Chair Back Strap Assembly with Adjustable Themed Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for chair decorations that can be easily attached and adjusted to fit various chair types and sizes, allowing users to personalize their seating with themed elements that can be optionally removable.
Innovation Solution
A themed assembly for a chair comprising a strap that securely fits around the chair back, with a themed element attached to the strap, using mechanisms like hook-and-loop fasteners, snaps, or buckles to ensure adjustability and removability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a strap is used to surround the chair back, then the assembly can be easily attached and adjusted to fit various chair types and sizes, but the themed element may become detached or unstable
Solution Approach 1:
The themed element is nested within a holder that is itself attached to the strap. The holder contains the themed element securely, creating a nested structure where the strap provides adaptability to different chairs while the holder ensures stability of the themed element.
Solution Approach 2:
The assembly is divided into separate functional components: the strap for attachment and adjustment to various chairs, the holder for securing the themed element, and the themed element itself. This segmentation allows each component to optimize its specific function - the strap provides versatility while the holder provides stability.
2Reliability
If the themed element is permanently attached to the chair, then it provides stable decoration, but it cannot be easily removed or adjusted
Solution Approach 1:
The attachment mechanism is designed to be dynamic rather than static. The strap can be adjusted to different positions and tightened to different degrees, and the holder allows the themed element to be attached and detached as needed. This provides both stability when attached and ease of removal when needed.
Solution Approach 2:
The holder acts as an intermediary between the strap and the themed element. It provides a secure attachment point for the themed element while remaining itself attachable to the strap, thus mediating between the need for stability and the need for removability.
3Adaptability or versatility
If custom-themed elements are created for each chair, then personalization is maximized, but the complexity and number of components increases
Solution Approach 1:
The strap and holder are designed as universal components that can be used with any themed element and any chair type. This allows users to personalize by changing only the themed element while reusing the same strap and holder, thus maintaining personalization capability while minimizing the number of components.
Solution Approach 2:
The themed element is extracted as a separate, interchangeable component from the overall assembly. This allows the personalization function to be achieved by simply changing the themed element while keeping the structural components (strap and holder) constant, thereby reducing overall system complexity.

AI summary
Assemblies for chairs, chair assemblies and methods of attaching assemblies to chairs are disclosed. An assembly for a chair having a chair back includes a strap that surrounds at least a portion of the chair back such that the strap is held on the chair back in a held position and a themed element coupled to the strap in the held position.
