Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring devices for doors and windows are complex to use, require precise manual alignment, result in inconsistent final shapes and sizes, create irreversible couplings, and need tools for assembly, making them inefficient and inconvenient.
Innovation Solution
An anchoring device with a main body featuring a shaped portion for snap coupling with a covering element and an expandable portion that can be expanded using expansion means to securely connect with a frame, eliminating the need for tools and allowing for quick and precise assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clips with threaded fixing means are used, then mechanical connection between cornice and frame is achieved, but device complexity and operation time increase
Solution Approach 1:
The patent removes the threaded fixing means from the anchoring device structure, extracting the complex fastening mechanism while retaining the essential mechanical connection function through a simplified snap-fit design with expansion means
Solution Approach 2:
The anchoring device is divided into distinct functional segments: a main body for positioning, expansion means for securing, and a cornice covering element. This segmentation allows each component to perform its specific function independently, reducing overall complexity while maintaining reliability
2Ease of operation
If manual positioning and spacing of multiple clips is performed, then anchoring devices can be positioned on the frame, but execution time and production cost increase
Solution Approach 1:
The expansion means is pre-configured within the main body at predetermined positions and spacings. During assembly, the operator simply needs to insert the expansion means into the frame slots, which automatically positions and spaces the anchoring devices correctly without requiring manual measurement or alignment operations
Solution Approach 2:
The anchoring device is designed to self-position and self-secure through its snap-fit mechanism and expansion means. The device automatically aligns with the frame slots and secures the cornice without requiring external tools or specialized manual dexterity, making the assembly process faster and more accessible
3Reliability
If threaded elements are used for connection, then mechanical fastening is achieved, but tool requirements and assembly complexity increase
Solution Approach 1:
The patent replaces the threaded mechanical fastening system with a snap-fit mechanical interlocking system. The expansion means expands within the frame slots to create a secure connection without requiring threads, screws, or any external fastening tools, significantly improving assembly convenience while maintaining connection strength
4Manufacturing precision
If precise manual alignment of anchoring devices is required, then high-precision doors or windows can be produced, but operator skill requirements and error rates increase
Solution Approach 1:
The anchoring device incorporates visual and tactile feedback mechanisms through the snap-fit design and expansion means that clearly indicate when the device is properly aligned and secured. The expansion means provides immediate feedback when inserted into the frame slots, ensuring correct positioning without requiring specialized operator skills or complex alignment procedures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anchoring device is easy and fast to use, ensures precise and repeatable connections, is structurally reliable, and does not require tools, thereby reducing production costs and improving the consistency and quality of doors and windows.
