Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hole is formed in the transparent window for acoustic output, then sound can be output to the outside, but foreign substances may enter and block the passage
Solution Approach 1:
A waterproof member is introduced as an intermediary component between the acoustic passage and the external environment. This member allows sound waves to pass through while blocking foreign substances, effectively resolving the contradiction between maintaining acoustic functionality and preventing blockages.
Solution Approach 2:
The waterproof member is designed with porous or mesh-like structures that permit acoustic wave transmission while physically blocking foreign substances. The porous nature allows air and sound to pass through, yet the mesh structure prevents intrusion by larger objects.
2Stability of the object's composition
If an air vent passage is formed to equalize air pressure, then pressure equilibrium is maintained, but waterproof performance deteriorates
Solution Approach 1:
The waterproof member serves as a mediator in the air vent passage, allowing air molecules to pass through for pressure equalization while blocking water and foreign substances. This resolves the contradiction by enabling pressure equilibrium without compromising waterproof integrity.
Solution Approach 2:
The waterproof member utilizes porous or mesh structures that permit gas permeation for air pressure equalization while physically preventing liquid water from entering. The porous design allows selective passage based on the size and nature of the substance.
3Reliability
If a waterproof member is added to prevent blockages, then foreign substance protection is improved, but device complexity increases
Solution Approach 1:
The waterproof member is designed to perform multiple functions simultaneously: blocking foreign substances, maintaining waterproof performance, and allowing acoustic wave transmission and air flow. By consolidating these functions into a single component, device complexity is minimized while reliability is improved.
Solution Approach 2:
The use of porous or mesh materials allows a single component to achieve both protection and permeability. The mesh structure provides blocking capability for foreign substances while maintaining open pathways for sound and air, reducing the need for separate components.
4Adaptability or versatility
If the acoustic passage and air vent passage are separated, then functional independence is improved, but device complexity increases
Solution Approach 1:
The acoustic passage and air vent passage are merged into a single integrated passage structure, eliminating the need for separate passages. The waterproof member is positioned within this unified structure to provide both acoustic output and pressure equalization functions, reducing structural complexity while maintaining functional independence.
Solution Approach 2:
The integrated passage structure serves multiple functions: acoustic wave transmission, air pressure equalization, and foreign substance blocking. By combining these functions into a single passage system, the design reduces complexity while maintaining the adaptability and versatility of independent functional control.
