Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical wires are bundled and exposed to the outside, then the wiring configuration is simple, but the operating space increases and wire interference risk increases
Solution Approach 1:
The electrical wire set is nested within the telescopic sheath, which itself is mounted on the shaft member. This nested arrangement allows the wires to be protected and compacted while maintaining accessibility, reducing the operating space requirement without complicating the wiring configuration excessively.
Solution Approach 2:
The electrical wire set is designed to be movable relative to the shaft member, allowing it to extend and retract. This dynamic configuration enables the wires to adapt to different operational states, reducing the maximum operating space required while maintaining electrical connectivity.
2Device complexity
If electrical wires are bundled and exposed to the outside, then the wiring configuration is simple, but wire breakage risk increases
Solution Approach 1:
By nesting the electrical wire set within the telescopic sheath, the wires are protected from external damage and interference. This nested structure shields the wires while allowing them to remain accessible for connection, thereby reducing breakage risk without significantly increasing configuration complexity.
Solution Approach 2:
The movable design of the electrical wire set allows it to be retracted and protected during non-operational states, reducing exposure to damage sources. This dynamic protection mechanism lowers wire breakage risk while maintaining simplicity in the overall wiring configuration.
3Area of stationary object
If the electrical wire set spirally moves to save space, then the operating space is reduced, but the diameter ratio must be controlled to prevent interference
Solution Approach 1:
The patent applies parameter changes by controlling the maximum and minimum diameters of the electrical wire set during its spiral movement. By maintaining the diameter ratio within the range 1.3 ≤ Dmax/Dmin ≤ 3.2, the system achieves space savings while preventing interference with other components. This parameter control enables the wire set to adapt to different operational states within safe dimensional limits.

AI summary
A connection module includes a shaft member that can be rotated in place and can be lifted up and down, two wires arranged side by side and spirally wound on the shaft member, and an holder block connected with the bottom end of the shaft member and the bottom end of each wire such that the holder block drives the two wires to expand or to contract along the axial direction of the shaft member or to spiral in the axial direction of the shaft member when the holder block is driven by the shaft member. Thus, the connection module of the present invention can simplify the conventional complicated wiring mode, thereby saving operation space and reducing the risk of line breakage.
