Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user touches the button on the screen during taking a picture, then the photographing operation is performed, but the hand holding the portable terminal becomes shaken and the posture becomes unstable
Solution Approach 1:
The system uses the user's own portable terminal to trigger photographing operations. The terminal detects the user's presence and automatically initiates the capture process, eliminating the need for manual button pressing that causes hand shaking. The terminal serves both as the control device and the stability reference point.
Solution Approach 2:
The patent introduces an intermediate system that mediates between the user and the photographing operation. Instead of direct hand-to-button contact, the user's terminal acts as an intermediary that detects presence and triggers the capture automatically, reducing the mechanical interaction that causes instability.
2Length of moving object
If a selfie stick is used to perform a selfie, then the photographing range is extended, but the background remains limited to a narrow range
Solution Approach 1:
The system transitions from a single fixed photographing point to multiple distributed photographing stages throughout the indoor space. By adding the spatial dimension of multiple locations, users can capture diverse backgrounds while maintaining extended reach capabilities at each stage.
Solution Approach 2:
The patent divides the indoor space into multiple discrete photographing stages, each equipped with its own image capture unit. This segmentation allows users to access different locations with distinct backgrounds, overcoming the limitation of a single narrow background view.
3Adaptability or versatility
If multiple indoor photographing stages are deployed, then diverse backgrounds are available, but the system complexity increases
Solution Approach 1:
Each photographing stage uses standardized image capture units that can operate in multiple modes (selfie mode and security mode). This universality reduces overall system complexity by using identical components throughout, despite the increased number of stages.
Solution Approach 2:
The system incorporates pressure sensors that detect user presence and automatically trigger the appropriate image capture unit. This feedback mechanism simplifies operation and reduces the need for complex user interfaces, managing system complexity through automated control.
4Adaptability or versatility
If image capture units are installed at multiple locations, then images with various backgrounds can be captured, but the cost and device complexity increase
Solution Approach 1:
The patent employs identical image capture units with dual functionality (selfie and security modes) at all locations. This multi-functionality reduces the need for specialized equipment, thereby controlling costs and complexity while maintaining versatile image capture capabilities.
Solution Approach 2:
The system uses replicated copies of the same image capture unit design across multiple locations. This standardization allows for economies of scale in manufacturing and simplifies maintenance and upgrades, managing complexity despite the increased number of components.
