity is reduced despite the added functionality.

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