Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card dealing machines often experience issues with card jamming, overlapping cards, and low efficiency due to poor card distribution mechanisms, which affect user experience.
Innovation Solution
A card dealing machine with a dual card distribution system using rollers and guide blocks to ensure smooth card passage, reducing overlapping and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single card distribution mechanism is used, then the device complexity is low, but the card distribution smoothness is poor and card overlapping occurs
Solution Approach 1:
The card distribution mechanism is divided into two independent distribution members (first and second card distribution members) that operate in sequence. The first card distribution member performs initial distribution, and the second card distribution member performs subsequent distribution, effectively segmenting the card distribution process to prevent overlapping and improve smoothness without requiring a single complex mechanism
2Productivity
If the card inlet height is set between one and two card thicknesses, then the card dealing machine can deal cards one by one, but card jamming and multiple cards being dealt occur
Solution Approach 1:
The first card distribution member performs preliminary distribution action on the cards before they reach the card inlet. By pre-distributing the cards in a controlled manner, the system ensures that cards are properly separated and positioned before entering the dealing mechanism, preventing jamming and ensuring accurate single-card dealing while maintaining high efficiency
3Duration of action of stationary object
If a single card distribution roller is used, then the device complexity is low, but friction and abrasion increase reducing machine lifespan
Solution Approach 1:
The single distribution roller is segmented into two separate distribution members (first and second card distribution members) that take turns contacting the cards. This segmentation reduces the friction and abrasion on any single component by distributing the mechanical stress across two members, thereby extending machine lifespan without requiring an overly complex single-component system
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 dual distribution system minimizes card overlap, enhances card distribution smoothness, and increases machine adaptability to different card thicknesses, reducing friction and abrasion, thus improving user experience and extending machine lifespan.
Implementation Method 1
