Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal housing with electromagnetic shielding is used, then electromagnetic shielding effectiveness is improved, but the size of heat dissipation holes is restricted and appearance is limited
Solution Approach 1:
The housing is divided into a first housing part and a second housing part that can relatively move, with an adjustable belt connecting them. This segmentation allows the opening size between the two parts to be adjusted, enabling both electromagnetic shielding (when closed) and heat dissipation (when opened) functions to be achieved with the same structure.
Solution Approach 2:
The adjustable belt allows dynamic adjustment of the opening size between the first and second housing parts. The belt can be positioned at different locations to create openings of varying sizes, transforming the static housing into a dynamic structure that adapts to different thermal and aesthetic requirements while maintaining electromagnetic shielding when needed.
2Temperature
If the opening size is increased for heat dissipation, then heat dissipation performance is improved, but electromagnetic shielding effectiveness deteriorates
Solution Approach 1:
The system dynamically adjusts the opening size through the adjustable belt mechanism. When heat dissipation is needed, the belt is positioned to create larger openings; when electromagnetic shielding is prioritized, the belt closes the openings. This dynamic adjustment allows the system to adapt to different operational requirements without permanent structural compromise.
Solution Approach 2:
The adjustable belt can be periodically repositioned based on operational needs, alternating between closed positions for electromagnetic shielding and open positions for heat dissipation. This periodic adjustment allows the device to cycle between different functional states as required by varying operational conditions.
3Ease of manufacture
If a fixed housing structure is used for electromagnetic shielding, then manufacturing simplicity is improved, but adaptability to different usage modes deteriorates
Solution Approach 1:
The housing is segmented into movable parts connected by an adjustable belt, allowing the structure to transition from a simple fixed design to an adaptable configuration. The segmentation enables different usage modes (closed for shielding, open for heat dissipation) while maintaining relatively simple manufacturing of individual components.
Solution Approach 2:
The adjustable belt mechanism serves multiple functions: it connects the housing parts, enables opening size adjustment, and provides adaptability to different usage modes. This multi-functional element adds versatility without requiring completely separate structures for each function, maintaining manufacturing efficiency while enhancing adaptability.
