Hemispherical Grip Handle for Balanced Triceps Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing triceps ropes disproportionately focus resistance on the long head of the triceps muscles, neglecting the lateral head, and hinder maximal skeletal joint articulation due to their thick, inflexible design, limiting exercise efficiency and freedom of movement.
Innovation Solution
A hemispherical grip handle with a thin, flexible latex sheath and an enlarged gripping surface that allows for an open palm style grip, distributing resistance evenly to both triceps heads and providing optimal comfort and movement freedom, replacing traditional triceps ropes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a thick, inflexible rope design is used for triceps ropes, then durability and structural integrity are improved, but freedom of movement and exercise efficiency deteriorate
Solution Approach 1:
The patent replaces the traditional thick rope with a thin, flexible cable that has sufficient strength but allows for greater freedom of movement and improved exercise efficiency. The flexible cable maintains structural integrity while enabling a fuller range of motion during triceps exercises.
Solution Approach 2:
The patent changes the physical parameters of the rope by reducing its diameter and increasing its flexibility. This parameter change allows the cable to bend more easily and accommodate the natural movement patterns of the arm and elbow joint, thereby improving freedom of movement while maintaining adequate strength through proper cable construction.
2Ease of operation
If a traditional hammer-style grip is used on triceps ropes, then ease of gripping is improved, but resistance distribution to triceps heads becomes unbalanced, neglecting the lateral head
Solution Approach 1:
The patent introduces a hemispherical grip attachment that provides a curved, ergonomic surface for hand placement. This spherical geometry allows the user to position their hand in an open palm configuration rather than a hammer grip, enabling proper engagement of both the lateral and long heads of the triceps muscles simultaneously.
Solution Approach 2:
The hemispherical grip attachment serves as an intermediary between the cable and the user's hand. This intermediate component transforms the cable into a form that facilitates proper hand positioning and muscle engagement, mediating the force transmission to ensure balanced resistance distribution across all triceps heads.
3Stability of the object's composition
If cable attachment points are located some distance away from the gripping point, then structural stability is improved, but control and freedom of movement during exercise deteriorate
Solution Approach 1:
The patent segments the cable handle into distinct functional components: the cable attachment point and the gripping point are separated by an intermediate section. This segmentation allows the cable to attach at one location while providing a hemispherical grip at another, enabling both structural stability and user control to be optimized independently.
Solution Approach 2:
The patent resolves the spatial conflict between attachment point and gripping point by utilizing the third dimension. The hemispherical grip extends perpendicular to the cable axis, allowing the user to grip at a location that is both distance-wise and dimensionally separated from the attachment point, thereby maintaining stability while improving control.

AI summary
A hemispherical grip member has an outer hemispherical surface and a grip layer and a grip member opening. A length of aircraft cable having a first cable end extends through the opening and is crimped in position onto the grip member with a cable nut. A connector is provided on an opposite cable end. A length of a soft flexible tubing surrounds the cable between the grip member and the connector. When a user grasps the hemispherical surface of the grip member, the first cable end is located inside the grasp of the user and the cable and tubing passes between two fingers of the user.
