Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional training devices (metal and/or full cover systems) are used, then training function is provided, but installation time increases (up to 20 min to install and remove)
Solution Approach 1:
The training device is divided into multiple detachable components including spring bands, elastic bands, extender straps, and ground stakes. These segmented components can be quickly assembled and disassembled, reducing installation time from 20 minutes to under 2 minutes while maintaining the training function.
Solution Approach 2:
The device uses dynamic, flexible components rather than rigid fixed structures. The spring bands and elastic bands can be quickly attached and detached, allowing the system to adapt its configuration rapidly between different training scenarios without time-consuming reinstallation.
2Reliability
If conventional training devices (metal and/or full cover systems) are used, then training function is provided, but ball retrieval becomes difficult and time consuming
Solution Approach 1:
The device uses flexible fabric covers and elastic bands instead of rigid metal structures or heavy full covers. These flexible materials allow soccer balls to pass through easily during training, and the nets can be quickly collapsed and removed for rapid ball retrieval, eliminating the time-consuming extraction process required by rigid systems.
3Reliability
If conventional training devices (metal and/or full cover systems) are used, then training function is provided, but safety risks increase due to entanglement, distraction, and endangerment of goalkeeper
Solution Approach 1:
The device replaces rigid metal structures and heavy covers with flexible fabric nets and elastic bands. These soft, flexible materials eliminate entanglement hazards, reduce distractions for goalkeepers, and remove the danger of hard objects during training, while still providing effective training functionality.
4Reliability
If conventional training devices are used, then training function is provided, but device complexity and bulkiness increase
Solution Approach 1:
The complex training device is segmented into simple, modular components (spring bands, elastic bands, straps, stakes) that can be independently stored and transported. This segmentation reduces overall device complexity and bulkiness while maintaining full training functionality when components are assembled.
Solution Approach 2:
The essential training function is extracted from the bulky conventional device structure. The invention uses only the necessary minimal components (flexible bands and simple fasteners) to achieve the training goal, removing unnecessary complexity and bulk from the system.
5Reliability
If conventional training devices are used, then training function is provided, but cost increases
Solution Approach 1:
The device uses inexpensive, easily manufactured materials such as fabric, elastic bands, and simple plastic or metal fasteners. These components are far cheaper than conventional metal structures or heavy cover systems, reducing manufacturing cost while providing adequate training functionality.
Solution Approach 2:
The invention replaces expensive rigid metal structures and heavy materials with inexpensive flexible fabric and elastic materials. This material substitution dramatically reduces manufacturing costs while maintaining the essential training function through the flexible, adaptable nature of the components.
6Reliability
If conventional training devices with rigid configuration are used, then training function is provided, but adaptability decreases
Solution Approach 1:
The device uses dynamic, adjustable components including extender straps and detachable elastic bands that allow the training setup to be quickly reconfigured for different drill types, goal sizes, and training scenarios. This dynamic design provides high adaptability while maintaining reliable training function.
Solution Approach 2:
The modular components (spring bands, elastic bands, straps, stakes) can be assembled in multiple configurations to serve various training functions. The same set of components can create different goal sizes, field markers, or training setups, providing universal adaptability across multiple training scenarios.
