Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flashlight modules in handheld electronic devices face design challenges due to the need for re-designing light-transmissive covers to match varying device shapes and thicknesses, leading to assembly errors and reduced universal design compatibility.
Innovation Solution
An adjustable distance is created between the flashlight element and the circuit board using an elastic conductive terminal set, allowing for flexible assembly in devices of different shapes and thicknesses, and enabling common assembly of the light emitting diode and cover to the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the light-transmissive cover is designed to match the specific shape and thickness of a mobile phone housing, then the assembly fit is improved, but the design complexity and inventory requirements increase due to the need for different covers for different device models
Solution Approach 1:
The light-transmissive cover is designed with a universal structure that can accommodate multiple mobile phone models with different shapes and thicknesses. The cover incorporates an adjustable support structure that can be positioned at different locations to adapt to varying device geometries, eliminating the need for model-specific cover designs while maintaining proper assembly fit.
Solution Approach 2:
The support structure within the light-transmissive cover is designed to be adjustable and reconfigurable. The support can be positioned at different locations along the circuit board to accommodate varying thicknesses and shapes of different mobile phone models. This dynamic adaptability allows a single cover design to serve multiple device configurations without compromising assembly precision.
2Ease of operation
If the light emitting element and light-transmissive cover are assembled to different parts respectively, then the assembly flexibility is improved, but the assembly error between components increases
Solution Approach 1:
The light emitting element and light-transmissive cover are merged into a single integrated assembly unit. The support structure is incorporated within the cover itself, creating a pre-assembled module that maintains fixed relative positions between the light emitting element and cover. This integrated module is then assembled as one unit to the circuit board, eliminating cumulative assembly errors while preserving assembly flexibility through the adjustable support structure.
3Manufacturing precision
If conventional flashlight modules are designed for specific device models, then the assembly compatibility is improved, but the productivity and cost efficiency decrease due to repeated re-design requirements
Solution Approach 1:
The flashlight module is designed as a universal assembly that can be installed in multiple mobile phone models with different shapes and thicknesses. The adjustable support structure allows the same module to adapt to various device configurations without requiring re-design or re-tooling. This universal design maintains assembly compatibility across different models while significantly improving fabrication efficiency by eliminating repeated design cycles.
