Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lower warning threshold is used to ensure high sensitivity and safety, then the voltage detector triggers at greater distances, but it causes excessive triggering when working with medium and high-voltage lines
Solution Approach 1:
The patent implements dynamic adjustment of the warning threshold through a control unit that allows users to modify the threshold value based on the specific work environment. This resolves the contradiction by making the threshold adaptable rather than fixed, enabling high sensitivity when needed while preventing excessive triggering in medium and high-voltage contexts.
Solution Approach 2:
The patent changes the operational parameter (warning threshold) from a fixed value to an adjustable value. The control unit enables modification of the threshold parameter according to different user needs and environmental conditions, thereby resolving the contradiction between high sensitivity and excessive triggering.
2Reliability
If different voltage detectors are provided for different user groups and requirements, then each detector can be optimized for its specific purpose, but it results in high procurement, storage and maintenance costs
Solution Approach 1:
The patent makes a single voltage detector universal by equipping it with a control unit that allows adjustment of the warning threshold to suit different user groups and work environments. This eliminates the need for multiple specialized detectors, reducing procurement, storage, and maintenance costs while maintaining optimized performance for various applications.
Solution Approach 2:
The detector becomes dynamically adaptable to different user needs through adjustable threshold settings. Instead of requiring static specialized detectors for each user group, the system allows dynamic configuration to serve multiple purposes with a single device.
3Ease of operation
If a charging connection (e.g., USB interface) is provided in the voltage detector housing, then the voltage source can be recharged, but it requires an opening in the housing that allows dirt and moisture to enter
Solution Approach 1:
The patent replaces the mechanical charging connection (physical USB interface requiring housing openings) with wireless charging technology. This substitution eliminates the need for physical openings in the housing, thereby preventing dirt and moisture ingress while maintaining the recharging capability.
Solution Approach 2:
Wireless charging acts as an intermediary that transfers energy without requiring physical contact or openings. The inductive charging field serves as the mediator between the charging source and the voltage source, enabling recharging while keeping the housing sealed.
4Object-affected harmful factors
If additional sealing of the charging connection is provided to prevent dirt and moisture ingress, then the housing protection is improved, but it significantly increases the design effort
Solution Approach 1:
The patent eliminates the need for complex sealing mechanisms by replacing the mechanical charging connection with wireless charging. This substitution removes the source of the problem entirely, avoiding the need for additional sealing design and its associated complexity.
Solution Approach 2:
The charging connection opening is completely removed from the housing design through the adoption of wireless charging. By extracting the physical interface, the patent eliminates the need for sealing measures and their associated design complexity.
