Two-Piece Connection Ring for Gas Tap Secure Mounting and Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection rings for gas taps on ovens and furnaces are difficult to mount and remove, often becoming dislocated due to loose locks, which complicates repair works.
Innovation Solution
A connection ring design featuring two engaging pieces with locking sets, fixing keys, and male tabs that securely mount to the tap shaft by opposing directional movement, ensuring stable assembly and easy disassembly through a flexible retaining protrusion and angular transition surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional washers or connecting pieces are used, then the structure is simple, but mounting is difficult and removal during repair is even harder
Solution Approach 1:
The connection ring is divided into two separate pieces (first piece and second piece) that can be mounted independently on opposite sides of the tap shaft. This segmentation allows easier installation compared to traditional single-piece washers, as each piece can be positioned and secured separately without requiring complete disassembly of existing components.
2Ease of repair
If traditional washers are used, then the structure is simple, but removal during repair works is even harder
Solution Approach 1:
By dividing the connection ring into two separable pieces with independent mounting mechanisms, the design enables easy removal during repair works. Each piece can be independently accessed and removed without requiring complete disassembly, significantly improving maintenance accessibility compared to traditional integrated washer designs.
3Ease of operation
If connection rings with loose locks are used, then mounting is easier, but the structure gets dislocated easily
Solution Approach 1:
The locking mechanism incorporates a flexible retaining protrusion that provides dynamic adaptation during mounting while ensuring secure engagement. The flexibility allows the locking elements to self-adjust and engage properly without requiring excessive force, yet once engaged, the interlocking pieces provide stable, dislocation-resistant mounting.
Solution Approach 2:
The first and second pieces are designed with self-aligning features including angular transition surfaces and complementary geometric shapes that guide proper engagement automatically during installation. This self-service mechanism ensures reliable locking without requiring complex adjustment procedures or external tools.
4Reliability
If a firm and stable mounting structure is used, then dislocation is prevented, but mounting becomes difficult
Solution Approach 1:
The flexible retaining protrusion provides dynamic flexibility during the mounting process, allowing the locking elements to adapt and engage smoothly. Once engaged, the same flexible feature maintains firm contact and prevents dislocation, thus achieving both ease of mounting and stable fixation without compromise.
