Portable Printer Attaching Adapter for Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable printers that use external power sources do not effectively utilize the battery storage space for attachment to targets, such as vehicles or buildings, lacking a convenient method to attach the printer securely.
Innovation Solution
A portable printer design that includes a housing with an attachment/detachment recess for a battery unit, allowing the battery unit to be replaced with an attaching adapter of similar shape, which provides attachment portions for secure attachment to targets using threaded holes, enabling easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery storage space is utilized for attachment, then the ease of attachment is improved, but the battery drive function is lost
Solution Approach 1:
The attachment/detachment recess is designed to dynamically switch between two functions: holding the battery unit for portable operation or receiving the attaching adapter for fixed installation. This dynamic reconfigurability allows the same structural space to serve different purposes based on user needs, resolving the contradiction between attachment capability and battery functionality.
Solution Approach 2:
The attachment/detachment recess serves multiple functions: it acts as a battery storage compartment when the battery unit is installed, and as an attachment interface when the attaching adapter is installed. This multi-functionality allows the printer to adapt between portable and fixed installation modes without requiring separate structural elements, thereby maintaining versatility while enabling easy attachment.
2Stability of the object's composition
If the attaching adapter is used instead of the battery unit, then the attachment stability is improved, but the portability is reduced
Solution Approach 1:
The system is segmented into three independent components: the printer main body, the battery unit, and the attaching adapter. This segmentation allows users to selectively install only what is needed for the current situation - either the battery unit for portable use or the attaching adapter for stable fixed installation - without being constrained by a fixed design. The modular approach resolves the contradiction by enabling flexible configuration based on portability versus stability requirements.

AI summary
The disclosure discloses a portable printer including a printer main body and an attaching adapter. The printer main body includes a platen roller, a thermal line head, and a housing. The platen roller is configured to feed a sheet to be printed. The thermal line head is configured to form print on the sheet to be printed fed by the platen roller. The housing encompasses the platen roller and the thermal line head and includes an attachment/detachment recess configured to attach or detach a battery unit for driving the platen roller and the thermal line head. The attaching adapter has an outer shape substantially the same as an outer shape of the battery unit, is configured to be attached to the attachment/detachment recess of the printer main body, and includes an attachment portion for attaching the printer main body to an attachment target.
