Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic hand shake correction is enabled to improve image quality, then image stability is improved, but heat generation and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the hand shake correction function adjustable rather than fixed. The correction accuracy is dynamically changed based on detected temperature or remaining battery capacity, allowing the system to adapt its performance characteristics to current operational conditions and resolve the contradiction between image stability and heat generation.
Solution Approach 2:
The patent changes the parameter of correction accuracy based on temperature or battery capacity detection results. When temperature exceeds a threshold or battery capacity is low, the correction accuracy is reduced, directly addressing the contradiction by adjusting the operational parameters to balance performance with thermal and power constraints.
2Reliability
If electronic hand shake correction accuracy is increased to improve image quality, then image stability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts correction accuracy based on detected battery capacity, making the hand shake correction function adaptable to power availability. This resolves the contradiction between image stability and power consumption by allowing higher accuracy when power is abundant and reducing accuracy when power is constrained.
Solution Approach 2:
The correction accuracy parameter is changed based on battery capacity detection results. When battery capacity is low, the system reduces correction accuracy to conserve power, directly addressing the contradiction between maintaining image stability and managing power consumption.
3Temperature
If camera function is turned off to reduce heat generation, then heat generation is reduced, but user experience deteriorates
Solution Approach 1:
Instead of abruptly turning off the camera function when temperature exceeds thresholds, the system dynamically adjusts correction accuracy. This gradual adjustment maintains camera operation and user experience while still managing heat generation, resolving the contradiction between reducing heat and maintaining ease of operation.
Solution Approach 2:
The system prepares for thermal management by having multiple correction accuracy levels ready. When temperature approaches thresholds, it gradually reduces accuracy before complete shutdown would be necessary, cushioning the transition and maintaining user experience while managing heat generation.
4Temperature
If specific functions are turned on or off to manage heat generation, then heat generation is controlled, but bodily sensation of user changes drastically
Solution Approach 1:
The system applies dynamics by making correction accuracy continuously adjustable rather than using discrete on/off states. This gradual adjustment prevents drastic changes in user experience while still effectively controlling heat generation, resolving the contradiction between thermal management and user comfort.
Solution Approach 2:
The system changes the correction accuracy parameter in response to temperature detection results, providing smooth transitions rather than abrupt functional changes. This resolves the contradiction by maintaining user comfort through gradual parameter adjustment while still controlling heat generation effectively.
