Pull-out Faucet Weight Assembly with Nested Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight assemblies for pull-out faucets are inconvenient for assembly and disassembly, and the locking buckles can interfere with other pipe fittings under the countertop, hindering smooth movement.
Innovation Solution
A weight assembly composed of two mating weight bodies connected by a locking buckle and a connecting plate, with engaging buckle and recess, and limiting structures, allowing for tool-free, single-handed operation and assembly, ensuring the locking buckle does not protrude beyond the surface, preventing interference with other fittings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional weight is made of metal material with a through hole and locked by a fastener (such as a bolt), then the weight can clamp the hose tightly, but the assembly and disassembly of the weight and position adjustment are inconvenient
Solution Approach 1:
The weight assembly is divided into two separate weight bodies (first weight body and second weight body) that can be independently positioned and assembled. This segmentation allows the hose to be clamped securely between the two bodies while enabling easy assembly by simply bringing the two bodies together and disassembly by separating them, eliminating the need for fasteners.
2Ease of operation
If another conventional weight is a combination of a plastic casing and a metallic block connected through a hinge and locking buckle, then the installation is convenient, but the locking buckle protrudes beyond the surface of the weight and may interfere with other pipe fittings under the countertop
Solution Approach 1:
The locking mechanism is nested within the weight assembly structure. The first and second weight bodies are designed with complementary surfaces that interlock when brought together, with the locking interface contained entirely within the boundaries of the weight assembly. This nesting approach provides convenient installation while preventing any protruding elements from interfering with other pipe fittings under the countertop.
3Reliability
If the locking buckle protrudes beyond the surface of the weight, then it can provide a locking mechanism, but it may interfere with other pipe fittings under the countertop to affect the movement of the pull-out faucet
Solution Approach 1:
The locking mechanism is merged with the overall weight assembly structure rather than being a separate protruding component. The first and second weight bodies are designed to mate together with their locking interfaces integrated into the mating surfaces, creating a compact unit that maintains reliable locking while adapting smoothly to the space constraints under the countertop and allowing free movement of the pull-out faucet.

AI summary
A rapid installation structure of a weight assembly is disclosed. The weight assembly includes a left weight body and a right weight body to mate with each other. First sides of the left weight body and the right weight body are fixedly connected through a connecting plate. Opposite second sides of the left weight body and the right weight body are clasped through a locking buckle. The left weight body includes a left weight and a left casing covering the left weight, and is formed with a left mating face. The right weight body includes a right weight and a right casing covering the right weight, and is formed with a right mating face. The locking buckle includes an engaging buckle and an engaging recess to mate with each other. The engaging buckle and the engaging recess are disposed on the left and right mating faces, respectively.
