Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional 3D printing methods are used on fabric, then printing can be performed, but adhesion and structural integrity are insufficient
Solution Approach 1:
The printing process is divided into two distinct stages: first printing an adhesion structure layer, then printing the object layers. This segmentation allows each layer type to be optimized independently for its specific function, resolving the contradiction between achieving adhesion and maintaining structural integrity.
Solution Approach 2:
The adhesion structure is printed and cured before the object layers are deposited. This preliminary action creates a prepared surface that enhances subsequent adhesion, ensuring reliable bonding from the start rather than attempting to achieve it during or after object formation.
2Adaptability or versatility
If uniform curing radiation is applied, then printing process is simple, but adhesion structure and object layers cannot be optimized differently
Solution Approach 1:
Different curing radiation intensities are applied to different layer types: higher intensity for adhesion structure layers to maximize bonding, and lower intensity for object layers to preserve material properties. This local differentiation resolves the contradiction between adaptability and complexity by making the system responsive to local requirements.
Solution Approach 2:
The curing radiation intensity is dynamically adjusted based on the layer type being cured. The system transitions from static uniform curing to dynamic adaptive curing, allowing optimization of each layer while managing complexity through automated control.
3Manufacturing precision
If multiple nozzle arrays are used for dispensing, then material deposition precision improves, but device complexity increases
Solution Approach 1:
Multiple nozzle arrays are integrated into a single printing head assembly that can dispense different materials (adhesion formulation and building material) through different nozzles. This multi-functional design achieves high precision material deposition while consolidating complexity into a unified structure rather than requiring separate devices.

AI summary
A method of forming an object on a fabric by three-dimensional printing, comprises: printing on the fabric an adhesion structure having a stack of layers in a configured pattern corresponding to a shape of a bottommost surface of the object, wherein for each layer of the stack the printing comprises dispensing and curing a first formulation along a scanning direction. The method also comprises printing the object onto the stack by dispensing and curing a building formulation in layers along the direction in configured patterns corresponding to shapes of slices of the object. Optionally, the curing comprises irradiating the layer by creating a pattern of curing radiation that scans the layer along the direction, wherein the pattern has a shape of a single stripe.
