Shouldering Power Supply Cord Direction Change Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shouldering type power supply devices require the use of tools to change the direction of the power cord, making the process burdensome and inefficient.
Innovation Solution
A shouldering type power supply device design that allows for easy direction change of the power cord without tools, featuring a battery case with guide parts and a carrier with a cover structure that includes an elastic upper cover to protect the terminal case and power cord, enabling the power cord to be easily redirected between guide parts and the case body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery case is fixed on the carrier with screws, then the battery case is securely attached, but the power cord direction cannot be changed easily without tools
Solution Approach 1:
The cover structure is divided into a fixed lower cover and a removable upper cover. The upper cover can be detached to allow power cord direction changes, while the lower cover remains fixed to maintain structural stability. This segmentation allows easy reconfiguration without affecting the overall secure attachment of the battery case to the carrier.
Solution Approach 2:
The cover structure transitions from a completely fixed design to a partially movable design. The upper cover is designed to be removable, enabling dynamic reconfiguration of the power cord direction. This dynamic element allows the structure to adapt between a secure fixed state during operation and an accessible open state for reconfiguration.
2Ease of operation
If the battery case is made accessible for power cord reconfiguration, then the power cord direction can be changed easily, but the terminal case and power cord are exposed to damage risk
Solution Approach 1:
The cover structure is segmented into two parts: the lower cover that remains fixed to protect the terminal case and power cord connections, and the upper cover that can be removed to allow power cord direction changes. This segmentation enables selective access - only the necessary upper portion is opened while the sensitive lower portion remains protected.
Solution Approach 2:
The lower cover acts as an intermediary protective barrier that remains in place during power cord reconfiguration. It mediates between the need for access (upper cover removal) and the need for protection (lower cover remaining fixed), allowing the power cord to be reconfigured while the terminal case remains shielded.
3Reliability
If a tool is used to screw and unscrew the screws on the battery case, then the battery case can be securely attached and detached, but the operation becomes burdensome and time-consuming
Solution Approach 1:
The upper cover is extracted as a separate removable component from the fixed lower cover. This extraction allows the power cord access function to be separated from the secure attachment function. The lower cover with screws remains fixed to maintain reliable attachment, while the upper cover can be quickly removed and reattached without tools for power cord reconfiguration.
Solution Approach 2:
The cover structure introduces dynamic elements through the removable upper cover, contrasting with the static fixed lower cover. This dynamic design allows quick reconfiguration of the power cord direction without the time-consuming process of unscrewing and rescrewing, while the fixed lower cover maintains reliable attachment security.

AI summary
A shouldering type power supply device is provided in which a direction of a power cord drawn out from a battery case is easily changed, without using a tool. The shouldering type power device (1) has a battery case (10) that is mounted with a battery and a carrier (50) to which the battery case is detachably attached. The battery case (10) has a case body (20) that houses the battery and a terminal case (30) that is attached on a top surface (20c) of the case body (20). The terminal case (30) has a cord hole (31) on a surface thereof, and has right and left guide parts (32) protruding on both right and left sides of the cord hole (31). A power cord (40) is inserted through the cord hole (31) and is held between one of the guide part (32) and the top surface (20c) of the case body (20).
