Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lens modules in terminal devices, such as cameras and mobile phones, are difficult to disassemble for repair or replacement, often requiring tools that can cause damage to the module or other components.
Innovation Solution
A lens module design that includes a structural member with a pulling portion, allowing the lens assembly to be disassembled without external tools by pulling on the pulling portion, thereby minimizing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lens module is made smaller to fit terminal devices, then the size of the lens module is reduced, but the difficulty of disassembly increases and tool damage risk increases
Solution Approach 1:
The lens module is divided into separable components: a lens assembly and a pulling portion that can be detached from the terminal device. The pulling portion acts as an independent extraction element that allows the lens assembly to be separated into discrete parts for easy removal and replacement.
Solution Approach 2:
The pulling portion serves as an intermediary element between the lens assembly and the terminal device housing. This intermediary structure provides a dedicated interface for tool-free extraction, allowing the lens module to be removed without requiring direct manipulation of the lens assembly itself or risking damage to other components.
2Device complexity
If traditional lens modules are designed for compactness, then device size is reduced, but tool-free disassembly becomes impossible and component damage risk increases
Solution Approach 1:
The lens module design transitions from a static, permanently fixed structure to a dynamic, reversible connection. The pulling portion enables the lens assembly to move between a fixed installed state and a removable extracted state, allowing easy disassembly and reassembly without tools while maintaining compact integration during normal operation.
Solution Approach 2:
The pulling portion is extracted as a separate functional element from the traditional lens module design. This extracted component provides a dedicated extraction interface that allows the lens assembly to be removed without tools, separating the disassembly function from the lens assembly itself and enabling tool-free operation.
3Stability of the object's composition
If the lens module uses traditional fixed designs, then structural stability is maintained, but disassembly requires tools that can cause damage to the lens module or other components
Solution Approach 1:
The pulling portion acts as an intermediary extraction element that absorbs the mechanical stress and force required for disassembly. By providing a dedicated interface for tool-free removal, it prevents direct contact between removal tools and the lens module components, thereby eliminating the risk of tool-induced damage to the lens assembly or surrounding components.
Solution Approach 2:
The lens module design incorporates self-service disassembly capability through the pulling portion. The structure enables the lens assembly to be removed and reinstalled by the user without external tools or specialized equipment, allowing the system to service itself while maintaining structural integrity and preventing damage during the disassembly process.

AI summary
An easily disassembled lens module in a terminal device includes a lens assembly, a circuit board, and a structural member. The circuit board includes a first portion, a second portion, and a third portion which are connected in sequence. The first portion is connected to the lens assembly, the second portion and the third portion protrude from the lens assembly. The structural member includes a connecting portion fixed on the third portion and at least one pulling portion protruding from the third portion. After installation in the terminal device, the lens assembly can be disassembled by using the at least one pulling portion to pull on the structural member so that the lens assembly can be disassembled without using tools and without causing damage.
