Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal components (housing) are used to protect the electronic device, then mechanical strength and protection are improved, but antenna performance deteriorates due to signal induction and loss
Solution Approach 1:
The housing is divided into a first housing portion and a second housing portion, with the antenna disposed between them. This segmentation allows the antenna to be positioned in a region free from metal interference while the metal housing portions remain for structural protection.
Solution Approach 2:
An insulating member is introduced as an intermediary component between the antenna and the metal housing portions. This insulating member prevents direct contact between the antenna and metal, reducing signal induction and interference while maintaining the protective function of the metal housing.
2Strength
If metal housing is used for device protection, then structural integrity is improved, but signal transmission efficiency deteriorates
Solution Approach 1:
The housing is segmented into separate portions with the antenna positioned between them, creating a metal-free zone for signal transmission while maintaining overall structural integrity through the segmented metal portions.
Solution Approach 2:
The insulating member acts as a mediator that allows the metal housing to maintain structural integrity while preventing harmful electromagnetic induction, thus preserving signal transmission efficiency.
3Ease of manufacture
If metal components are used in the electronic device, then manufacturing robustness is improved, but reception efficiency deteriorates due to signal induction
Solution Approach 1:
The housing is divided into separate manufacturable portions that can be produced using standard metal manufacturing processes, maintaining manufacturing robustness while the segmented structure naturally creates isolation zones for the antenna.
Solution Approach 2:
The insulating member is introduced as a simple intermediary component that can be easily integrated into the manufacturing process, preventing signal induction issues while maintaining the ease of manufacturing metal components.
