Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging-bracket devices for wall cupboards often require additional components and complex activation processes to prevent accidental disengagement, increasing manufacturing and assembly costs and time.
Innovation Solution
A concealed and adjustable hanging-bracket device with a square-shaped arm stop positioned beneath the wall rod, ensuring stable positioning and preventing disengagement without additional parts, utilizing a spindle nut and gear mechanism for vertical adjustment and a cross-shaped screw for horizontal adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components (such as grub screws) are added to prevent disengagement, then reliability improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the anti-disengagement function directly into the hanging bracket structure by forming a protrusion on the arm that engages with a corresponding recess in the support. This integration eliminates the need for separate locking components like grub screws, thereby maintaining reliability while reducing device complexity and manufacturing cost.
Solution Approach 2:
The hanging bracket's arm automatically performs the anti-disengagement function through its own geometric features (protrusion and recess engagement) without requiring external locking mechanisms or additional activation steps. The structure itself provides the safety function, eliminating the need for separate components.
2Reliability
If additional components and activation steps are required, then anti-disengagement reliability improves, but assembly time and productivity decrease
Solution Approach 1:
The anti-disengagement mechanism is combined with the main hanging bracket structure, allowing the entire assembly to be installed in a single operation. The protrusion-recess engagement occurs automatically during the normal installation process, eliminating separate activation steps and improving assembly productivity while maintaining reliable fixing.
Solution Approach 2:
The anti-disengagement features (protrusion on the arm, recess in the support) are pre-formed as integral parts of the hanging bracket structure during manufacturing. This preliminary preparation ensures that the safety function is automatically activated during normal installation without requiring additional assembly steps, thereby improving productivity.
3Adaptability or versatility
If the arm is allowed to rotate freely for adjustment, then adaptability improves, but stability deteriorates when upward force is applied
Solution Approach 1:
The arm is designed with dynamic characteristics that allow free rotation during the installation and adjustment phase, enabling adaptability. Once positioned, the protrusion-recess engagement automatically activates to provide mechanical interlocking that prevents upward disengagement, thus achieving both adjustability and stability.
Solution Approach 2:
The protrusion on the arm is preliminarily positioned to engage with the recess in the support before any upward force can cause disengagement. This preliminary geometric constraint prevents the harmful effect of accidental upward thrust while maintaining the ability to adjust position during installation by rotating the arm within the allowed range.
