Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to provide electrical power to devices on a movable carriage, then electrical power can be transmitted to the devices, but the wired connections are susceptible to damage, dislodgement, and require complex installation during assembly
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless power transmission system using electromagnetic fields. The wireless power transmitter and receiver eliminate physical cables and connectors, thereby removing the reliability issues of wired connections (damage, dislodgement) and simplifying installation complexity.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium to transfer power between the stationary power source and the movable carriage. This intermediary enables power transmission without direct physical contact, resolving the contradiction between reliable power delivery and connection simplicity.
2Duration of action of moving object
If wired connections are used to provide electrical power to devices on a movable carriage, then electrical power can be transmitted to the devices, but the wired connections may become loose or dislodge during repeated movements
Solution Approach 1:
The wireless power transmission system replaces mechanical wired connections with electromagnetic field-based power transfer. This substitution eliminates the stability problems associated with repeated movements, as there are no physical connections to become loose or dislodge during carriage motion.
Solution Approach 2:
The system is designed to dynamically maintain power transmission during carriage movement by using electromagnetic fields that can accommodate the motion without requiring physical reconnection or adjustment of cables.
3Ease of manufacture
If wired connections are used to provide electrical power to devices on a movable carriage, then electrical power can be transmitted to the devices, but the installation process is difficult and time consuming
Solution Approach 1:
The wireless power transmission system eliminates the need for installing wired connections, including routing cables, attaching connectors, and ensuring proper mechanical fastening. This substitution dramatically simplifies the installation process and reduces assembly time.
Solution Approach 2:
The patent extracts and removes the wired connection components (cables, connectors, mounting hardware) from the system, leaving only the wireless power transmitter and receiver. This extraction eliminates the complex installation steps associated with wired connections.

AI summary
A wireless power system for an exercise machine for providing electrical power wirelessly to an electrical energy storage device or electrical energy consuming device attached to a movable carriage of an exercise machine. The wireless power system for an exercise machine generally includes an exercise machine which includes a frame having one or more rails. A carriage is movably positioned upon the rails to allow an exerciser to move the carriage when performing an exercise. A wireless power receiver is attached to the carriage that wirelessly receives electrical energy transferred from a wireless power transmitter. An electrical energy storage device or an electrical energy consuming device attached to the movable carriage is electrically connected to the wireless power receiver to receive electrical power from the wireless power receiver.
