Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is used to withstand the outer gear in a conventional adjuster, then the adjuster can maintain engaging trend between inner gear and outer gear, but the supporting capability becomes weak and limited due to limited spring strength
Solution Approach 1:
The invention divides the single spring support system into multiple locking pieces (at least two) that distribute the supporting force. Each locking piece engages with corresponding grooves on the rotating plate, sharing the load and significantly enhancing the overall supporting capability without requiring a single high-strength spring.
Solution Approach 2:
The invention introduces elastic components that work in conjunction with the locking pieces to provide counteracting force. The elastic components ensure continuous contact and engagement between locking pieces and grooves, maintaining reliable supporting capability even under varying load conditions.
2Ease of operation
If a conventional adjuster uses a rotating plate with inner and outer gears, then angle adjustment can be achieved, but the operation becomes complex and the adjuster cannot achieve cyclic adjustment
Solution Approach 1:
The invention extracts and eliminates the complex outer gear component from the conventional adjuster structure. The angle adjustment function is achieved through simpler locking pieces engaging with grooves on the rotating plate, directly converting rotational motion to angular adjustment without the need for gear meshing mechanisms.
Solution Approach 2:
Instead of using gears to transmit and multiply force, the invention inverts the approach by using direct engagement between locking pieces and grooves. The force application method is reversed - users apply force directly to the rotating plate which then engages locking pieces, simplifying the transmission path and improving operational ease.
3Measurement precision
If the inner gear and outer gear are designed to engage in conventional adjusters, then angle localization can be achieved, but the adjuster fails when larger force is applied or the spring is exhausted
Solution Approach 1:
The invention segments the force-bearing function across multiple locking pieces instead of relying on a single spring-gear system. Each locking piece independently engages with grooves to provide precise angle localization, while the distributed structure prevents failure even when one locking piece wears or when larger forces are applied.
Solution Approach 2:
The invention changes the mechanical parameters of the engagement system by using multiple locking pieces with elastic components that provide continuous contact force. This ensures reliable angle localization through precise groove engagement while maintaining durability under varying force conditions, eliminating the spring exhaustion problem.

AI summary
A hinge adjuster includes a first frame, at least one locking piece, at least one spring component, at least one second frame and a pair of cover. The first frame defines at least one locking hole including a first accommodating hole and a second accommodating hole. The locking piece is slidably placed in the first accommodating hole for engaging with the first accommodating hole or the engaging notch alternatively. At least one groove for engaging with the locking piece is configured on a pivoted portion of the second frame, which includes a flat portion, a dentiform portion, and an end portion. And the locking piece is protruded from the locking hole and contacting with the flat portion, the dentiform portion or the end portion selectively. The hinge adjuster has strong supporting capability and can achieve a cyclic adjustment of angles, and the operation is simple and convenient.
