Hinged-Lid Training Suitcase With Flat Screen for On-Field Tactics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for showing videos during tactical discussions in sports, such as football, are cumbersome and often hinder immediate knowledge transfer due to the use of laptops or tablets, which are difficult to see and handle, and post-session analysis compromises immediacy.
Innovation Solution
A robust suitcase-like training tool with a hinged lid and base, accommodating a flat screen and a tactics board, equipped with sun visors and adjustable angle, allowing on-site video presentation and tactical discussions directly on the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a laptop or tablet is used to show videos during tactical discussions, then media content can be displayed, but the device is difficult for players to see and handle
Solution Approach 1:
The system separates the display function from the handling function by using a dedicated flat screen mounted on a stable stand, while the coach uses a separate control device (laptop/tablet) to operate it. This segmentation allows the screen to be positioned optimally for visibility while the control device remains portable and easy to handle.
Solution Approach 2:
The flat screen on the stand acts as an intermediary between the control device and the players. Instead of players directly interacting with a portable device, they view content on the larger, fixed screen which serves as a mediator for information delivery, improving visibility while the control device remains separate and easy to operate.
2Reliability
If a laptop or tablet is used for video presentation, then media content can be displayed, but the device suffers due to careless handling
Solution Approach 1:
The system divides the functional requirements: the flat screen on the stable stand handles the display function and is protected from handling damage, while the control device (laptop/tablet) remains separate and portable. This segmentation protects the display component from careless handling while maintaining operational convenience.
Solution Approach 2:
The flat screen mounted on a stable stand serves as a protected intermediary for displaying content. The stable mounting protects the screen from damage due to careless handling, while the separate control device maintains ease of operation. The intermediary structure inherently protects against handling-related damage.
3Loss of time
If video analysis is conducted after the training session in a clubhouse or conference room, then detailed analysis can be performed, but the immediacy of knowledge transfer is compromised
Solution Approach 1:
The system prepares all necessary equipment (flat screen, stand, control device, media content) in advance and assembles it on the field before the training session. This preliminary preparation enables immediate video analysis during the session without time delay, while the modular design keeps operational complexity manageable.
Solution Approach 2:
The system transitions from post-session analysis in a different location (clubhouse) to on-field analysis during the training session. By adding the spatial dimension of moving the analysis equipment to the field, the system eliminates time delay while the modular, self-contained design keeps operational complexity manageable.
4Illumination intensity
If a flat screen is mounted on a stable stand for on-field use, then visibility and immediacy are improved, but the device becomes more complex and harder to transport
Solution Approach 1:
The stable stand system is designed to be universally applicable to various training scenarios and can accommodate different flat screen sizes. The modular design allows the same stand structure to support different configurations, reducing overall system complexity while maintaining high visibility capabilities.
Solution Approach 2:
The flat screen is nested within or mounted on the stable stand structure, creating a compact integrated unit. This nesting approach reduces the overall footprint and simplifies transport compared to separate components, while maintaining the stability and visibility benefits of the mounted display.
