Angled Contact Door Hinge Shallow Installation Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door hinges require a large strap insertion depth and struggle with multi-dimensional adjustments, leading to increased installation height and effort.
Innovation Solution
A door hinge design featuring an angled contact section on the hinge bracket, which is forcibly guided and lockable in one direction, allowing for adjustable mounting with a shallow installation depth and multi-dimensional adjustment capabilities through a combination of sliding fits and mechanical adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a large strap insertion depth is used to apply sufficient holding forces, then the holding force is sufficient, but the installation height increases
Solution Approach 1:
The invention transitions from a two-dimensional clamping arrangement (strap between two plates) to a three-dimensional solution by introducing an angled contact section that engages with a receiving block in a different spatial dimension. This allows the strap to be secured without requiring deep insertion, as the angled geometry provides mechanical advantage and locking action in a compact space.
Solution Approach 2:
The angled contact section utilizes angular geometry (formally a type of curvature) to create an efficient force transmission path. The angled surfaces convert the insertion force into both holding force and locking action, achieving sufficient strap retention with minimal insertion depth compared to straight clamping arrangements.
2Adaptability or versatility
If adjustment mechanisms are added to enable multi-dimensional adjustment, then adjustment capability is improved, but the device complexity increases
Solution Approach 1:
The adjustment system is divided into independent adjustment modules: the receiving block can be adjusted independently in the receiving device, and the contact section can be independently adjusted on the receiving block. This segmentation allows each adjustment function to be simple and localized, reducing overall system complexity while providing comprehensive multi-dimensional adjustment capability.
Solution Approach 2:
The invention incorporates adjustable (dynamic) elements rather than fixed connections. The receiving block's position in the receiving device and the contact section's position on the receiving block can both be modified, enabling the hinge to adapt to various installation requirements without requiring a completely different design for each case.
