Innovation Solution
A Lever Functional Trainer with a post and carriage system allowing flexible placement of user Bar handles, utilizing iso-linear bars and cables for rapid reconfiguration, enabling multiple exercise variations and accommodating different user sizes and sizes, and including pulleys or/and ball bearings for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional resistance training equipment is used, then the machine structure is simple, but the flexibility to accommodate users of different sizes and exercise preferences is poor
Solution Approach 1:
The patent implements a universal resistance training machine that can perform multiple exercises and accommodate users of different sizes through a standardized modular system. The adjustable components including the post with multiple holes, movable carriage, and interchangeable handles allow a single machine to serve various exercise needs, eliminating the requirement for multiple specialized machines.
Solution Approach 2:
The machine is divided into independent modular components: a vertical post with spaced holes, a movable carriage that can be positioned at different heights, interchangeable handles, and adjustable cables. Each component can be independently adjusted or reconfigured to create different exercise configurations, providing versatility without requiring complete machine replacement.
2Productivity
If traditional resistance training equipment is used, then the machine structure is fixed, but the reconfiguration time for varying exercises is slow
Solution Approach 1:
The machine transitions from a fixed structure to a dynamic, adjustable system where the carriage can be quickly repositioned along the post, handles can be interchanged, and cable attachments can be rapidly reconfigured. This dynamic design enables fast adaptation between different exercises without lengthy setup times.
Solution Approach 2:
The post is pre-drilled with multiple holes at standardized intervals, and the carriage is designed with pre-positioned attachment points that align with these holes. This preliminary preparation of the structure allows for rapid reconfiguration by simply moving the carriage to the next required position or swapping pre-designed handle assemblies, rather than making custom adjustments.
3Productivity
If traditional resistance training equipment is used, then the weight system uses weight plates, but the reconfiguration of resistance is slow
Solution Approach 1:
The traditional mechanical weight plate system is replaced with a cable-and-pulley mechanism that allows for quicker resistance adjustments. The cable system can be rapidly reattached to different points on the carriage or post, enabling fast resistance changes without the need to physically handle and stack multiple weight plates.
4Ease of operation
If traditional resistance training equipment is used, then the machine requires a spotter for safety, but the usability is reduced
Solution Approach 1:
The machine incorporates self-spotting features through its design, including controlled-release mechanisms on the carriage that allow users to quickly disengage the weight stack in case of failure, and adjustable cable tensions that can be set to provide automatic resistance reduction at the end of the range of motion. These features enable safe operation without requiring a spotter.

AI summary
The Lever Functional Trainer is a resistance exercise machine, the New Lever Functional Trainer is comprised of a linear guide such as a post with a carriage on the post (the lever bar), surrounding the post or portion of, as well as a second carriage of the functional trainer type below, the post has holes spaced along the front (but not limited to the front), the carriages can connect to these holes to lock in position, the functional carriage has two loops (or one or more) that allow at least one end to be pulled by the user, shrinking the loop until the flexible element generates a force upon the resistance, such as a weight stack (but not limited to a weight stack), the cable or flexible element is connected from the functional trainer carriage to the resistance element by a plethora of pulleys or rollers, the lever bar when in position can be unlocked to acts such as an iso-linear press or pull motion because there are two handles and bars connecting to the main bar carriage (via an axle or axles, but not limited to such) from several starting positions because of a pin on the side of the post with holes spaced along the side(s) of the post, each side of the independently or combined (with a pin joining both sides) movable lever bar sides (also handles) has a hook for one none of the flexible elements ends (connected to a carabiner each) for connecting the functional carriage below to the lever bar above.
