Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof coating is applied on the circuit board and wiring system, then waterproof feature is provided, but processing complexity increases and manufacturing cost increases
Solution Approach 1:
The patent replaces the chemical waterproof coating process with a mechanical sealing structure consisting of a waterproof housing, gaskets, and sealed compartments. This mechanical approach eliminates the need for complex coating applications while providing reliable waterproofing through physical barriers and sealing mechanisms.
Solution Approach 2:
The controller is divided into separate sealed modules including a waterproof housing containing the circuit board, a separate wiring system with sealed connectors, and distinct functional compartments. This segmentation allows each module to be independently sealed and replaced, reducing overall system complexity while maintaining waterproof integrity.
2Reliability
If a waterproof coating is applied on the circuit board and wiring system, then waterproof feature is provided, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive waterproof coating processes with standardized mechanical sealing components such as pre-fabricated gaskets, sealed housings, and modular connectors. These mechanical solutions reduce manufacturing complexity and cost while providing equivalent or superior waterproof protection.
Solution Approach 2:
The modular sealed design allows individual components to be replaced without replacing the entire controller. If a specific module fails or needs upgrading, only that module needs to be removed and replaced, reducing waste and manufacturing costs associated with complete unit replacement.
3Reliability
If the circuit board and wiring system are coated with waterproof coating to form an integrated member, then waterproof feature is provided, but modularity is reduced and repairability is limited
Solution Approach 1:
The controller is divided into separate sealed modules including a waterproof housing containing the circuit board, a separate wiring system with sealed connectors, and distinct functional compartments. This segmentation allows each module to be independently sealed and replaced, reducing overall system complexity while maintaining waterproof integrity.
Solution Approach 2:
The modular sealed design allows individual components to be replaced without replacing the entire controller. If a specific module fails or needs upgrading, only that module needs to be removed and replaced, reducing waste and manufacturing costs associated with complete unit replacement.
4Ease of operation
If conductive rubber is used for electrical contact, then command signal generation is achieved, but terminal oxidation occurs and reliability decreases over time
Solution Approach 1:
The patent replaces the conductive rubber contact mechanism with a wireless communication system using antennas and radio frequency circuits. This eliminates the mechanical contact between conductive rubber and PCB terminals, preventing oxidation issues while maintaining command signal generation capability through wireless transmission.
5Adaptability or versatility
If pivot-button type passive wireless switch is used to generate command signals, then multiple command signals can be generated, but the structure becomes complex and functionality is limited for intelligent control systems
Solution Approach 1:
The patent replaces the mechanical pivot-button switching mechanism with a wireless communication module that generates command signals through software control and signal processing. This allows multiple command signals to be generated from a simpler actuation mechanism, reducing mechanical complexity while maintaining or enhancing functionality for intelligent control systems.
