Tap Light Sealing Structure for Water Ingress Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children's tap lights fail due to water ingress when exposed to wet environments, such as bathtubs or sinks.
Innovation Solution
A tap light design featuring a lamp holder and lampshade with an annular clamping groove that seals the connection between them, preventing water ingress, combined with a waterproof sealing mechanism for internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tap light is designed with a simple open structure for ease of manufacture and assembly, then manufacturing cost and complexity are reduced, but water ingress occurs causing device failure
Solution Approach 1:
The sealing groove is pre-formed on the lamp holder before assembly, and the sealing ring is pre-installed into the groove. This preliminary preparation ensures that when the lampshade and lamp holder are assembled together, the sealing connection is automatically established without requiring additional sealing operations, thus preventing water ingress while maintaining simple assembly process
Solution Approach 2:
A sealing ring is introduced as an intermediary element between the lampshade and lamp holder. The sealing ring fits into the pre-formed sealing groove on the lamp holder and creates a waterproof barrier when the lampshade is clamped onto the lamp holder, effectively preventing water from entering the internal cavity while adding minimal structural complexity
2Ease of operation
If the connection between lamp holder and lampshade is made loose and simple, then assembly ease is improved, but sealing performance deteriorates allowing water ingress
Solution Approach 1:
The sealing groove is pre-formed on the lamp holder body, and the sealing ring is pre-installed into this groove before the final assembly. This preliminary preparation ensures that when the lampshade is simply clamped onto the lamp holder through the clamping groove, the sealing connection is automatically established without requiring complex sealing operations or tight fastening, thus achieving both easy assembly and effective waterproofing
Solution Approach 2:
The sealing ring serves as an intermediary element that enables effective sealing with minimal clamping force. When the lampshade is loosely connected to the lamp holder through the annular clamping groove, the sealing ring maintains continuous contact between the two components, preventing water ingress while allowing for easy assembly and disassembly

AI summary
The present invention patent relates to the technical field of children's toys, in particular to a tap light. The tap light includes a lamp holder and a lampshade. A side of the lampshade is provided with a first opening that communicates with its internal space. The lamp holder is clamped at the first opening of the lampshade. An annular clamping groove is defined between base bodies for clamping the connection part. Since the annular clamping groove clamps the connection part, the two will form a seal, effectively preventing water from the external environment from entering the tap light through the gap between the lamp holder and the lampshade. Even if the child puts the tap light into the bathtub or basin while playing, or directly rinses the tap light at the sink, it will not cause the tap light to fail due to water ingress.
