Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical switching method using a spring piece is used to power the printed circuit board, then the battery box can be turned on and off, but the spring piece suffers damage and contact reliability deteriorates, shortening the device's life
Solution Approach 1:
The patent replaces the purely mechanical spring piece switching system with an electro-acoustic transducer-based system. The electro-acoustic transducer converts sound signals into electrical signals to control the switching, eliminating the need for repeated mechanical pressing of the spring piece. This substitution resolves the contradiction by maintaining ease of operation through voice control while dramatically improving contact reliability by removing the mechanical wear component.
Solution Approach 2:
The patent introduces a change-over switch as an intermediary component that mediates between the spring piece and the printed circuit board. This change-over switch can be controlled by either the spring piece or the electro-acoustic transducer, allowing the system to switch between mechanical and voice-controlled modes. The intermediary protects the spring piece from direct contact wear while maintaining the option for mechanical operation.
2Device complexity
If only a spring piece is used for switching, then the structure remains simple, but the device lacks flexibility in switching modes and requires continuous mechanical operation
Solution Approach 1:
The patent applies multi-functionality by designing the battery box to support two switching modes: traditional mechanical switching via the spring piece and voice-controlled switching via the electro-acoustic transducer. The change-over switch serves as a universal component that can be actuated by either method. This resolves the contradiction by maintaining structural simplicity through a single switch mechanism while dramatically increasing versatility through multiple activation methods.
3Productivity
If the spring piece is pressed repeatedly to turn on and off the battery box, then power can be supplied to the printed circuit board, but the spring piece and contact suffer wear and damage
Solution Approach 1:
The patent replaces the mechanical spring piece pressing system with an electro-acoustic transducer that converts sound signals into electrical signals for switching control. This substitution maintains the power supply capability while eliminating the mechanical wear that limited service life. The electro-acoustic transducer has no moving parts that wear, dramatically extending the device's operational duration.
Solution Approach 2:
The electro-acoustic transducer enables the system to respond to external sound signals automatically, eliminating the need for manual spring piece pressing. The system serves itself by detecting sound waves and converting them into the electrical signals needed for switching, reducing user interaction and mechanical wear while maintaining productivity.
