Massage Head Groove Locking for Stable Quick Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage apparatuses face issues with complicated design, inconvenient mounting, and insufficient connection stability, leading to potential safety hazards and a suboptimal user experience due to massage heads falling off.
Innovation Solution
A massage component with a lead-in groove and a clamping groove on the massage connecting member, featuring a protruding point that fits into the grooves for stable connection, enhanced by a sealing rubber ring and anti-slip treatment, ensuring secure and easy attachment of the massage head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connecting components are used, then the massage apparatus can be assembled, but the connection stability is insufficient and the massage head may fall off during use
Solution Approach 1:
The connecting member is divided into distinct functional features: a lead-in groove for guiding the protruding point during assembly, and a clamping groove for securing the protruding point in place. This segmentation allows the connection mechanism to simultaneously provide easy mounting through guidance and stable connection through the clamping groove.
Solution Approach 2:
The protruding point on the massage head acts as an intermediary element that fits into the lead-in groove and clamping groove of the connecting member. This intermediary feature enables the massage head to be securely attached while maintaining ease of assembly through the guided insertion path provided by the lead-in groove.
2Reliability
If conventional connecting components are used, then the massage apparatus can be assembled, but the design becomes complicated
Solution Approach 1:
The lead-in groove and clamping groove are merged into a single integrated feature set on the connecting member. The lead-in groove naturally transitions into the clamping groove, combining the guiding and securing functions into one continuous structural element, thereby simplifying the overall design while maintaining connection stability.
Solution Approach 2:
The connecting member's groove structure serves multiple functions: the lead-in groove provides guidance during assembly, the clamping groove ensures secure attachment, and together they prevent the massage head from falling off. This multi-functionality reduces the need for additional separate components, simplifying the overall design.
3Reliability
If the massage head is securely attached, then connection stability is improved, but the mounting process becomes more difficult
Solution Approach 1:
The lead-in groove is designed to preliminarily guide the protruding point into the correct position before the final clamping action occurs in the clamping groove. This preliminary guiding action makes the mounting process easier by providing a clear insertion path, while the subsequent clamping groove ensures secure attachment.

AI summary
A massage component with a lead-in groove and a clamping groove includes a massage head and a massage connecting member. An inner side of the massage connecting member is provided with the lead-in groove and the clamping groove, and the clamping groove is annularly arranged on the massage connecting member. One end of the lead-in groove extends to a side edge of the massage connecting member, and the other end of the lead-in groove communicates with the clamping groove. The massage head is provided with a protruding point, and the protruding point fits with the clamping groove and the lead-in groove. When the protruding point completely enters the clamping groove, a firm connection is formed between the massage head and the massage connecting member, which ensures stability during massage, and facilitates quick disassembly when the massage head needs to be replaced.
