Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hand jacks are used, then the device complexity is low, but the ease of operation deteriorates due to difficulty in use and improper usage
Solution Approach 1:
The patent replaces traditional manual mechanical jacks with an electrically-powered jack system. The electric motor-driven jack mechanism eliminates the need for manual cranking and complex hand jack operations, providing automated lifting control through electronic switches while maintaining structural simplicity through integrated design.
Solution Approach 2:
The system incorporates automatic safety features including sensors that detect proper jack placement and vehicle stability conditions. The control system automatically prevents operation unless safety criteria are met, eliminating the need for user judgment and expertise while maintaining simple operation through intuitive switch controls.
2Reliability
If jacks are made more powerful and stable, then the reliability improves, but the device complexity increases due to additional control systems
Solution Approach 1:
The patent combines multiple functions into integrated components: the control system merges power management, safety monitoring, and operation control into a unified electronic control unit. The jack system integrates motor control, position sensing, and safety interlocks into a single coordinated mechanism, reducing overall system complexity while enhancing reliability.
Solution Approach 2:
The system incorporates sensors that provide real-time feedback on jack position, vehicle stability, and operational status. This feedback enables automatic control adjustments and safety validations, ensuring reliable operation through continuous monitoring without requiring complex manual control systems.
3Illumination intensity
If lights are added to improve visibility, then the illumination intensity improves, but the use of energy increases
Solution Approach 1:
The patent employs lighting that operates periodically or on-demand rather than continuously. The lights are activated only when the jack system is in use or when safety illumination is required, reducing overall energy consumption while providing adequate illumination intensity during critical operations through controlled lighting cycles.

AI summary
A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.
