Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery is permanently enclosed within the device, then the device structure is simplified and manufacturing is easier, but the battery cannot be replaced or upgraded, reducing device longevity and user experience
Solution Approach 1:
The device is divided into separable modules: a housing containing the battery and electronic components, and a wearable portion. The housing can be detached and replaced, allowing the battery to be upgraded or replaced without replacing the entire device, thus maintaining manufacturing simplicity while enabling adaptability.
Solution Approach 2:
The device transitions from a static, permanently assembled structure to a dynamic, reconfigurable system. The detachable housing allows the device to adapt its configuration over time, enabling battery replacement and upgrades while maintaining ease of manufacture through modular assembly processes.
2Duration of action of moving object
If the battery size is increased to extend charge life, then the operating duration is improved, but the device weight and volume increase, affecting user comfort
Solution Approach 1:
By separating the battery into a removable housing module, the system allows selective replacement of battery units with different capacities. Users can choose lighter, smaller batteries for portability or larger batteries for extended charge life, decoupling the weight-duration tradeoff from the overall device design.
Solution Approach 2:
The system enables parameter changes in battery capacity, weight, and dimensions by allowing replacement of the battery housing with different configurations. This permits optimization of the charge life-to-weight ratio based on specific user needs without redesigning the entire device.
3Manufacturing precision
If the device components are integrated into a unified structure, then manufacturing precision and assembly are improved, but repair and component replacement become more difficult
Solution Approach 1:
The device employs segmented modular architecture where the battery and electronic components are housed in a separate, detachable housing module. This maintains precise manufacturing within each module while enabling easy replacement of the entire housing or individual components without affecting the precision of other device parts.
Solution Approach 2:
The battery and associated components are extracted from the main wearable structure and placed in a separate removable housing. This extraction maintains the precision integration needed for the primary device functions while allowing straightforward removal and replacement of the housing module for repair or upgrading purposes.
