Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser point projecting devices are cumbersome and inefficient for ceiling work due to the need for a specific bracket to make the lower positioning point visible, leading to complex operations and low working efficiency.
Innovation Solution
A compact laser point projecting device with a housing and body part that are displaceable relative to each other, featuring a light source assembly that projects two positioning points along a straight line, and an opening that serves as an observation window to facilitate user positioning without additional brackets, along with a press-to-trigger switch for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific bracket is used to make the lower positioning point visible, then the positioning function is achieved, but the device complexity and operation complexity increase
Solution Approach 1:
The bracket function is merged with the housing part of the laser point projecting device. The housing part itself serves as the support structure that positions the device, eliminating the need for a separate bracket. This integration reduces device complexity while maintaining the positioning function.
Solution Approach 2:
The housing part is designed to serve multiple functions: it protects internal components, provides structural support, and acts as the positioning bracket. By making the housing part multi-functional, the device achieves reliable positioning without adding separate components, thus reducing overall device complexity.
2Reliability
If a specific bracket is used to make the lower positioning point visible, then the positioning function is achieved, but the operation process becomes cumbersome and working efficiency decreases
Solution Approach 1:
The bracket function is integrated into the housing part, so users no longer need to separately assemble or adjust a bracket. The housing part itself provides the necessary positioning, simplifying the operation process and improving ease of use while maintaining reliable positioning functionality.
3Volume of moving object
If the device is designed for compactness, then portability is improved, but the observation of positioning points may be compromised
Solution Approach 1:
The housing part is designed as a cylindrical structure with radial openings that provide observation windows. This three-dimensional design allows users to observe positioning points from multiple angles while maintaining a compact overall volume. The radial openings enable line-of-sight observation without increasing the device's footprint.
4Ease of operation
If the housing part and body part are made displaceable, then the observation function is enabled, but the structure becomes more complex
Solution Approach 1:
The body part is designed to be displaceable relative to the housing part along the axial direction. This dynamic design allows the body part to move forward, creating a hollow space that enables observation through the opening. The displacement mechanism is simple and integrated, providing the observation function without significantly increasing structural complexity.

AI summary
A laser point projecting device including a light source assembly that projects first and second positioning points respectively along two directions of a straight line. The laser point projecting device includes a housing part forming a sleeve around a body part. The body part and the housing part are displaceable relative to each other. The light source assembly is switched off when the body part is displaced to a first position along the direction of projecting the first positioning point; and the light source assembly is activated when the body part is displaced to a second position along the direction of projecting the second positioning point. The housing part has at least one opening at the end along the direction of projecting the first positioning point, and a hollow space formed between the end of the housing part close to the first positioning point and the body part.
