Chair Runner Attachment for Secure Multi-Direction Rocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for converting stationary chairs into rocking chairs are not adaptable to different-sized chairs, are complex and expensive, difficult to attach and remove, bulky, limited to front-to-rear rocking, and do not adequately secure the chair runners with a high slope.
Innovation Solution
A chair runner system with recessed portions for leg reception and an arcuate design for rocking, along with a simple attachment mechanism like elastic cords or hooks, allowing for easy installation and removal, compact storage, and secure attachment to permit both front-to-rear and side-to-side rocking with a lower slope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional apparatuses and methods are used to convert stationary chairs into rocking chairs, then the chair runners can be secured to the chair, but the apparatus is undesirably complex, expensive, and difficult to attach to and remove from a chair
Solution Approach 1:
The conversion system is divided into separate modular components: chair runners with recessed portions for leg reception, and separate attachment means (such as straps or fasteners). This segmentation allows each component to be simple and easy to manufacture, while collectively providing reliable securing. The runners can be independently attached to chair legs without requiring a complex integrated apparatus.
Solution Approach 2:
The chair runners are designed with universal applicability through adjustable attachment means that can accommodate different chair sizes and leg configurations. The recessed portions can receive various leg types, and the attachment mechanism can be adjusted or repositioned, allowing the same runner design to work across multiple chair types without requiring complex customization.
2Reliability
If conventional apparatuses and methods are used to convert stationary chairs into rocking chairs, then the chair runners can be secured to the chair, but the apparatus is difficult to attach to and remove from a chair
Solution Approach 1:
The attachment means incorporates dynamic, reversible fastening mechanisms such as adjustable straps, buckles, or snap-fasteners that can be easily engaged and disengaged. This allows the chair runners to be securely attached when needed but also easily removed when not needed, providing both reliable securing and operational ease without compromise.
Solution Approach 2:
The attachment system is designed to be self-servicing, allowing users to attach and remove the chair runners without requiring tools or complex procedures. The recessed portions guide the chair legs into place, and the attachment means (such as straps with buckles) can be easily fastened and unfastened by hand, enabling simple user-operated installation and removal.
3Reliability
If conventional apparatuses and methods are used to convert stationary chairs into rocking chairs, then the chair runners can be secured to the chair, but the apparatus is undesirably bulky and difficult to transport and store
Solution Approach 1:
By segmenting the conversion system into separate chair runners and attachment means, each component can be compact and lightweight. The runners are thin profiles that attach to chair legs, and the attachment means can be stored separately or integrated into the runner design, eliminating the need for bulky apparatus structures and making the components easy to transport and store.
Solution Approach 2:
The attachment means can be nested within or integrated into the chair runner structure when not in use. For example, straps can be wrapped around or stored within the runner body, and fasteners can be recessed into the runner housing, allowing the entire conversion system to collapse into a compact form for easy storage and transport while maintaining full functionality when deployed.
4Reliability
If conventional apparatuses and methods are used to convert stationary chairs into rocking chairs, then the chair runners can be secured to the chair, but the apparatus is undesirably limited to front-to-rear rocking
Solution Approach 1:
The chair runners are designed with asymmetric attachment points or adjustable positioning capabilities that allow the runner to be oriented at different angles relative to the chair legs. This asymmetry enables the runners to accommodate both front-to-rear rocking (traditional orientation) and side-to-side rocking (rotated orientation), providing versatility in rocking direction while maintaining secure attachment through the same basic securing mechanism.

AI summary
A chair runner having a first end and a second end and comprising a first side having a first recessed portion and a second recessed portion, a second side that is substantially arcuate and an attachment means. The first recessed portion is disposed adjacent to the first end and the second recessed portion is disposed adjacent to the second end, the first recessed portion is adapted to removably receive a first leg of a stationary chair and the second recessed portion is adapted to removably receive a second leg of the stationary chair, and the attachment means is adapted to removably secure the chair runner to the stationary chair. A method for converting a stationary chair having at least four legs into a rocking chair comprising removably attaching each of the at least one pair of chair runners to two legs of the stationary chair.
