Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser scanning sensors require disassembly for adjusting the detection area, which is not feasible due to safety and structural constraints, limiting flexibility in installation on ceiling and wall surfaces.
Innovation Solution
A laser scanning sensor with a head part shaped like a virtual cube, featuring a wiring hole at the intersection of orthogonal planes and attachment portions, combined with a joint part having a partially cutaway spherical fitted portion, allowing flexible installation patterns and fine adjustments via a resilient member, enabling waterproof and versatile mounting on ceiling and wall surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the laser scanning sensor is firmly fixed to maintain stable range measurement, then measurement precision is improved, but adaptability in installation location and orientation deteriorates
Solution Approach 1:
The sensor is divided into a head part and a base part connected by a joint part. The head part containing the laser range finder can be independently adjusted relative to the base part, allowing the measurement function to be separated from the mounting function. This enables stable range measurement while providing installation flexibility at various locations and orientations.
Solution Approach 2:
The joint part provides dynamic adjustability between the head part and base part. The attachment portions with multiple orientations allow the head part to be positioned at different angles relative to the base part, enabling adaptation to various installation surfaces (ceiling, wall, etc.) while maintaining firm fixation for precise measurement.
2Adaptability or versatility
If the detection area direction is changed by changing installation location and orientation, then adaptability is improved, but device complexity increases due to dedicated attachment members
Solution Approach 1:
The base part serves multiple functions: it provides mounting to various surfaces (ceiling, wall, etc.) and simultaneously serves as the reference frame for the adjustable head part. The joint part with multiple attachment portions provides both mechanical connection and orientation adjustment in a single integrated structure, eliminating the need for multiple dedicated attachment members.
Solution Approach 2:
Instead of changing installation location in three-dimensional space to adjust detection area direction, the invention provides adjustment capability within the joint part connection dimension. The multiple attachment portions at different orientations allow direction change without requiring physical relocation of the entire sensor assembly.
3Reliability
If the main body structure is made non-disassemblable for safety during laser irradiation, then reliability is improved, but ease of operation for adjusting detection area deteriorates
Solution Approach 1:
The sensor is segmented into a head part and base part that remain connected during operation. The head part can be adjusted relative to the base part through the joint part without requiring disassembly of the main body cover or housing, thus maintaining safety during laser irradiation while enabling detection area adjustment.
Solution Approach 2:
The joint part provides a dynamic adjustment mechanism that allows the head part to be repositioned without disassembling the main body. The attachment portions can be engaged or disengaged independently while the laser housing remains intact and secure, enabling operation adjustment without compromising structural integrity or safety.
