Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag holders are not designed for easy assembly and disassembly, are prone to contamination, and require multiple people to fill bags, while also lacking expandability and ease of use.
Innovation Solution
A novel bag holding device with U-shaped supports and adjustable arms that can be repeatedly assembled and disassembled, preventing contamination and allowing single-person operation, with optional cushioned tips to protect the bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing bag holders are used, then bags can be held during filling, but the holders are not designed for easy assembly and disassembly, are prone to contamination, and require multiple people to fill bags
Solution Approach 1:
The bag holder is divided into multiple detachable legs that can be easily assembled and disassembled. Each leg is a separate component that connects to a central body, allowing the device to be taken apart for cleaning and storage, directly addressing the need for easy assembly and disassembly while maintaining simplicity
Solution Approach 2:
The bag holder incorporates adjustable legs that can be positioned at different angles and heights. This dynamic adjustability allows the device to adapt to different bag sizes and filling operations, improving ease of operation while the adjustable mechanism remains mechanically simple
2Ease of operation
If existing bag holders are used, then bags can be held during filling, but the holders are prone to contamination of the sealing area
Solution Approach 1:
The detachable leg design allows the sealing area to be separated from potential contamination sources. The legs can be removed and washed separately, preventing cross-contamination and making hygiene maintenance simple and effective
Solution Approach 2:
The sealing area is extracted as a distinct, accessible component that can be easily cleaned and sanitized. The design separates the sealing surface from the structural support elements, allowing targeted cleaning of the sealing area without disassembling the entire device
3Productivity
If existing bag holders are used, then bags can be held during filling, but multiple people are required to fill bags
Solution Approach 1:
The bag holder integrates multiple functions into a single device: holding the bag open, supporting the bag weight, and positioning the sealing area. This consolidation of functions into one stable structure allows a single person to perform all filling operations independently
Solution Approach 2:
The bag holder is designed to maintain bag position and stability automatically without requiring additional hands or people. The adjustable legs and sealing mechanism work together to hold the bag in the correct position throughout the filling process, enabling single-person operation while maintaining ease of use
4Adaptability or versatility
If the device is made expandable for different bag sizes, then versatility is improved, but device complexity increases
Solution Approach 1:
The adjustable legs can be positioned at various angles and heights to accommodate different bag sizes and shapes. This dynamic adjustability provides versatility without requiring multiple fixed-structure devices, and the adjustment mechanism remains mechanically simple
Solution Approach 2:
The bag holder is designed as a universal device that can handle various bag types and sizes through its adjustable configuration. The same basic structure serves multiple functions for different applications, avoiding the need for complex specialized mechanisms for each bag type
