Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heat treatment is performed on the printed model to improve properties, then the strength and durability of the printed object are improved, but deformation occurs during heat treatment affecting shape and size precision
Solution Approach 1:
The patent applies the anti-weight principle by introducing a support medium (liquid or gas) that provides buoyant force to counterbalance the gravitational force acting on the printed model during heat treatment. This counterforce prevents deformation by offsetting the weight-induced stress on the model structure, allowing heat treatment to proceed without shape or size distortion.
Solution Approach 2:
The patent employs an intermediary medium (support liquid or gas) that acts as a mediator between the printed model and the heat treatment environment. This intermediary provides both mechanical support to prevent deformation and a controlled atmosphere for uniform heat distribution, resolving the contradiction between improving material properties and maintaining dimensional accuracy.
2Duration of action of stationary object
If heat treatment is performed on the printed model to improve properties, then the durability of the printed object is improved, but deformation occurs during heat treatment affecting size precision
Solution Approach 1:
The support medium provides buoyant force that counteracts gravity's effect on the printed model during heat treatment. This prevents gravitational deformation that would otherwise alter the model's size and dimensions, ensuring that durability improvements from heat treatment do not come at the cost of dimensional accuracy.
Solution Approach 2:
The intermediary support medium serves dual functions: providing mechanical support to maintain size precision and creating a controlled heat treatment environment. This mediator enables the model to achieve improved durability through prolonged heat exposure while maintaining its original dimensions.
3Productivity
If conventional heat treatment is performed without support medium, then the process is simple and fast, but deformation occurs reducing manufacturing precision
Solution Approach 1:
The patent introduces a support medium as an intermediary that enables simultaneous achievement of high productivity and high precision. The medium allows for rapid heat treatment while preventing deformation, thus maintaining processing speed without sacrificing dimensional accuracy.
Solution Approach 2:
The patent utilizes hydraulic (liquid) or pneumatic (gas) principles by employing a fluid support medium that provides buoyant support to the printed model. This approach maintains simplicity and speed of the heat treatment process while eliminating deformation through fluid mechanical support, achieving both high productivity and dimensional accuracy.
