Vacuum Packaging Machine Sub-Controller One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum packaging machines have complex and inconvenient operation processes, requiring users to manually stabilize the bag mouth and control multiple functions with separate hands, leading to potential air leakage and suboptimal heat-sealing.
Innovation Solution
A vacuum packaging machine design featuring a sub-controller on the vacuum cover with function keys for one-handed operation, allowing simultaneous closure of the vacuum cover and activation of vacuuming and heat-sealing processes, with the main controller on the machine body connected to the vacuumizing and heat-sealing units, and a handle for easy bag stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller is provided on the machine body separated from the vacuum cover, then the control structure is stable, but the operation becomes inconvenient and tedious
Solution Approach 1:
The controller is divided into two parts: a main controller (101) on the machine body for stable control, and a sub-controller (106) on the vacuum cover for convenient operation. The sub-controller includes function keys that communicate with the main controller via wireless or wired connection, allowing users to operate the vacuum cover and control functions simultaneously with one hand.
2Manufacturing precision
If the user manually stabilizes the bag mouth with hands, then the heat-sealing effect can be improved, but the operation process becomes complicated and tedious
Solution Approach 1:
The vacuum cover (103) is designed with self-service functionality where the act of closing the vacuum cover automatically stabilizes the bag mouth (105) through the integrated sub-controller and positioning structure. This eliminates the need for users to manually hold and stabilize the bag mouth with their hands, as the system's structure and control mechanism work together to maintain proper positioning automatically during the vacuum and heat-sealing process.
3Reliability
If the lock structure is operated with both hands, then the vacuum chamber sealing is ensured, but the overall operation time increases
Solution Approach 1:
The locking function and control function are merged into a single integrated sub-controller (106) on the vacuum cover. This allows the user to lock the vacuum cover and activate vacuum/heat-sealing functions simultaneously with one hand operation, eliminating the sequential two-handed operation required by traditional designs and reducing overall operation time while maintaining sealing reliability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the operation by enabling one-handed control of the vacuum cover closure and function key activation, ensuring better heat-sealing and reducing the risk of air leakage, resulting in a more efficient and user-friendly packaging process.
