Flat Tool Bottle Opener Deposit Coin Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat tools with bottle opener functionality are not optimized for compactness and versatility, with openings often being too large for efficient use as both deposit coins and bottle openers, and lack integrated features for additional functions like cutting or attachment to key rings.
Innovation Solution
A flat tool design with a circular edge surrounding a smaller bottle opener opening, integrated pivotable tools for versatility, and additional features such as a cutting tool insert and key ring attachment, made from a durable steel base body with specific dimensions and features like wave-shaped tongues and snap hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening width is made larger to accommodate beverage capsules, then the bottle opening function is improved, but the tool cannot be used as a deposit coin
Solution Approach 1:
The patent applies local quality by creating a precisely sized opening (18-22mm) that is smaller than the beverage capsule diameter (30mm) but larger than standard deposit coins (23-26mm). This localized dimensional optimization allows the opening to accommodate the capsule while maintaining compatibility with deposit coin dimensions, resolving the contradiction between bottle opening functionality and deposit coin usability.
2Adaptability or versatility
If the tool includes multiple integrated functions (bottle opener, deposit coin, cutting tool), then versatility is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated tool body. The bottle opener opening, deposit coin area, cutting tool blade, and snap hook are all combined in one flat tool structure. This consolidation achieves versatility while minimizing complexity by eliminating the need for separate tools for each function.
Solution Approach 2:
The tool is designed with universal multi-functionality, where the same flat tool structure serves as a bottle opener, deposit coin, cutting tool, and key attachment. The standardized dimensions and integrated features allow one tool to replace multiple specialized tools, achieving versatility without proportionally increasing complexity.
3Volume of moving object
If the opening is made smaller for compactness, then the tool size is reduced, but the bottle opening capability is compromised
Solution Approach 1:
The patent optimizes the opening dimension parameter to a specific range (18-22mm) that balances compactness with functionality. This parameter optimization allows the opening to be small enough for a compact tool design while remaining large enough to accommodate the beverage capsule (30mm diameter) and provide adequate leverage for opening.
