Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports training aids fail to effectively train and condition the coordinated rotational movements of the pelvis, upper-torso, and arms for optimal power and sequencing in rotational sports, particularly lacking in simplicity and portability.
Innovation Solution
A sports training system comprising an adjustable hip harness, torso harness, flexible connectors, and cords that provide resistance or assistance to simulate the rotational movements, allowing users to practice proper sequencing and timing of pelvic and upper-torso rotations, along with arm synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanical stand with rigid saddle and vest is used to train hip and torso motions, then training effectiveness is improved, but device complexity and cost increase, and portability decreases
Solution Approach 1:
The training system is divided into separate modular components: a flexible vest with attachment points, elastic cords, and external anchors. This segmentation allows each component to perform its specific function independently while maintaining overall training effectiveness, reducing device complexity compared to integrated rigid systems.
Solution Approach 2:
The patent replaces rigid mechanical structures with flexible elements. The vest is made of flexible material that can move with the user's body, and elastic cords provide flexible resistance. This flexibility maintains training effectiveness while dramatically reducing device complexity and improving portability compared to rigid mechanical stands.
2Adaptability or versatility
If multiple harnesses and connectors are added to train coordinated upper-torso and pelvic movements, then training capability is improved, but device complexity increases
Solution Approach 1:
The flexible vest serves multiple functions: it anchors elastic cords for resistance training, provides attachment points for various exercise configurations, and moves with the user's body. This multi-functionality allows the single vest component to replace what would otherwise require multiple separate harnesses and connectors, maintaining training capability while reducing device complexity.
Solution Approach 2:
The system uses dynamic elastic cords instead of rigid connectors, allowing the training apparatus to adapt to various movement patterns and exercise types. The elasticity enables the same basic setup to train different muscle groups and movement sequences, increasing training capability without adding complex mechanical structures.
3Manufacturing precision
If rigid frames and multiple belt loops are used to constrain pelvic motion, then motion control is improved, but ease of operation and portability worsen
Solution Approach 1:
The patent replaces rigid frames with flexible elastic cords that provide resistance while allowing natural movement ranges. The flexible vest conforms to the user's body shape, providing motion control through elastic resistance rather than rigid constraint. This approach maintains adequate motion control for training purposes while dramatically improving ease of operation and portability.
Solution Approach 2:
The elastic cords allow adjustment of resistance parameters by changing cord tension, length, or attachment points, providing motion control adaptable to different user needs and exercise types. This parameter flexibility replaces the need for fixed rigid structures, improving ease of operation while maintaining sufficient motion control.

AI summary
A rotational sports training and conditioning system has a hip harness, a torso harness, a pair of adjustable connectors that connect diagonally from the torso harness to the hip harness, an elongated cord and a club band. The hip and torso harnesses each have selectively positioned cord loops for attachment of the cord and/or the club band. The connectors selectively synchronize relative rotation of the pelvis and torso for swing, strike or throw training and conditioning. The cord assists or resists rotational motions. The club band synchronizes arm positioning and forearm rotation with rotation of the pelvis and upper torso.
