Stretch Film Dispenser With Telescopic Rod And Roller Moving Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stretch film dispensers are cumbersome and laborious to move, especially when wrapping articles at lower positions, leading to strain on the user's waist and hands due to their weight and lack of mobility features.
Innovation Solution
A stretch film dispenser equipped with a moving device, featuring a telescopic rod and moving unit with rollers, allowing for easy and convenient movement by adjusting the telescopic rod to a suitable height for holding and using the rollers to facilitate movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stretch film dispenser is equipped with a film roll and structure for wrapping, then the packaging function is achieved, but the device becomes heavy and difficult to move
Solution Approach 1:
The patent applies the dynamics principle by incorporating a telescopic rod that can extend and retract, allowing the dispenser to adapt its height and position dynamically. This enables the user to adjust the dispenser to comfortable working heights, reducing strain when moving and operating the device, thereby improving ease of movement despite the device's weight.
Solution Approach 2:
The telescopic rod acts as an intermediary element between the user and the heavy dispenser body. By providing an extendable handle, it mediates the interaction, allowing users to leverage their body weight and apply force more effectively when moving the dispenser, thus reducing the perceived effort required to move the heavy device.
2Productivity
If the user holds the stretch film dispenser with both hands to wrap articles quickly, then packaging efficiency is improved, but user strain on waist and hands increases
Solution Approach 1:
The telescopic rod provides dynamic height adjustment, allowing users to position the dispenser at ergonomically optimal heights for different tasks. This reduces waist strain by eliminating the need to bend over for low articles and hand strain by allowing the dispenser to be positioned at comfortable handling heights, thereby maintaining high packaging efficiency without excessive strain.
Solution Approach 2:
The patent changes the height parameter of the dispenser through the telescopic rod mechanism. By adjusting the rod extension, the dispenser can be positioned at various heights to match the user's ergonomics and the article being wrapped, reducing physical strain while maintaining packaging speed and efficiency.
3Adaptability or versatility
If the telescopic rod is extended to increase height adjustability, then adaptability to different positions is improved, but device complexity increases
Solution Approach 1:
The telescopic rod implements dynamics by providing a simple extendable-retractable mechanism that enables height adjustment. This dynamic structure allows the dispenser to adapt to different working heights and positions without requiring complex multi-component adjustment systems, thereby achieving good adaptability with minimal added complexity.
Solution Approach 2:
The telescopic rod serves multiple functions: it increases height adjustability for different articles, provides an extended handle for easier moving, and offers structural support. This multi-functionality achieves high adaptability without proportionally increasing complexity, as a single mechanism accomplishes multiple objectives.
