Rechargeable Plate Joiner Side-Mounted Battery Pack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rechargeable plate joiners face difficulties in easily attaching and detaching the battery pack when placed on a workbench, as the battery pack must be inserted from the rear and the device must be lifted upright, impairing operability and user-friendliness.
Innovation Solution
A rechargeable plate joiner design where the battery pack is slid and attached at a predetermined angle, preferably 90°, with its center of gravity aligned on the motor's axis line, allowing easy attachment and detachment even when the device is horizontal, and maintaining favorable balance and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery pack is inserted from the rear end of the motor housing, then the battery pack can be securely attached, but the attachment and detachment operations become difficult when the plate joiner is placed on a workbench
Solution Approach 1:
The patent inverts the traditional insertion direction by providing an insertion guide surface on the side face of the motor housing instead of the rear end. This allows the battery pack to be inserted from the side at a predetermined angle (preferably 90 degrees), making attachment and detachment operations easy even when the plate joiner is placed on a workbench, while maintaining secure attachment through the guide surface and engagement structure
2Ease of manufacture
If the plate joiner is lifted upright for battery pack insertion, then the battery pack can be attached, but the operability is impaired and the operation becomes inconvenient
Solution Approach 1:
Instead of requiring the plate joiner to be lifted upright for battery pack insertion, the patent provides an insertion guide surface on the side face of the motor housing. This allows the battery pack to be inserted from the side in any orientation, eliminating the need to lift the device upright and maintaining full operability during battery pack attachment and detachment operations
3Device complexity
If the battery pack is attached at the rear end, then the structure is simple, but the center of gravity balance is poor and the plate joiner cannot be maintained stably in vertical orientation
Solution Approach 1:
The patent changes the attachment location from the rear end (one-dimensional positioning) to the side face at a predetermined angle (introducing angular dimensionality). Specifically, the insertion guide surface is provided on the side face of the motor housing, allowing the battery pack to be attached at approximately 90 degrees to the longitudinal axis, which optimizes the center of gravity position and enables stable maintenance of the plate joiner in vertical orientation

AI summary
An attachment portion (22) of a battery pack (30) serving as a power supply is formed on a rear end of a motor housing (2) of a rechargeable plate joiner (1), and the battery pack (30) is slid and attached to the attachment portion (22) of the horizontally disposed motor housing (2) from above. In this state, a center of gravity position (G1) of the battery pack (30) is positioned on an axis line (L1) of an output shaft (4) of a motor (3).
