Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If light and light holder are fixed by welding, then connection strength is improved, but ease of replacement deteriorates
Solution Approach 1:
The lighting device is divided into separable modules: a light holder component and a light source component. The light source component can be independently removed and replaced without affecting the light holder, enabling easy maintenance while maintaining structural integrity during use.
Solution Approach 2:
The welding connection is replaced with a magnetic field-based wireless power supply system. The light holder component contains a wireless power supply module with a first magnetic element, and the light source component contains a wireless electric receiving module with a second magnetic element. The magnetic elements enable automatic alignment and secure positioning without permanent bonding, allowing easy replacement while maintaining strong operational connection.
2Reliability
If custom-made LED lighting devices are produced, then optical characteristics and heat dissipation requirements are met, but manufacturing cost increases
Solution Approach 1:
The light holder component is designed as a universal base that can accommodate different light source components through standardized magnetic coupling. The wireless power supply module in the light holder provides power to various light sources without requiring custom wiring or mounting solutions, enabling mass production of standardized holders while maintaining customized optical performance through different light source selections.
Solution Approach 2:
By separating the light holder component (containing power supply and heat dissipation structures) from the light source component, each can be optimized and produced independently. The standardized light holder can be mass-produced to reduce costs, while light sources can be selected or customized based on specific optical requirements without increasing overall manufacturing complexity.
3Ease of repair
If wireless power supply module is used, then ease of replacement is improved, but device complexity increases
Solution Approach 1:
The wireless power supply module integrates multiple functions into a single component: wireless power transmission, magnetic coupling for mechanical attachment, and electrical connection. This consolidation simplifies the overall structure compared to traditional wired systems with separate connectors, wires, and mounting mechanisms, while enabling easy replacement through simple magnetic coupling.
