Insulation Hanger Reversible Latch for Reusable Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation panel hangers are not reversible, leading to damage and loss when disassembled, and lack effective locking indicators, resulting in potential assembly failures and increased costs in renovation.
Innovation Solution
A hanger design with a bayonet-type connection allowing for reversible locking and unlocking without damage, featuring a lock that pivots relative to the rod for secure attachment and disassembly, and includes visual and mechanical indicators for effective locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock is secured to the rod by clipping (state of the art), then the locking action is simple and effective, but the lock and rod cannot be unlocked without damage, making the hanger non-reusable
Solution Approach 1:
The locking mechanism transitions from a static irreversible clip connection to a dynamic reversible bayonet connection. The lock can be rotated relative to the rod to engage or disengage the locking position, allowing the hanger to be reused multiple times while maintaining secure locking when engaged.
Solution Approach 2:
The invention enables recovery and reuse of the hanger components (lock and rod) after use. Unlike the previous clipping method that damaged components upon unlocking, the bayonet connection allows complete disassembly and reuse of all parts, significantly reducing material waste and replacement costs.
2Device complexity
If the clipping is done inside the lock (state of the art), then the locking mechanism is compact, but it is not visible to the installer, making it difficult to verify effective locking
Solution Approach 1:
The invention incorporates visual indicators (such as colored marks or positioned features) that change appearance or position based on the locking status. When the lock is properly engaged with the rod, the indicator becomes visible to the installer, providing immediate feedback that locking is effective without requiring inspection of internal clipping mechanisms.
3Strength
If the hanger is made expensive (state of the art), then the materials and construction quality are high, but the cost of renovation increases when hangers cannot be reused
Solution Approach 1:
The reversible bayonet connection enables complete recovery and reuse of the hanger components after insulation panel replacement. This transforms the hanger from a single-use expensive component into a reusable asset, maintaining high construction quality while eliminating the need to purchase new hangers during renovation projects.

AI summary
The hanger (1) for insulation material has a rod (2) having a first end (2a) being fixed to a framework, a cup (3) fitted around and secured to the rod (2) towards a second end ( 2b) by first securing means carried by the cup and the stem, a latch (5) being fitted around the stem (2) between the second end (2b) and the cup comprising second securing means with the stem (2) cooperating with complementary fastening means (6a) carried by the rod and performing a locking action of the cup. The second securing means (6) are removable securing means allowing subsequent disassembly of the lock (5) relative to the rod (2) and the securing of the lock to the rod is effected by pivoting of the lock (5) by relative to the longitudinal axis (8) of the rod (2).
