Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If flexible material is used to achieve a tight fit around the target object, then the mould can conform to the object shape, but the deployment becomes labor-intensive and time-consuming

Engineering Contradiction:
Improvetight fitVSAvoiddeployment time
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The mould membrane is designed as a resiliently deformable structure that can dynamically change its shape and volume. By applying mechanical force to manipulation structures, the membrane transitions between expanded and contracted states, enabling automated deployment and removal while maintaining tight fit during encapsulation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mould membrane is divided into multiple manipulation structures distributed across its surface. Each manipulation structure can be independently controlled to deform the membrane locally, allowing precise control over the overall shape and fit without requiring manual manipulation of the entire membrane

Inventive Principle:
Principle #1Segmentation

2Shape

If flexible material is used to achieve a tight fit, then the mould can match the object shape, but extraction becomes difficult without damaging the encapsulated substance

Engineering Contradiction:
Improvetight fitVSAvoidextraction difficulty
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The resiliently deformable membrane can be mechanically expanded to increase the space within, creating clearance between the membrane and the encapsulated target object. This dynamic expansion capability enables easy extraction of the mould without disturbing the cured substance, while maintaining tight fit during the encapsulation process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The volume and shape parameters of the membrane are changed by applying mechanical force to manipulation structures. By increasing the internal space through controlled deformation, the membrane transitions from a tight-fit state during encapsulation to an expanded state for easy removal

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If manual handling is used for deployment, then the flexible material can be positioned, but the process requires large amounts of time and labor

Engineering Contradiction:
Improvepositioning capabilityVSAvoidprocess speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Manual mechanical manipulation is replaced by a controlled system where mechanical force is applied to manipulation structures through automated means. This substitution maintains the positioning capability while dramatically reducing labor requirements and process time

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

Solution Approach 2:

The membrane structure includes built-in manipulation structures that enable self-deployment and self-positioning when mechanical force is applied. The system is designed to be manipulated into its functional shape without requiring external manual handling, improving both speed and automation potential

Inventive Principle:
Principle #25Self-service

4Shape

If the inner diameter of the membrane body is less than the outer diameter of the target object, then the membrane can form a tight fit, but the target object cannot be inserted without deforming the membrane

Engineering Contradiction:
Improvetight fitVSAvoidmembrane deformation control
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The membrane is designed to be resiliently deformable, allowing temporary expansion during insertion and automatic return to its original tight-fit configuration once the target object is in place. This dynamic behavior simplifies the insertion process while ensuring precise fit

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The manipulation structures are positioned and configured in advance to control the deformation sequence. By pre-positioning these structures, the membrane deforms in a controlled manner during insertion, reducing complexity and ensuring proper alignment

Inventive Principle:
Principle #10Preliminary action
