Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink fixing devices are inefficient due to insufficient clamping force, limited versatility, and complexity in installation, often requiring additional thickness or adhesives to secure sinks of varying dimensions.
Innovation Solution
A device comprising a guide body with an anchoring and retaining mechanism that allows adjustable positioning and tilting, using expansion plugs and a retaining element with a threaded member to apply clamping force, ensuring stable fixation without adhesives, and accommodating a wide range of sink and plane thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If clamping force is applied parallel to anchoring means extraction direction, then clamping action is achieved, but anchoring means may come out from seats reducing fixing reliability
Solution Approach 1:
The patent inverts the traditional clamping force direction by applying it perpendicular to the anchoring means extraction direction. The retaining element pushes against the plane surface while the anchoring means anchors to the sink, creating a clamping action that prevents sink movement without risking anchoring means dislodgement.
Solution Approach 2:
The patent introduces adjustable positioning mechanisms that allow the fixing device to adapt dynamically to different sink and plane thickness combinations. The retaining element can be positioned at multiple locations along the guide body, enabling the operator to optimize the clamping force application point based on specific installation requirements.
2Reliability
If adhesives are used to improve anchoring means constraint, then fixing reliability is improved, but installation complexity increases
Solution Approach 1:
The patent makes the fixing device self-sufficient by generating its own clamping force through the retaining element pushing against the plane surface. This mechanical self-service eliminates the need for external adhesives or chemical bonding agents, simplifying the installation process while maintaining high fixing reliability.
3Manufacturing precision
If fixing device is configured for determined dimensional range, then manufacturing precision is achieved, but versatility is reduced
Solution Approach 1:
The patent creates a universal fixing device that can accommodate various sink and plane thickness combinations through adjustable positioning mechanisms. The guide body with multiple positioning locations and the slidable retaining element allow the same device to function effectively across a wide range of dimensional configurations, eliminating the need for multiple specialized devices.
Solution Approach 2:
The patent introduces dynamic adjustability allowing the device to adapt to different dimensional requirements. The retaining element can be repositioned along the guide body, and the anchoring body can be adjusted relative to the guide body, enabling the fixing device to optimize its configuration for each specific installation scenario.
4Adaptability or versatility
If additional thickness is interposed for insufficient plane or sink thickness, then adaptability is improved, but installation complexity increases
Solution Approach 1:
The patent replaces static thickness compensation (additional interposed layers) with dynamic adjustment mechanisms. The adjustable positioning systems allow the retaining element and anchoring body to be repositioned to accommodate varying thicknesses directly, eliminating the need for additional compensating materials or layers.
