Packaging Assembly for Printer Consumable Resetting and Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processes for resetting and detecting consumables in printers are cumbersome and inefficient, requiring multiple steps and potential contamination of the chip during the manufacturing process.
Innovation Solution
A packaging assembly that includes an outer packaging unit and a loading unit to securely accommodate and limit the movement of consumables, with an installing unit that fixes the consumable in place, allowing for efficient resetting and detection without the need for frequent disassembly and assembly, and includes a buffer member to prevent damage and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the consumable is manually installed on the resetter and detector separately for resetting and detection, then the chip can be accessed for operations, but the process becomes cumbersome and inefficient with repeated installation and removal steps
Solution Approach 1:
The patent combines the resetter and detector into a single integrated device that can perform both resetting and detection operations. The consumable is installed once on this integrated device, which contains both reset contacts and detection sensors, eliminating the need for separate installation and removal steps that occur when using separate resetter and detector devices.
Solution Approach 2:
The patent implements preliminary positioning structures including guide rails, positioning grooves, and clamping mechanisms that automatically align and secure the consumable in the correct position before operations begin. This preliminary action eliminates the need for manual adjustment and ensures proper contact between the chip terminals and both the reset contacts and detection sensors from the start.
2Reliability
If the consumable is handled multiple times during resetting and detection processes, then operations can be completed, but the chip is at risk of contamination
Solution Approach 1:
The integrated device combines resetting and detection functions in one unit, allowing both operations to be performed without removing the consumable. The chip remains in a controlled environment throughout the process, exposed only when necessary for the integrated operations, thereby reducing contamination risk while maintaining operational efficiency.
Solution Approach 2:
The patent introduces a protective cover or shield that can be opened only when the consumable is properly positioned in the integrated device. This intermediary structure prevents contamination by limiting exposure of the chip to the external environment, while still allowing access when needed for the combined resetting and detection operations.
3Stability of the object's composition
If the consumable is securely fixed during operations, then positioning stability is improved, but the device structure becomes more complex
Solution Approach 1:
The fixing mechanism is divided into separate functional modules: guide rails for alignment, positioning grooves for lateral securing, and independent clamping mechanisms for vertical fixation. Each module performs a specific function, allowing the consumable to be securely fixed in multiple dimensions without requiring a single complex fixing structure.
Solution Approach 2:
The patent implements self-aligning and self-locking features where the consumable's own structure (such as its shape or built-in features) works together with the positioning grooves and clamps to achieve secure fixation. The design allows the consumable to guide its own positioning and the fixing mechanism to automatically engage without requiring complex external control systems.
