Handle Lock Assembly Sealing for Outdoor Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handle lock assemblies for linear movement, especially those exposed to external factors like rain and dust, lack sufficient sealing resistance, leading to reduced efficiency and hygiene concerns.
Innovation Solution
A handle lock assembly with a sealing feature, featuring a main body with a handle housing, a pivotable handle wheel, rack and pinion gears, and a base plate with a circumferentially arranged sealing member, designed to prevent dirt accumulation and ensure impermeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle lock assembly is exposed to external factors (rain, dust, temperature), then it can be used in open air environments, but the working efficiency decreases and hygiene standards are not met
Solution Approach 1:
A sealing member (gasket) is introduced to create a flexible barrier between the internal gear components and the external environment. The gasket engages with the housing to prevent ingress of water, dust, and other contaminants, while allowing the assembly to maintain its sealing effectiveness under varying temperature and humidity conditions.
2Adaptability or versatility
If the handle lock assembly operates in wet and dusty conditions, then it can function in various environments, but dirt accumulation on gear structures reduces working efficiency
Solution Approach 1:
The sealing member forms a continuous flexible barrier that prevents dirt and moisture from reaching the gear structures. This isolation eliminates the harmful effect of dirt accumulation on the rack gear and pinion gear, maintaining clean operating conditions regardless of the external environment.
3Ease of manufacture
If the handle lock assembly lacks sealing features, then it has simpler structure and easier manufacture, but it cannot meet hygiene standards and durability requirements
Solution Approach 1:
The sealing member is a relatively simple component that can be integrated into the existing housing structure without fundamentally changing the manufacturing process. It provides the necessary sealing function to meet hygiene standards while adding minimal complexity to the overall assembly.

AI summary
The invention relates to a handle lock assembly (100) for a cabinet door, the handle lock assembly (100) comprising a main body (20) having a handle housing (15) extending along a longitudinal axis (X) of the handle lock assembly (100); a handle (10) provided within the handle housing (15) and adapted to move between an unlocked position in which the handle (10) is lifted from the handle housing (15) and a locked position in which the handle (10) is substantially within the handle housing (15); a lock plug (40) provided at a lock plug housing (12) of the handle (10), having a spring-biased lock cam (42) adapted to lock the handle (10) within the handle housing (15) in the locked position. Said handle lock assembly (100) comprises at least one pivotable mounted handle wheel (35) being rotatable within the main body (20) when the handle (10) is lifted; at least one rack gear (31) and at least one pinion gear (38) in communication with the handle wheel (35) so as to convert a rotational movement from the handle wheel (35) to a linear movement wherein the pinion gear (38) is attached to a transmission bar (37) for rotating; and a base plate (30) attached to the main body (20) for substantially covering an open bottom end (25) of the main body (20).
