Pull-out for hanging trousers and/or items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out devices for hanging trousers and clothing items in furniture compartments suffer from space inefficiency, complexity of construction, durability issues, and difficulty in accessing and cleaning, leading to unwanted folding and tangling of garments.
Innovation Solution
A pull-out device with a support element that rotates on a plane parallel to the floor, allowing secondary support elements to extend and retract, and includes modular and extendable components for optimal space utilization and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sliding guides are used to allow pull-out movement, then ease of operation is improved, but reliability deteriorates due to jamming and sliding blocks causing breakage
Solution Approach 1:
The patent replaces the sliding guide mechanism with a rotating mechanism. Instead of sliding along guides perpendicular to the bottom, the pull-out rod rotates around a fixed pin located near the front opening. This substitution eliminates the sliding blocks and guides that cause jamming and breakage, while maintaining ease of operation through simple rotational movement.
2Volume of moving object
If straight rods overlap each other in the height direction, then space utilization is improved, but device complexity increases and durability decreases
Solution Approach 1:
The patent divides the hanging space into multiple independent horizontal levels, each with its own rod that rotates independently around the fixed pin. This segmentation allows multiple rods to occupy the same horizontal plane without overlapping in the height direction, simplifying the mechanism while effectively utilizing vertical space through stacked horizontal layers.
3Volume of moving object
If multiple rods are arranged inside the housing compartment, then space utilization is improved, but ease of operation deteriorates due to difficulty in extracting specific garments
Solution Approach 1:
The patent makes the rod system dynamic by enabling rotation around the fixed pin. The rod can rotate between a retracted position (parallel to the compartment depth) and an extended position (perpendicular to the compartment depth), allowing the user to easily access and extract specific garments by simply rotating the rod outward, while maintaining compact storage when not in use.
4Volume of moving object
If rods are arranged to overlap in the height direction, then space utilization is improved, but harmful factors increase due to unwanted folds and tangling of garments
Solution Approach 1:
The patent transitions from vertical stacking (height direction) to horizontal layering with rotational access. Multiple rods are arranged at different heights but extend horizontally in opposite directions from the fixed pin, allowing garments to hang without overlapping or tangling, while still utilizing vertical space through the stacked horizontal layers.
5Adaptability or versatility
If a mutual rotation mechanism is used between rods, then adaptability is improved, but device complexity increases and reliability decreases
Solution Approach 1:
Instead of having rods rotate mutually around each other, the patent inverts the mechanism by fixing the pin and having all rods rotate around this single fixed point. This simplifies the mechanism while maintaining adaptability, as each rod can independently rotate to the required position without interfering with others.
6Ease of manufacture
If sliding pull-outs are spaced apart from each other, then ease of manufacture is improved, but space utilization deteriorates due to generating unused space
Solution Approach 1:
The patent merges multiple rod functions into a single rotational system around one fixed pin. The rods are positioned closely together horizontally, maximizing space utilization without requiring spacing for sliding mechanisms. The fixed pin serves as a common mounting point, simplifying manufacturing while eliminating wasted space between pull-outs.
