Instant Film Printer Alignment with a Single Repositionable Claw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers and digital cameras with a printer that accommodate instant film packs require a complex mechanism with multiple claw members to handle different film sizes, leading to increased component count and cost.
Innovation Solution
A printer and digital camera design that includes a loading room with a position alignment unit, allowing two types of instant film packs to be aligned and inserted at the same position, using a single claw member for discharge, and incorporating a transport mechanism and exposure head to handle both film types efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two claw members are provided at different positions to handle large and small instant film packs, then both film pack sizes can be accommodated, but the number of components increases and costs increase
Solution Approach 1:
A single claw member is designed to perform multiple functions by being repositioned. The claw member can be located at a first position to discharge large instant film packs and at a second position to discharge small instant film packs, eliminating the need for separate claw members for each film pack size.
Solution Approach 2:
The claw member is made movable between different positions rather than being fixed. The driving mechanism enables the claw member to switch between the first position (for large film packs) and the second position (for small film packs), allowing adaptive functionality without increasing component count.
2Device complexity
If a single claw member is used for both large and small instant film packs, then the number of components is reduced, but the claw member must be repositioned between different locations
Solution Approach 1:
The claw member is designed to be movable between a first position and a second position along the width direction of the loading room. A driving mechanism automatically repositions the claw member based on the type of instant film pack loaded, enabling a single component to serve multiple functions without manual intervention.
Solution Approach 2:
The single claw member is configured to discharge both large and small instant film packs by being repositioned to appropriate locations. When a large film pack is detected, the claw member moves to the first position; when a small film pack is detected, it moves to the second position, allowing one component to handle multiple film pack types.
3Device complexity
If the loading room is designed to accommodate only one film pack size, then the structure is simplified, but the printer cannot handle different instant film pack sizes
Solution Approach 1:
The claw member's position is dynamically adjusted based on the film pack size. The driving mechanism detects the type of instant film pack loaded into the loading room and automatically repositions the claw member to the appropriate location, allowing the loading room structure to remain simple while maintaining versatility.
Solution Approach 2:
The loading room is designed with a single claw member that serves multiple functions by being repositioned. This allows the loading room structure to remain simplified while the claw member adapts to discharge different film pack sizes (large or small) from the same loading space.

AI summary
A printer unit has a film pack room into which any one of a first instant film pack or a second instant film pack is loaded, an exposure head, and a controller. The second instant film pack is aligned in the film pack room so as to be shifted to the one side.
