Luggage Case Retractable Placing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage cases with folding plates are prone to damage due to collisions and result in an oversized design when the folding plate is deployed, and objects placed on them are easily knocked off due to uneven surfaces.
Innovation Solution
A luggage case design featuring a pull rod assembly and a placing assembly with a rotatable plate and cup holders that retract into the case body when not in use, preventing damage and maintaining a compact size, and allowing stable placement of objects with the rotatable plate extending when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a folding plate is installed on the case body to place objects, then objects can be placed on the luggage case, but the overall size of the luggage case becomes too large
Solution Approach 1:
The placing assembly is nested within the first accommodating cavity of the case body when not in use, and can be extended outward when needed. This nesting approach allows the placing assembly to provide additional surface area for objects while maintaining a compact overall size when retracted into the cavity.
Solution Approach 2:
The placing assembly is designed to be movable between a retracted state (inside the first accommodating cavity) and an extended state (protruding from the case body). This dynamic configuration allows the luggage case to adapt its size and functionality based on user needs, providing versatility only when required.
2Adaptability or versatility
If a folding plate is installed on the case body to place objects, then objects can be placed on the luggage case, but the folding plate is prone to damage due to collision with external objects
Solution Approach 1:
The placing assembly can be retracted into the first accommodating cavity when not in use or when potential collision risks are anticipated. This preliminary protective action prevents the placing assembly from being exposed to external objects that could cause damage, thereby improving reliability.
Solution Approach 2:
The movable design of the placing assembly allows it to be dynamically positioned between protected (retracted) and functional (extended) states. This dynamic protection mechanism reduces the likelihood of collision damage by keeping the placing assembly inside the protective cavity when not actively needed.
3Quantity of substance
If objects are placed on the upper surface of the luggage case, then carrying capacity is increased, but an uneven upper surface causes objects to fall off easily
Solution Approach 1:
The placing assembly provides a dedicated local area with a flat, stable surface specifically designed for placing objects. This localized solution addresses the stability issue by creating a controlled environment for object placement, distinct from the uneven upper surface of the main case body.
Solution Approach 2:
The placing assembly can be extended to provide additional stable surface area when object placement is needed, and retracted when not needed. This dynamic adjustment allows the system to optimize both carrying capacity and object stability only when the placing assembly is in the extended position.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design prevents damage to the placing assembly from external collisions, maintains a compact case size, and ensures objects are placed stably without falling off, enhancing usability and durability.
Implementation Method 1
a rotatable plate rotatably connected to the fixing plate
Implementation Method 2
the pull rod assembly is telescopically connected to the case body; in a situation that the pull rod assembly is in a contracted state, the placing assembly enters the first accommodating cavity, and in a situation that the pull rod assembly is in an extended state, the placing assembly extends out of the first accommodating cavity

AI summary
A luggage case is provided, and the luggage case includes a case body, a pull rod assembly, and a placing assembly. The placing assembly includes a fixing plate fixedly connected to the pull rod assembly and a rotatable plate rotatably connected to the fixing plate. The case body is provided with a first accommodating cavity, and the pull rod assembly is telescopically connected to the case body; in a situation that the pull rod assembly contracts, the placing assembly enters the first accommodating cavity, and in a situation that the pull rod assembly extends, the placing assembly extends out of the first accommodating cavity. When the pull rod assembly contracts into the case body, the placing assembly is located in the first accommodating cavity, the luggage case is designed artistically, and the placing assembly does not contact with external objects to prevent the placing assembly from being damaged.
