Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide cords and battery recharging systems are used, then the screening arrangement can operate, but the mounting becomes complicated and the system becomes complex
Solution Approach 1:
The patent removes the guide cords and battery recharging systems from the screening arrangement, replacing them with a direct electrical connection system. The electrical contacts are integrated into the side rails and bottom element, eliminating the need for separate mounting of guide cords and recharging components, thus simplifying both mounting and reducing system complexity.
Solution Approach 2:
The patent replaces the mechanical guide cord system with an electrical connection system. Instead of using physical cords to guide and power the bottom element, the invention uses electrical contacts and guides that provide both mechanical guidance and electrical power transmission through the same structural components.
2Adaptability or versatility
If batteries with recharging system are used, then the screening arrangement can operate autonomously, but the mounting precision requirements increase and risk of damage occurs
Solution Approach 1:
The patent removes the batteries and recharging system entirely, replacing autonomous operation with continuous electrical power supply through fixed contacts. This eliminates the need for precision mounting of rechargeable components and removes the risk of incomplete charging or battery damage.
Solution Approach 2:
The patent introduces electrical guides and contact means as intermediaries between the power outlet and the motor. These intermediaries provide continuous electrical connection during movement, eliminating the need for precision-aligned rechargeable components while maintaining autonomous operation capability.
3Use of energy by moving object
If plug and socket system for battery recharging is used, then batteries can be recharged, but the mounting process becomes complicated and precision is required
Solution Approach 1:
The patent removes the plug and socket recharging system, replacing battery recharging with continuous electrical power supply through integrated contacts. This eliminates the need for separate recharging components and simplifies the mounting process while maintaining energy supply functionality.
Solution Approach 2:
The patent combines the electrical power transmission and mechanical guidance functions into a single integrated system. The electrical guides and contact means serve both to guide the bottom element movement and to transmit electrical power continuously, eliminating the need for separate recharging components.
4Device complexity
If electrical contact means are integrated into side rails, then the power supply is simplified and mounting is easier, but the side rails require additional components
Solution Approach 1:
The patent merges the electrical contact functionality with the side rail structure. The electrical guides and contact means are integrated into the side rails, combining mechanical support and electrical power transmission functions in single components, thus simplifying the overall power supply system while maintaining manufacturing feasibility.
