Abdominal Exercise Station with Pivoting Headrest and Shared Weight Stack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abdominal exercise devices often lack integration with multi-station exercise apparatuses, limiting the variety and effectiveness of abdominal muscle workouts, and do not efficiently provide adjustable resistance during crunch exercises.
Innovation Solution
A multi-station exercise apparatus with an abdominal exercise station featuring a pivotally connected head/neck pad and hand grips, utilizing a shared weight stack for resistance, which can be docked as a fixed headrest for other exercises, and providing increasing resistance through cable routing and pulley mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate abdominal exercise device is used, then abdominal muscle workout effectiveness is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines the abdominal exercise station with other exercise stations (press exercise station, high pulley station, or leg extension/leg curl station) into a single integrated multi-station exercise apparatus. The head/neck pad assembly is pivotally connected to the common frame, allowing multiple exercise functions to share the same structural platform and weight stack system, thereby reducing overall device complexity while maintaining abdominal workout effectiveness.
Solution Approach 2:
The head/neck pad assembly serves multiple functions: it acts as a resistance mechanism for abdominal crunch exercises when pivoted, and serves as a fixed headrest for other exercises when docked in the retracted position. This multi-functionality allows the apparatus to provide both abdominal exercise capability and support for other exercises without requiring separate dedicated components for each function.
2Ease of operation
If a dedicated weight stack for abdominal exercises is provided, then resistance adjustability is improved, but device complexity and weight stack size increase
Solution Approach 1:
The patent implements a shared weight stack system where a single weight stack serves multiple exercise stations including the abdominal exercise station. The cable routing system allows the same weight stack to provide resistance for abdominal crunches, press exercises, and other stations, eliminating the need for separate dedicated weight stacks and reducing overall device complexity while maintaining resistance adjustability through the common weight selection mechanism.
3Stability of the object's composition
If the head/neck pad remains fixed during other exercises, then stability for other exercises is improved, but versatility for abdominal exercises is lost
Solution Approach 1:
The head/neck pad assembly is designed with pivotal connectivity to the frame, allowing it to dynamically change position based on the exercise being performed. During abdominal crunches, the pad pivots forward to engage the user's head/neck and provide resistance. During other exercises, the pad is docked in a retracted position to serve as a stable fixed headrest. This dynamic positioning capability enables the system to maintain stability for non-abdominal exercises while preserving abdominal exercise versatility.
Solution Approach 2:
The head/neck pad assembly is designed as a separate, movable component that can be independently positioned relative to the main frame. This segmentation allows the pad to be detached from its docked position and pivoted into the exercise position, providing abdominal exercise functionality without interfering with the stability requirements of other exercises when in the docked state.

AI summary
A multi-station exercise apparatus includes a station for performing abdominal exercises. The abdominal exercise station is combined with another exercise station, such as a press exercise station, a high pulley station or a leg extension/leg curl station. The apparatus for performing an abdominal exercise includes a pad for the head and/or neck of the exerciser that is pivotally connected to the frame of the exercise machine. A pair of hand grips are connected to the head/neck pad and disposed so that the exerciser may grasp the hand grips in order to pull forward in a “crunch” exercise. Exercise resistance is provided by means such as a weight stack that is shared by the various stations of the exercise machine. The head/neck pad may be “docked” when not performing an abdominal exercise to prevent looseness and serve as a fixed headrest for other exercises.
