Convertible Bag Hinge Mechanism for Stable Cricket Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cricket equipment transport bags are not ergonomically designed for relaxed back transport due to the need to accommodate a base, which requires significant bag dimensions.
Innovation Solution
A transport bag with two structural panels that can be transformed from a portage configuration into a stable configuration, allowing it to serve as a cricket base without the need for additional accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bag is designed to carry a cricket base, then the base can be transported, but the bag size becomes large and uncomfortable for back carrying
Solution Approach 1:
The bag is designed to perform multiple functions: it can carry cricket equipment in its portable configuration and transform into a stable base structure when needed. The rear panel with hinge mechanism serves both as a carrying component and as a support structure that can be deployed to form a stable base, eliminating the need for a separate dedicated base-carrying bag.
Solution Approach 2:
The bag incorporates dynamic elements including a hinge mechanism that allows the rear panel to transition between different configurations. The panel can be folded at various angles to adapt between a compact carrying state and an extended stable base state, enabling the bag to dynamically adjust its form based on functional requirements.
2Adaptability or versatility
If the bag is made larger to accommodate a base, then base transport is enabled, but ergonomic comfort for back carrying deteriorates
Solution Approach 1:
The bag is segmented into distinct functional panels including a front panel, rear panel, and bottom panel that can be independently positioned. The rear panel is further divided into sections connected by hinges, allowing selective deployment of the base-supporting portions while keeping the carrying portion compact and ergonomic.
Solution Approach 2:
The bag transitions from a static carrying bag to a dynamic structure that can be reconfigured. The hinge mechanism enables the rear panel to be deployed at specific angles to create a stable base while maintaining a compact form for comfortable carrying, adapting the bag's configuration to the immediate functional need.
3Adaptability or versatility
If the bag transforms from carrying configuration to stable configuration, then it forms a cricket base, but the transformation mechanism adds structural complexity
Solution Approach 1:
The transformation mechanism utilizes simple hinge joints that allow panels to be folded and locked into different configurations. The hinge system provides inherent mechanical advantage, allowing the panel to be easily positioned at different angles without requiring complex locking mechanisms or multiple fastening points.
Solution Approach 2:
The bag panels are designed with flexible yet structurally sufficient materials that can be easily folded and positioned. The panels maintain their shape when deployed to form the stable base while remaining flexible enough to be conveniently stored in the compact carrying configuration, reducing the need for rigid structural elements.
4Stability of the object's composition
If the lower panel is placed in abutment on support, then the bag becomes stably erected, but the panel must be inclined which requires foldable hinge mechanism
Solution Approach 1:
The hinge mechanism enables the rear panel to be dynamically positioned at an inclined angle relative to the front panel, allowing the lower panel to rest stably on the ground support. The hinge provides the necessary degrees of freedom for the panel to achieve the optimal inclination angle for stability while maintaining a simple mechanical connection.
Solution Approach 2:
The hinge mechanism is integrated directly into the panel construction, merging the connection function with the structural element itself. This eliminates the need for separate external hinges or complex joining mechanisms, as the hinge is built into the panel assembly during manufacturing.

AI summary
The invention relates to a bag formed of two structural panels, respectively front (5) and rear (6), having first means (7) for reversible association in a configuration forming between them a shell delimiting an internal carrying compartment, the rear panel (6) having two sides, respectively upper (6s) and lower (6i), which are connected by a folding hinge (13) arranged to allow the relative arrangement of said sides between an aligned position for forming the shell and an inclined position, the upper side (6s) and the front panel (5) having second means (14) for reversible association in a configuration in which the sides (6s, 6i) are held in an inclined position with the front panel (5) in an upright position, the inclined lower side (6i) being arranged to be able to rest on a support in order to transform the bag (1) into a front panel (5) which is stably upright on said support.
