Bed Frame Non-Rigid Gap Locking to Reduce Metal Collision Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal bed frames generate noise due to collisions and friction between metal mounting parts and slots when the frame swings, causing an unpleasant user experience.
Innovation Solution
A bed frame design featuring metal brackets with slots and non-rigid gap locking pieces, including limit plates and buckles that clamp onto the metal brackets, preventing direct contact between metal mounting parts and slots to reduce friction and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If metal mounting parts are directly inserted into slots of metal brackets, then installation is simple and fast, but noise is generated due to collision and friction between metal components when the bed frame swings
Solution Approach 1:
The patent introduces a non-rigid gap locking piece as an intermediary component between the metal mounting part and the slot. This locking piece includes a limit plate with a limit notch and a first buckle that passes through the slot to be clamped on the inner surface of the metal bracket. The limit notch prevents the metal mounting part from directly contacting the slot walls, eliminating metal-on-metal collision and friction noise while maintaining secure attachment.
2Ease of operation
If a gap is left between metal mounting part and slot inner wall to enable smooth insertion, then installation is facilitated, but the bed frame shakes and generates noise when used
Solution Approach 1:
The non-rigid gap locking piece serves as a mediator that fills the gap between the metal mounting part and the slot. The first buckle passes through the slot and clamps onto the inner surface of the metal bracket, while the limit plate with limit notch positions the metal mounting part to prevent direct contact with the slot walls. This eliminates both the harmful gap-induced noise and maintains installation ease.
Solution Approach 2:
The patent employs a non-rigid (flexible) gap locking piece that can deform to accommodate the gap between the metal mounting part and the slot. The flexible material allows the locking piece to be inserted easily while maintaining contact pressure to prevent metal-to-metal contact, thus reducing noise without compromising stability.
3Strength
If metal mounting parts directly contact slot inner walls, then structural stability is maintained, but friction and collision noise occur during bed frame movement
Solution Approach 1:
The non-rigid gap locking piece acts as an intermediary that prevents direct contact between the metal mounting part and the slot inner walls. The first buckle clamps onto the metal bracket inner surface while the limit plate positions the mounting part, creating a noise-free interface that maintains structural stability through the flexible locking mechanism.
Solution Approach 2:
The patent changes the physical state of the gap locking piece to be non-rigid/flexible, allowing it to deform and adapt to the gap between components. This flexibility enables the locking piece to maintain contact pressure for stability while preventing metal-to-metal contact that causes noise.
