Counterweighted Sofa Caddy for Secure Chair-Arm Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a storage solution that can securely and removably attach to a chair to store domestic articles, providing a convenient and organized way to carry personal items without compromising the chair's structure or functionality.
Innovation Solution
The sofa caddy, comprising a base sheeting with attached pockets and a counterweight, drapes over the chair's manchette, using the counterweight to secure it in place between the cushion and manchette, allowing for storage of domestic articles while maintaining the chair's usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage apparatus is attached to a chair, then storage functionality is improved, but the chair's structure and functionality may be compromised
Solution Approach 1:
The storage apparatus is segmented into separate functional components: a base sheeting for attachment, multiple pockets for different types of articles, and a counterweight mechanism for securing. This segmentation allows the storage function to be added without modifying the chair's core structure, maintaining structural integrity while providing versatile storage capability.
Solution Approach 2:
The base sheeting acts as an intermediary element between the chair and the storage pockets. It drapes over the chair's manchette and provides attachment points for the pockets and counterweight, serving as a mediator that connects the storage components to the chair without requiring direct modification to the chair's structure.
2Reliability
If a storage apparatus is securely attached to a chair, then storage reliability is improved, but ease of attachment and detachment may be worsened
Solution Approach 1:
A counterweight mechanism is incorporated into the base sheeting that uses gravity and friction to secure the storage apparatus to the chair. The counterweight creates a balancing force that holds the pockets in place against the chair's manchette, providing reliable attachment without requiring complex fastening mechanisms, thus maintaining ease of installation and removal.
3Quantity of substance
If multiple pockets are added to store domestic articles, then storage capacity is improved, but device complexity increases
Solution Approach 1:
The base sheeting serves multiple functions simultaneously: it provides the attachment surface for the pockets, acts as the structural support for the counterweight mechanism, and drapes over the chair's manchette to secure the entire assembly. This multi-functionality reduces the need for additional separate components, thereby increasing storage capacity without proportionally increasing overall device complexity.

AI summary
The sofa caddy is a storage apparatus. The sofa caddy is configured for use with a chair. The chair is further defined with a manchette, a bench, and a cushion. The bench is a horizontal support surface formed by the chair. The cushion is a padding structure that: 1) rests on the bench; and 2) is placed against the manchette. The manchette is a vertical structure that prevents the cushion from sliding off of the bench. The sofa caddy removably attaches to the chair. The sofa caddy comprises a base sheeting, a plurality of pockets, and a counterweight. The plurality of pockets and the counterweight attach to the base sheeting. The counterweight inserts between the cushion and the manchette to secure the soda caddy to the chair. The base sheeting drapes over the manchette of the chair. The plurality of pockets store the one or more domestic articles.
