Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between support element and base element, then structural stability is improved, but vibration decoupling deteriorates
Solution Approach 1:
The patent uses a pneumatic connection (air spring) between the support element and base element. The air spring provides a flexible connection that decouples vibrations while maintaining structural stability through controlled air pressure. The air cushion acts as a vibration isolator while supporting the weight and providing stable mounting for the mobile terminal.
Solution Approach 2:
The patent employs a flexible wall element that can be elastically deformed to create the air spring structure. This flexible element allows relative movement between support and base elements while maintaining the enclosed air volume, enabling vibration decoupling through elastic deformation and air compression.
2Strength
If the wall element is made rigid, then structural strength is improved, but vibration decoupling and cooling function deteriorate
Solution Approach 1:
The flexible wall element is designed with sufficient elasticity to allow deformation for vibration decoupling while maintaining structural integrity. The flexibility enables the wall to deform under vibration loads and allow air flow for cooling, yet retain enough strength to enclose the air spring volume and support operational loads.
Solution Approach 2:
The patent optimizes the flexibility parameter of the wall element to achieve the right balance between strength and flexibility. By controlling the elastic properties and geometric design of the wall, it can withstand structural loads while allowing sufficient deformation for vibration isolation and maintaining air flow pathways for cooling.
3Temperature
If openings are added for air flow, then cooling function is improved, but structural integrity deteriorates
Solution Approach 1:
The wall element is designed with openings or perforations that allow air flow through the air spring volume for cooling the mobile terminal. These openings are strategically positioned and sized to provide adequate cooling airflow while maintaining sufficient structural integrity of the wall element through proper distribution and dimensioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves simultaneous optimal vibration decoupling and cooling by utilizing an air spring effect and air flow, effectively dissipating heat while minimizing vibration transmission.
Implementation Method 1
the support element and the base element are connected by way of an at least regionally flexible wall element in such a way that a closed volume designed to act as an air spring or as an air cushion is formed
Implementation Method 2
a closed volume designed to act as an air spring or as an air cushion is formed between the support element and the base element. This advantageously makes it possible to obtain optimal vibration decoupling
Implementation Method 3
The volume is able to be flowed through. This expediently makes it possible to discharge heat, that is to say in particular heat introduced into the volume for example by way of a mobile terminal, such as a smartphone
