Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for drawers are either complex and expensive or only fulfill limited functions, failing to efficiently connect the drawer to a running rail and allow for adjustable and secure mounting of the front panel support.
Innovation Solution
A connecting device comprising a plug-connected adapter and carrier holder with a sliding block and spring bolt, which can be coupled to a running rail and features a form-fitting design without additional fastening means, enabling vertical and horizontal adjustment and secure fixation of the front panel support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connecting device uses a multi-part structure to fulfill multiple functions (support side frame, fix front panel, connect to running rail), then the functional completeness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions into a single integrated connecting device that simultaneously supports the side frame, fixes the front panel, and connects to the running rail. This merging of functions into one component reduces the number of separate parts needed while maintaining full functionality, thereby reducing device complexity and manufacturing cost without sacrificing functional completeness
Solution Approach 2:
The connecting device is designed as a universal component that performs multiple functions: it acts as a support for the side frame, a fixer for the front panel, and a connector to the running rail. This multi-functional design allows a single component to replace what would traditionally require multiple specialized parts, reducing overall system complexity
2Reliability
If additional connecting means are added to prevent relative movement between adapter and carrier holder, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The spring bolt provides a dynamic locking mechanism that automatically engages with the locking step on the adapter. The spring-loaded design allows the bolt to flex during assembly and then lock firmly in place, providing reliable prevention of relative movement without requiring additional complex fastening means. The dynamic nature of the spring mechanism ensures consistent engagement while simplifying the overall structure
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 solution allows for a simple, cost-effective assembly that fulfills multiple functions, including connecting the drawer to a running rail, adjusting the front panel support, and preventing relative displacement, thereby reducing manufacturing costs and assembly time.
Implementation Method 1
a spring bolt with a locking step that engages in a recess in the running rail
Implementation Method 2
locking step that engages in a recess in the running rail, on the underside and set back in relation to the coupling part
Implementation Method 3
