Trolley Case Pull Rod Charging Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trolley cases lack a convenient and secure method for carrying and using external charging devices, leading to inefficiencies in charging electronic equipment during travel, as charging devices like Charge Pal must be removed and handled separately, wasting time and being inconvenient during inspections.
Innovation Solution
A trolley case design featuring a pull rod frame with a telescopic pull rod and a charger accommodating cavity, equipped with a sliding cover, elastic lugs, and buffer foam, allowing for easy access and secure storage of charging devices, along with a self-moving mechanism and integrated charging port, pressure sensor, and GPS module for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging device is placed in the trunk of the trolley case, then the charging device can be stored, but it requires removing the charging device from the trunk to charge, resulting in time loss and inconvenience
Solution Approach 1:
The charging device is integrated into the pull rod frame, merging the charging function with the trolley case structure. The charging cavity is built into the pull rod frame, allowing the charging device to be permanently mounted and easily accessible without removal from storage.
Solution Approach 2:
The charging device is pre-positioned in the pull rod frame in a ready-to-use state. The sliding cover is pre-arranged to provide quick access, and the spring mechanism is pre-loaded to automatically present the charging device when needed, eliminating the need for retrieval actions.
2Reliability
If the charging device is stored in the trunk, then storage capacity is utilized, but the charging device may fall out or be misplaced during inspection
Solution Approach 1:
The sliding cover mechanism allows the charging cavity to dynamically transition between closed and open states. The spring-loaded design enables the charging device to be automatically presented when the sliding cover is moved, providing both security when closed and easy access when needed.
Solution Approach 2:
The sliding cover acts as an intermediary between the charging device and the external environment. It provides a controlled interface that maintains security while enabling authorized access, and the spring mechanism serves as an intermediary force that automatically presents the charging device.
3Adaptability or versatility
If a fixed charging cavity is used, then the structure is simple, but it cannot adapt to charging devices of various specifications
Solution Approach 1:
The spring-loaded charging device creates a dynamic system that automatically adjusts to different charging device sizes. The spring force adapts to the inserted device, providing secure holding for various specifications without requiring multiple fixed configurations or complex adjustment mechanisms.
