Innovation Solution
The proposed attachment assembly includes a cradle with side and bottom fastening means, a mounted fan for cooling, and attenuating elements made of soft materials to absorb shocks and vibrations, ensuring efficient airflow and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If resilient means are provided for coupling the cradle member to the mounting plate, then vibration isolation is improved, but the device complexity increases
Solution Approach 1:
The patent combines the cradle member and mounting plate into a single integrated component, eliminating the need for separate resilient means. This merging approach maintains vibration isolation benefits while reducing device complexity by removing the coupling element and associated fastening mechanisms.
Solution Approach 2:
The cradle member is designed to perform multiple functions simultaneously: it provides structural support, enables vibration isolation through its flexible material properties, and serves as the mounting interface. This multi-functionality eliminates the need for separate dedicated components for each function.
2Object-affected harmful factors
If 2 cradles are used to form a suspension for the electronic device, then vibration isolation is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the functionality of multiple cradles into a single cradle member that provides comprehensive vibration isolation. This single component approach reduces part count, simplifies assembly, and lowers manufacturing costs while maintaining the vibration isolation performance previously requiring multiple cradles.
3Stability of the object's composition
If movement limiters are provided to prevent undue motion of the cradle, then motion control is improved, but the device complexity increases
Solution Approach 1:
The patent integrates motion control functionality directly into the cradle member structure itself, eliminating the need for separate movement limiters. The cradle member's geometry and material properties provide the necessary motion constraints, reducing device complexity while maintaining stability.
4Reliability
If a closed casing design is used for the appliance, then protection is improved, but cooling efficiency deteriorates
Solution Approach 1:
The patent introduces localized ventilation openings in the casing that provide targeted cooling airflow to the electronic device without compromising overall protection. These localized openings allow controlled air intake for cooling while maintaining the sealed protection of the remaining casing structure.
