Chair Fastening Bracket for Secure Harness Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing children's chairs, such as the Tripp Trapp chair, face challenges in adapting to new safety requirements for harness anchoring, particularly in maintaining the correct height and depth positioning of the seat plate, especially when upgrading older chairs without causing physical damage or altering the chair's structure.
Innovation Solution
A fastening bracket with a closed hoop form featuring parallel upper and lower beams, joined by side pieces, which creates spaces to securely receive the seat plate and side member, allowing for adjustable anchoring of harnesses without altering the chair's components, using existing components for locking and allowing for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical modifications such as making holes or inserting screws are used to anchor harnesses, then secure anchoring is achieved, but the chair structure is damaged and appearance is spoiled
Solution Approach 1:
The patent introduces a fastening bracket as an intermediary component that connects the harness to the chair without directly modifying the chair structure. The bracket uses the existing grooves and side members as locking surfaces, acting as a mediator that achieves secure anchoring while preserving the original chair integrity and appearance.
2Adaptability or versatility
If the chair structure is altered to meet new safety requirements, then compliance with safety regulations is achieved, but the original chair design and functionality are compromised
Solution Approach 1:
The fastening bracket is designed as a separate, modular component that can be added to existing chairs without modifying the chair itself. This segmentation allows the safety compliance function to be added independently, preserving the original chair design while meeting new safety requirements.
Solution Approach 2:
The bracket is designed to work with the existing groove and side member structures of various chair models, providing universal compatibility. It uses the existing chair components for locking while adding the safety anchoring function, thus achieving multi-functionality without increasing overall system complexity.
3Reliability
If permanent fastening methods are used, then secure anchoring is achieved, but ease of removal and transferability are reduced
Solution Approach 1:
The fastening bracket employs a dynamic fastening system using straps and buckles that can be easily adjusted, tightened, and removed. The locking mechanism engages with the chair's grooves and side members to provide secure anchoring during use, but can be quickly released when needed, balancing security with ease of operation.
