Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning screws with knobs and collars are used to lock plate members, then the plate members can be securely locked together, but the assembly and disassembly process becomes complex and time-consuming requiring multiple steps and hand tools
Solution Approach 1:
The positioning device is segmented into distinct functional components: a positioning block with limiting balls for location, a separate locking mechanism with elastic members for securing, and a push block for actuation. This segmentation allows each component to perform its specific function efficiently while simplifying the overall assembly process compared to integrated screw-knob-collar systems.
Solution Approach 2:
Instead of requiring manual rotation of knobs to tighten screws as in conventional systems, this invention inverts the operation by using a linear push motion that automatically triggers the locking mechanism. The push block moves horizontally to simultaneously position and lock the plates, eliminating the need for rotational tightening operations.
2Strength
If multiple positioning screws are used to lock plate members, then the locking strength is sufficient, but the screws are easy to fall off and lose during the disassembly process
Solution Approach 1:
The positioning block acts as an intermediary component that holds the limiting balls and locking mechanism together as a single integrated unit. This intermediary structure prevents the small screw components from separating and getting lost during disassembly, while still providing sufficient locking strength through the elastic members and limiting balls.
Solution Approach 2:
Multiple positioning screws are merged into a single integrated positioning block assembly that includes the limiting balls, elastic members, and locking components. This merging ensures all small parts remain together as one unit during assembly and disassembly, eliminating the risk of individual screws being lost while maintaining the required locking strength.
3Reliability
If hand tools are used to control the locking or disassembly of the fixing device, then the locking mechanism can be securely engaged, but the assembly process requires force and hand tools which increases complexity and time
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the push block's horizontal movement. The elastic members automatically engage with the limiting balls to secure the locking position without requiring external hand tools. The system serves itself by converting the simple push motion directly into the locking action, eliminating the need for separate tightening operations.
Solution Approach 2:
The conventional mechanical system requiring hand tools (screwdrivers, wrenches) for tightening is replaced with a simplified mechanical push-block system. The horizontal linear motion of the push block directly actuates the locking mechanism through elastic members, substituting complex multi-tool mechanical operations with a single-action push mechanism that maintains locking security while dramatically improving ease of operation.
4Reliability
If screws are assembled and disassembled in narrow spaces between opposing plates, then the locking function is achieved, but the process is obstructed by surrounding objects and becomes time-consuming
Solution Approach 1:
The locking mechanism transitions from a conventional vertical screw-insertion-dimension to a horizontal push-dimension. The push block moves horizontally perpendicular to the plate thickness direction, allowing operation from the side rather than through the narrow gap between plates. This dimensional change eliminates obstruction by surrounding objects and dramatically reduces assembly time while maintaining reliable locking function.

AI summary
A push controlled positioning device includes a base with a through shaft hole, a push block horizontally and slidably coupled to the base and holding two limiting balls in two opposite through holes, and an axle seat with a shaft rod inserted into the shaft hole of the base and locked in place by the limiting balls under the effect of the elastic restoring force of an elastic member in the push block. When the push block is pushed laterally, the balls enter respective loosening grooves in the push block to unlock the axle seat, allowing removability of the base and the push block from the axle seat.
