Ironing Board Iron Rest Supported by Projecting Stringer Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ironing tables have complex structures and poorly supported heat-resistant rests, leading to instability and rigidity issues, especially when transitioning between storage and use positions.
Innovation Solution
The ironing table design eliminates the need for specific wire or tube supports by using two legs with protruding sections for enhanced stability and compactness, allowing for adjustable height and direct support of the heat-resistant rest, which is fixed to the tray using screws, welding, or riveting, and made from materials like metal, plastic, or wood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire or tube support is used to attach the iron rest to the iron plate, then the iron rest can be supported, but the structure becomes complex and less rigid
Solution Approach 1:
The iron rest support structure is merged with the side members that are already part of the ironing board framework. The side members serve dual functions: supporting the tray and supporting the iron rest, eliminating the need for separate wire or tube supports and reducing overall structural complexity.
Solution Approach 2:
The side members are designed to perform multiple functions: they provide structural support for the tray, serve as mounting structures for the iron rest, and contribute to the overall rigidity of the board. This multi-functionality reduces the number of separate components needed.
2Reliability
If the iron rest is attached using welding or clipping to a support, then the iron rest is secured, but the assembly becomes less compact and more difficult to implement
Solution Approach 1:
The iron rest is directly attached to the side members that are already integral parts of the board structure, eliminating the need for separate support components. This simplifies the assembly process and makes the overall structure more compact while maintaining secure attachment.
3Device complexity
If the iron rest is not directly supported by the side members, then the structure is simpler, but the iron rest is poorly supported and unstable
Solution Approach 1:
The iron rest support function is merged into the side members themselves. The side members are positioned and dimensioned to directly support the iron rest, providing stable support while maintaining structural simplicity without requiring additional dedicated support components.
4Volume of moving object
If the leg elements are folded parallel to the top in storage position, then the board is compact for storage, but the transition to use position requires complex sliding mechanisms
Solution Approach 1:
The leg elements are segmented into multiple sections that can fold relative to each other and to the top. This segmentation allows the legs to be compactly stored parallel to the top while enabling smooth transition to the deployed position through simple hinged movements rather than complex sliding mechanisms.
