Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical movement is used in the timer, then the timer can be operated by rotating the scale cover, but the operation is complex and error-prone requiring multiple steps
Solution Approach 1:
The patent replaces the traditional mechanical movement with a quartz movement body that uses electronic timing mechanisms. The scale cover rotation is simplified to directly drive a traveling wheel that interacts with a PCB-based timing circuit, eliminating the complex multi-step mechanical spring winding and positioning mechanisms while achieving accurate timing through electronic control.
2Object-affected harmful factors
If a mechanical movement is used in the timer, then the timer can provide timing function, but it generates continuous ticking noise that disturbs users
Solution Approach 1:
The patent substitutes the noisy mechanical movement with a quartz movement body that operates electronically. The quartz crystal oscillator provides stable timing signals without mechanical contact, eliminating the continuous ticking noise while maintaining high timing accuracy through electronic counting and display mechanisms.
3Measurement precision
If a mechanical movement is used in the timer, then the timer can be constructed simply, but the timing error is large
Solution Approach 1:
The patent employs a quartz movement body utilizing quartz crystal oscillation properties to generate highly stable frequency signals. This electronic timing system achieves superior timing accuracy compared to mechanical movements, with the quartz crystal's natural resonance providing consistent timekeeping that is insensitive to temperature and mechanical wear variations.
Solution Approach 2:
The patent changes the fundamental operating parameter from mechanical rotation and spring tension to quartz crystal electrical oscillation. This parameter change enables precise timing control through electronic circuits that can accurately count oscillation cycles, achieving high measurement precision while the modular quartz movement structure keeps the overall device complexity manageable.
4Reliability
If the scale cover is rotated directly to the timing position without proper initialization, then the operation is simplified, but the prompt ringtone becomes extremely short
Solution Approach 1:
The patent incorporates a limiting assembly that performs preliminary action by automatically positioning the traveling wheel within a valid timing range before the actual timing function activates. This preliminary positioning ensures that regardless of the user's initial rotation position, the timer will function correctly and generate the full-duration prompt ringtone, eliminating the need for users to understand complex initialization procedures.
