Bed sheet holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed sheet holders with strip-shaped sheet bodies suffer from low strength, ease of being pulled apart, and increased transportation costs due to their length.
Innovation Solution
A bed sheet holder design featuring a bracket with multiple sleeving members and sliding blocks, where the sleeving members are sleeved onto sliding blocks from the outer side, enhancing fixation and reducing the likelihood of being pulled apart, and incorporating a detachable structure to minimize packaging volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strip-shaped sheet body is used to fix the bed sheet, then the bed sheet can be held in place, but the strip-shaped sheet body is easy to be pulled apart and has low strength
Solution Approach 1:
The patent divides the original strip-shaped sheet body into multiple separate sleeving members (first sleeving member, second sleeving member, etc.), each independently sleeved on sliding blocks. This segmentation transforms a single weak structural element into multiple reinforced components, where each sleeving member can independently bear load and resist pulling forces, thereby significantly improving overall strength and fixation reliability.
Solution Approach 2:
The patent implements a nested structure where sleeving members are sleeved over sliding blocks, which are themselves part of the bracket structure. The sliding blocks are inserted into sliding slots within the sleeving members, creating a nested configuration. This nesting provides mechanical interlocking and distributes stress across multiple interfaces, preventing the sheet body from being easily pulled apart while maintaining reliable bed sheet fixation.
2Reliability
If a strip-shaped sheet body is used to fix the bed sheet, then the bed sheet can be held in place, but the length of the strip-shaped sheet body is relatively long, which increases transportation costs
Solution Approach 1:
The patent segments the long strip-shaped sheet body into multiple shorter sleeving members (first sleeving member, second sleeving member, etc.), each with a manageable length. These segmented components can be independently packaged and transported, significantly reducing packaging volume and transportation costs compared to a single long strip, while maintaining effective bed sheet fixation through the distributed arrangement of multiple sleeving members.
3Strength
If the sleeving member is sleeved on the first sliding block from the outer side, then the fixation is enhanced and the likelihood of being pulled apart is reduced, but the structure becomes more complex
Solution Approach 1:
The patent employs a nested structure where the sleeving member is sleeved over the sliding block, which is itself nested within the sliding slot of the sleeving member. This nested configuration provides inherent mechanical interlocking and structural reinforcement without requiring additional fastening mechanisms or complex assembly steps. The nested design naturally resists pulling forces while maintaining relatively simple manufacturing and assembly processes.

AI summary
A bed sheet holder includes a bracket and sleeving members. The bracket includes a bottom plate, supporting members arranged on the bottom plate, and first sliding blocks arranged on the supporting members. A first sliding slot is defined in the sleeving member. At least one end of the first sliding slot is a first opening. The first sliding block is arranged inside the first sliding slot. When the bracket is used in conjunction with a bed sheet, the bottom plate is pressed under a mattress, the supporting member is attached to an outer side wall of the mattress, the first sliding block is exposed on an outer side of the mattress, and the sleeving member is sleeved on the first sliding block through the first sliding slot, thereby pressing one part of the bed sheet between the sleeving member and the first sliding block to fix the bed sheet.
