Retractable Training Harness Tether to Prevent Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training harnesses with reins or tethers are cumbersome to store and pose a hazard of entanglement, particularly for children learning sports like skiing or snowboarding, as they can get tangled with the child's limbs or equipment, such as chair lifts.
Innovation Solution
A retractable tether system with a casing supporting a rotatable spool, an elastic section, and a handle grip, allowing for reversible coupling to anchor points on a training harness, which can be easily stored and extended, reducing the risk of entanglement and providing adjustable guidance during training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional rein or tether is used to guide and assist the child's body posture or motion, then the learning process is expedited, but the tether becomes a hazard by becoming entangled with the child's limbs or on structures
Solution Approach 1:
The patent applies the dynamics principle by implementing a retractable tether mechanism that can dynamically extend and retract. The tether is stored in a retractable mechanism attached to the harness, allowing it to be extended when guidance is needed and retracted when not in use, thereby reducing entanglement hazards while maintaining learning efficiency
Solution Approach 2:
The patent extracts the tether from being a separate, bulky component and integrates it into the harness system through a retractable mechanism. The tether is stored within the harness structure itself, eliminating the need for separate storage and reducing the risk of entanglement with external structures
2Ease of operation
If a traditional rein or tether is used for training, then guidance and assistance are provided, but the tether is awkward and bulky to store
Solution Approach 1:
The patent applies the nested doll principle by placing the tether inside a retractable mechanism that is integrated into the harness. The tether is nested within the harness structure, allowing it to be stored compactly without requiring additional external storage space, thereby reducing bulk while maintaining guidance capability
Solution Approach 2:
The retractable mechanism allows the tether to dynamically change between an extended state for guidance and a retracted state for compact storage. This dynamic capability enables the tether to be easily stored within the harness structure without being awkward or bulky
3Object-affected harmful factors
If a retractable tether mechanism is implemented, then storage is improved and entanglement risk is reduced, but the device complexity increases
Solution Approach 1:
The retractable tether mechanism is designed to be self-contained and automatically retract the tether when not in use. The mechanism serves itself by incorporating the storage and retrieval functions within the harness structure, reducing the need for additional complex external components while maintaining low entanglement risk
