Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body-worn carriers for window cleaning accessories are often bulky, expensive, lack versatility in accommodating different tools, and fail to securely hold items while allowing for convenient and swift removal.
Innovation Solution
A modular caddy with an attachment system that allows quick mounting of various modular carrier units to a main bag, enabling the units to be attached to each other, thus providing a versatile and secure way to carry window cleaning accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional body-worn carriers are used to carry window cleaning accessories, then items can be carried on the body, but the carriers are bulky and lack versatility in accommodating different tools
Solution Approach 1:
The carrier system is divided into a main bag and multiple detachable modular units. Each modular unit can be independently attached or removed from the main bag, allowing the user to configure the system according to specific tool requirements. This segmentation enables versatility without requiring the entire system to be bulky at all times.
Solution Approach 2:
The main bag is designed with universal attachment features (strips of webbing with gaps) that can accommodate various types of modular units. The modular units are designed with standardized attachment means that correspond to these gaps, creating a universal interface. This allows different tools and accessories to be carried using the same base structure, achieving multi-functionality without increasing overall bulk.
2Ease of operation
If traditional carriers are designed to securely hold items, then items are held securely, but items cannot be conveniently and swiftly removed
Solution Approach 1:
The attachment system transitions between two dynamic states: a secured state where the attachment means engage with the webbing gaps to hold items securely, and a released state where the attachment means can be quickly disengaged for convenient removal. This dynamic design allows the same mechanism to provide both security during transport and ease of access when needed.
Solution Approach 2:
The attachment means act as an intermediary mechanism between the modular units and the main bag. These attachment means provide a standardized interface that enables both secure connection and quick release, mediating between the conflicting requirements of security and convenience. The attachment means can be easily engaged and disengaged while maintaining reliable holding when connected.
3Productivity
If multiple squeegees and extension poles are carried to avoid descending for tools, then efficiency is enhanced, but the equipment occupies limited space and contributes to bulkiness
Solution Approach 1:
Large items like squeegees and extension poles are separated into individual modular units that can be attached to the main bag. This segmentation allows these items to be distributed around the user's body rather than occupying continuous space on the platform, reducing the concentrated bulk while maintaining accessibility.
Solution Approach 2:
The carrier system utilizes the vertical dimension by hanging from the waistbelt, transforming the storage problem from a horizontal space constraint on the platform to a vertical suspension system. This allows tools to be carried close to the user's body in three-dimensional space rather than occupying flat platform space, improving productivity without increasing platform footprint.

AI summary
A modular caddy for carrying window cleaning accessories includes a main bag and at least one modular unit attachable to the main bag. The main bag has a back panel and a cover sheet, with securing means arranged on the back panel for releasably securing the main bag to a garment. Strips of webbing are arranged on the outer surface and fixed at regular intervals to form a series of gaps. Attachment means are dimensioned to correspond to said gaps and configured for releasably attaching modular units to the strips of webbing.The modular units also have strips of webbing for attaching to the main bag and for mounting further modular units thereon.
