Laser Marker Slideable Battery Pack Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser markers using non-rechargeable dry cells require frequent battery replacements, leading to resource waste and reduced freedom in arranging internal components due to the 'push-in' style of battery pack attachment, which increases the occupied space and limits the arrangement of elements.
Innovation Solution
A laser marker design featuring a slideable battery pack attachment portion that allows the battery pack to be positioned away from the center, reducing its space occupancy and maintaining the freedom of arrangement for internal components, while using a rechargeable battery pack to minimize resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery pack is attached by moving it in a direction perpendicular to the outer surface (push-in style), then the battery pack can be securely attached, but the region occupied by the battery pack becomes larger and the degree of freedom of arrangement of internal elements decreases
Solution Approach 1:
The patent changes the attachment direction from perpendicular to the outer surface (push-in style) to parallel to the outer surface (slideable style). This dimensional change allows the battery pack to be positioned at the end portion of the main body rather than occupying central space, thereby resolving the contradiction between secure attachment and arrangement freedom.
2Device complexity
If a non-rechargeable dry cell is used as power supply, then the device structure can be simpler, but resource waste increases due to frequent battery replacement
Solution Approach 1:
The patent implements a rechargeable battery pack that can be recharged and reused multiple times. Instead of discarding depleted dry cells, the battery pack recovers energy through recharging, significantly reducing battery waste while maintaining acceptable device complexity.
3Device complexity
If the battery pack is positioned centrally in the main body, then the attachment structure can be simpler, but the vertical dimension increases and the device may overturn
Solution Approach 1:
The patent positions the battery pack at the end portion of the main body rather than centrally, creating an asymmetric weight distribution. This asymmetric positioning lowers the center of gravity and improves overturn resistance, while the slideable attachment structure compensates for the increased structural complexity.
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 reduces resource waste by enabling reusable battery packs and maintains the degree of freedom for internal component arrangement, preventing increased vertical dimensions and potential overturning, while allowing for proper laser light projection.
