Solution Overview
Problem
Existing information acquisition systems that use servo mobile devices to scan identification information on products are costly and do not effectively reduce production costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a servo mobile device is used to scan identification information on products, then the scanning function is achieved, but the production cost increases
Solution Approach 1:
The system divides the scanning function into two independent parts: a stationary scanner and a moving positioning device. The scanner remains fixed while the positioning device moves products under it, eliminating the need for an expensive mobile scanner while achieving the same identification information acquisition function.
Solution Approach 2:
Instead of moving the scanner over products (mobile scanning), the invention inverts the approach by keeping the scanner stationary and moving the products under it (stationary scanning). This reversal eliminates the need for costly mobile scanning equipment while maintaining scanning functionality.
2Ease of manufacture
If a stationary scanner is used with a positioning device, then the production cost is reduced, but the positioning precision must be maintained
Solution Approach 1:
The positioning device acts as an intermediary between the stationary scanner and the moving products. It includes a moving platform with blocking members that precisely control product positioning under the scanner, ensuring accurate scanning while using a simpler, lower-cost mechanism than mobile scanners.
Solution Approach 2:
The invention replaces the complex mechanical system of a mobile scanner with a simpler stationary scanner combined with a mechanical positioning device using blocking members and elastic members. This substitution maintains positioning precision while significantly reducing system complexity and cost.

AI summary
An information acquisition system includes a transmission device configured to transport a carrier carrying a number of products, an information acquisition device configured to obtain identification information of a corresponding one of the plurality of products when the carrier stops moving, a control device, and a positioning device. The positioning device includes a positioning member, a number of elastic members, a number of blocking members spaced apart and mounted on the positioning member, and a driving member fixedly coupled to the positioning member and configured to drive the positioning member to move telescopically between an extended position and a retracted position. When the positioning member is in the extended position, one of the blocking members blocks the carrier from moving. When the positioning member is in the retracted position, the blocking member that was blocking the carrier unblocks the carrier to allow the carrier to move.
