Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal casings are used in smart wearable devices, then structural strength and durability are improved, but weight increases and signal transmission accuracy deteriorates
Solution Approach 1:
The casing is divided into multiple segments: metal casings for structural strength and non-metallic casings for signal transmission. This segmentation allows each material to be used where it provides the most benefit, resolving the contradiction between strength and weight/signal quality.
Solution Approach 2:
Different materials are used in different locations of the casing. Metal materials are used in areas requiring structural strength, while non-metallic materials are used in areas requiring good signal transmission properties. This local differentiation resolves the contradiction by optimizing material placement.
2Strength
If metal casings are used in smart wearable devices, then structural strength is improved, but signal transmission accuracy deteriorates
Solution Approach 1:
The casing is segmented into metal and non-metallic portions, allowing signal transmission areas to be made of non-metallic materials that do not interfere with electromagnetic signals, while metal portions provide structural strength where needed.
Solution Approach 2:
Non-metallic materials are specifically used in areas where signal transmission occurs, while metal materials are used in areas requiring structural support. This local material selection resolves the contradiction between strength and signal accuracy.
3Weight of moving object
If device weight is reduced for comfort, then wearing comfort is improved, but structural strength may deteriorate
Solution Approach 1:
The casing uses a composite structure combining metal and non-metallic materials. This composite approach reduces overall weight compared to full metal construction while maintaining structural strength through the metal components, resolving the contradiction between weight and strength.
4Measurement precision
If non-metallic materials are used in the casing, then signal transmission accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The casing is segmented into metal and non-metallic parts, which can be manufactured separately using appropriate processes and then assembled. This segmentation manages manufacturing complexity by allowing specialized manufacturing for each material type while achieving the signal transmission benefits of non-metallic materials.
