Solution Overview
Problem
Existing LED lamps require the use of a screwdriver to remove and replace the lens panel, making the process inconvenient and inefficient.
Innovation Solution
An LED lamp design featuring a snap-fit assembly with elastic members and a button that allows for manual removal and mounting of the light-transmitting panel without tools, enabling quick and tool-free replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens panel is fixed on the radiator through screws, then the connection is strong and reliable, but the replacement process requires tools and is inconvenient
Solution Approach 1:
The connection mechanism is segmented into a snap-fit member with a snap-fit end and a button member, allowing the panel to be secured through distributed snap-fit points rather than requiring screw fastening. This enables tool-free installation while maintaining connection reliability through multiple engagement points.
Solution Approach 2:
The button member is designed to be movable between a pressed state (where the snap-fit member engages the panel) and a released state (where the snap-fit member disengages). This dynamic mechanism allows the connection to transition between locked and unlocked states without tools, resolving the contradiction between reliable fixation and easy replacement.
2Reliability
If the lens panel is fixed using screws, then the mounting is secure, but the replacement process is time-consuming and inefficient
Solution Approach 1:
The snap-fit member is pre-positioned on the radiator with the snap-fit end oriented toward the panel. When the panel is installed, the snap-fit member is already in place to receive the panel's engagement feature, eliminating the need for sequential screw fastening and significantly improving installation efficiency.
Solution Approach 2:
The movable button member enables rapid transition between mounted and removed states. By pressing the button, the snap-fit member is released instantaneously, allowing quick panel replacement without the time-consuming process of unscrewing multiple fasteners, thereby improving replacement efficiency while maintaining mounting security.
3Reliability
If the snap-fit member is always engaged to fix the panel, then the panel is securely mounted, but the replacement becomes difficult without tools
Solution Approach 1:
The button member serves as an intermediary mechanism between the user's hand and the snap-fit member. By pressing the button, the user activates the release mechanism that disengages the snap-fit member from the panel. This intermediary allows easy panel removal without tools while maintaining secure fixation during normal operation.
Solution Approach 2:
The snap-fit connection is made dynamic through the button's movement. In the pressed state, the snap-fit member is engaged and holds the panel securely. In the released state, the snap-fit member is disengaged, allowing easy panel removal. This dynamic switching resolves the contradiction between secure mounting and easy repair.

AI summary
An LED lamp includes a heat dissipation lamp holder, an LED lamp panel mounted on a front side of the heat dissipation lamp holder; a light-transmitting panel covering the LED lamp panel. The LED lamp further includes a snap-fit assembly, the snap-fit assembly includes a snap-fit member connected to the heat dissipation lamp holder, a first elastic member, and a button. A second elastic member is provided between the button and the heat dissipation lamp. The snap-fit member abuts against the button. When the snap-fit member is reset, an end of the snap-fit member abuts against the light-transmitting panel, the button is in a pressed state and the snap-fit member presses against the button. When the snap-fit member is in a pulled-out state, the end of the snap-fit member is detached from the light-transmitting plate, the button is bounced and abuts against the snap-fit member.
